As you plan to install fan for the hot times, A tip for automatic ventilation is to use a 12v fan for radiator car, powered directly by solar panels. Your fan will run according to the intensity of the sunlight and stop automatically by night or cloudy. It will follow the natural need of your plants.
Great video, just a suggestion on how you are supporting your ridge beam. Look at 16:48. You have 3, 2x4's sandwiched together carrying the entire load of the beam and weight placed on it. That set of 2x4's (called the header) needs to be flipped 90 degrees since a 2x4 is much stronger standing on its edge. Make your header out of two 2x4's with a piece of 1/2 inch plywood sandwiched in between, this will yield, 3 1/2 inches. Then place at least one 2x4 directly underneath each end of your header. Those 2x4's need to run all the way down to your base plate.
I’m glad you mentioned about taping the PVC piping due to the reaction to the UV plastic because a lot of vids I’ve watched on building hoop greenhouses nobody’s mentioned that except you.
I am currently running my 20ft long polytunnel up here in central oregon. Ive been heating it with a heater buddy which i saw you have in the front of your greenhouse. I just got the 5ft hose they make so it can hook up to a 5 gallon. Im running led uv grow bulbs to extend my daylight hours. Im able to keep an average of 60°f with an outside ambient temp of 10°-32°f. My brussle sprouts, swiss chard, arugala, royal purple beans, tomatoes, and green onions are doing great. Still can't wait for spring time. 1.5 months left until seeds get started 😁🌱
i've literally watch 100 videos on building a green house. and then drew what i considered would be the best and most economical..and then i found this video. BASICALLY, this is what drew up,. except what i drew was slightly smaller..however, aside from actual size, this is the best design!.. GOOD JOB!! EXCELLENT!!
I built a smaller 12x20 about 15 years ago. I used 2 inch metal conduit for the top with 1 support in the center. We used it for 7 years until we sold the house. We started flower and plant seedlings and once able, we would transplant most of it to container arrangements. I thought I would build another by now but haven't yet, maybe this summer! Thanks for the video and awesome job on the build!
You could install a coat hook next to the door because in the spring and fall when it’s cooler outside and you go in there and it’s warmer you’ll want to take your coat off and hang it up while you do work inside the greenhouse
Use compost inside the greenhouse for free heat. I bought mine with Colorado snow load and wind for about 1200. It did not hold up to the wind even with the extra screw downs. We will be changing things for next year. Ty for your ideas.
One thing you may consider or try is IBC totes for solar batch heater/thermal mass. I was bored last sunday and filled one with water and rattle canned it flat black. It started at 35 F that next day it was in the teens and partially froze so tuesday I threw together some old storm windows into a cube around and over it. It gets up to 80 some odd degrees F during the day inside the box, and tonight an hour after the sun went down and the residual heat in the ox dissipated I checked the water temp and it was at 60 F. I am going to keep checking it in the mornings and evenings and see how good it can get, but I think it will work for what I want it to do, and as a bonus I can capture rain water to fill them, and even use one for manure tea if I so choose. Thanks for the video!
When I lived in Japan most of the house growers over there had a fish pound in the house to heat it . With the added benefit of the fish themselves to sale , you’re plants get some tasty water to aid in the growth. Others would have metal flat pans or stones gathered in circles to put hot coils in they would toss water on the coils on some days to creat steam. I have not had to use these techniques living in Florida, however I do have a fish pound about six years in development so if we should ever get to a point of having to create a grow house I will incorporate the pound into that plan . Great video , Thank You for the tips ! Namaste ! GOD SPEED!
It's so much fun building a greenhouse. I'm in the process and I'm just making it up as I go along. You learn so much by doing that and you brain really loves you for the good workout!
Hi bro, listen since am from the middle east and know about heat and what does it do in seconds! believe me, in you case you need to put heat blower, facing up (from the end to the main door) and it works on timer, so if there is snow on that particular day, you adjust it to start on your preferred time, so it can starts blowing the heat, doing so it'll make the snow go down immediately. and in minutes the blower will go off! so simple, and you don't have to do this 12 months a year! it's just in the winter months and that's it. wish you all the best from Dubai :)
Looks good! I just relocated from NH to NC. I ran the same size house in NH for several years. 1st your beam is a great idea. 2d the second layer is a good idea. 3d ventilation!!! We hit over 100 in April. We killed everything. As I worked off the farm automate ! 4 the roll up sides for summer. 5 Elliot Colman read his works. 6 ,small fans to circulate the air. 7 heat battery where warm air is circulated from the top center of the house down and under the floor through 4 inch plastic drain tubes. . Good luck have fun.
I agree with oby-1 . Transfer all loads from above down to the ground where your base (footing) All wood on the flat will bendover time or just snap. This is easy to repair and very important good job
Just watched this video, haven't read all the comments, so I'm not sure if anyone mentioned this. The only thing holding up your center cross brace that ties into your end wall are the nails holding up your six inch side wall support. You need vertical wood supports that actually hold up the cross brace. The weight of your center support could weaken those nails/screws over time. You should take out your door and reframe that section or you risk the collapse of your side wall support. Great idea in your build but you have a major flaw that could injure you or someone else.
Very nice video and hoop house! I'm a full time contractor and part time farmer working to move from the former to the ladder for my family. Keep in mind unless you're using larch wood any lumber on the ground is going to rot. It doesn't matter if it's cedar or pressure treated the compost microbes in the dirt that we love so much for breaking down our food scraps and chicken poop will do the same to your end walls. I'm not knocking your hoop house at all I just thought I'd mention it in case it's something you hadn't thought of. As a business investment your hoop house will pay for itself many times before the lumber begins to rot out. I'm going to check out some of your other videos. Don't apologize for long winded talking videos your experience and insight are valuable. The hours a person can save by learning from your story are nothing compared to the length of the video. I will watch it again before I build a hoop house. If a person can't sit through an 18 minute video then they probably don't have patience, discipline, or persistence to grow anything anyway.
Hi, :) thats right . So I have been watching vids for a few yrs now I've have always noticed the runners in the dirt , I'm thinking painting them would do good correct ? I'm about ready to start few weeks my 30x15 ish x 7 ish tall. Any advice would be great . I see he's using gray pvc , i'm reading more on it now but seems like I've read stick w/ white pvc . I just heard on another vid the gray pvc is cheaper ? I have my windows and glass door together . I nee to pull the trigger soon , I've got a stack of re-claimed 2x4s , woogd is outragous right now $. Thanks Stay Safe .
Composting in one area will surprisingly add heat, too. Some have put nesting boxes along one side and put their chickens over winter and they help prepare the soil.
Hello from a fellow michigander! We are about to buy property and hopefully put in a greenhouse about that size. We are thinking of going with old windows rather than plastic but nothing's off limits. Ive loved watching you build yours its very informative and i thank you! Id like to put my essntial oil distiller and a woodfire run hot tub inside with my plants. Im hoping using the hot tub alot will keep it warm and moist for my darling plants!
Nice Job. I have heard many folks say who have tried it to never use pvc for your hoops. It just don't last. The uv from the sun just destroys it. Bending your own fence rail is less expensive than buying pre-fab hoops. Arch roof made from making the arches out of wood is even stronger and not that expensive ether. There are diy videos that show how they are made. You can get poly greenhouse film remnants pieces a lot cheaper from the places that sell it. Again nice job, looks good.
great looking greenhouse! if i had the room id love that large of a greenhouse. mines only like 8ft by 11 ft. im from michigan too!! glad to see more people greenhousing.
THX for your explanations, great ideas. I am building a 18x30 hoop house, 1-1/2" electrical gray PVC it has more flex, 3 ft on center. your ridge beam is a must, good idea, I went with 12 mill woven green house plastic. Northern Wisconsin! I have a smaller 12X20 hoop house, 1" schedule 80 2' on center with the same PVC for a ridge pole. 4 winters now, it held up in 2018 April 16th 33" snowfall, that was fun! I can get 1 more season out of that 6mil plastic. THX much for your video, keep up the good work:)
build tables against your end walls for support without wasting space. Will stabilize the end walls and also save some materials for one side of the table.
Thank you ! I actually like seeing the trial and error videos. It helps all of us see what worked and what didn't. I am going to put in a solar ventilation gable fan for our very hot summers.
As was mentioned before, the posts should have been under the beam, however you could bore a hole through the beam sides and posts and use a length of ready rod with large washers to fuse the two, or nail cleats under the posts. The beam will likely never be exposed to the kind of weight that would require much support so I wouldn't worry too much about it.
PVC conduit is cheaper short term but more expensive long term. I know from experience. In Sept 2017 I built a hoop house very similar to this but only 12 ft wide and 6 ft tall (50 ft long). I used the same PVC conduit and spacing of bows as in the video. It was fine until Jan 2019 when we got some 40-50mph winds blowing against the side of the greenhouse (the low temps made it worse). Several of the PVC bows broke where they were connected to the top beam. I was also drawn to using PVC because of the cost and ease of installation (no bending of steel). Sure I saved a couple hundred bucks at the time. But now I regret it. I've spent more money and a lot of time doing repairs. I repaired my PVC bows the best I could but when it comes time to replace the bows, I'll be using galvanized top rail. Another benefit of galvanized steel is it can come into contact with the plastic without degrading the plastic. @SSLFamilyDad this is a great video (as well as your others that I've watched). I just wanted to share my experience with PVC bows so maybe somebody else won't make the same mistake I made.
pvc tubing in direct contact with the greenhouse poly will result in a shorter lifespan for the poly. Never use bleach to clean greenhouse poly for the same reason ;)
Just found your website. Thanks for sharing It's been 3 years now for this greenhouse. How did it work out for you? Amazing cost savings! What was that website for the plastic? How many years do you think it will last now? What would you do different? TY.
Nice video. It’s good that the plastic is UV protected. I buy rolls of 6mil plastic from Lowe’s to cover hay when I run out of tarps that’s fairly expensive ($90-150) for ‘400, doesn’t last but 6-8 months before it becomes brittle, tares or breaks apart into tons of tiny little pieces. I’m going to try some of the plastic you used.
Very impressed the most impressive Greenhouse I have seen all night I'm going to watch everything you've done. I find it hard to believe you did that for 650 bucks I figured the plastic cost that much can't wait to find out where you got it I seen the comment you're putting links that's awesome I'm kind of excited some talking before I get through all your stuff looking forward to learning everything you've got going on there like to try to figure out how to do the wooden walls the arch is a little bit different though but we'll see thank you so much great job by now you must have yours. Seedlings Is 2020 thank you brother God bless
Looks great! I discovered your channel a few weeks ago looking for acroponics info. Your videos are perfect for me because I'm living in a similar climate and can relate to your trials and tribulations. I attempted to build a greenhouse about 3 yrs ago but failed. Thanks to this video i will try again in the spring Thank you and best wishes for future success.
Sadly PVC reacts with (eats) polyethylene cover... yes? Heck! I didn’t notice you covered covering pvc tubes with guerilla-tape just as I’d seen done elsewhere! Good work and thanks for sharing your knowledge.
Great Video! I'm a novice when it comes to green houses, but I've been working on cold weather designs that are inexpensive, insulating, load carrying and wind resistant. The concept is DIY Air-Create (Side Walls, Back Wall, Lean to Roof) poly carb glazing on only the south wall oriented verticle. I'll let you know how it turns out!
From my experience with a hoop house anytime you have hardware on the pvc (screws, bolts, etc) you should use pipe insulation or a pool noodle as a buffer. The metal rips the plastic when the wind blows
I would never have a green house of that size! Really awesome beam design! I had a shelter similar to that size and it did colapse! Aweful because it could have been a good setup! Nice to see somone else have a sucsessful large structure! I bought the structure without being shown they actualy need that beam!
Nice job. Here in Texas, PVC pipe will heat up and bow. I know this because I've used it. I now have built one using cattle wire. A 13X40. I have had a hard time bowing the boards. They too have to be reinforced at the ends, but they will also hold Wt.
Rob T I’m in South Tx and hoping to build a greenhouse. Have you shared online or could you send some pics to gatewaytraders@yahoo.com? Thanks in advance.
From Michigan Myself, White Cloud (lol). As much sun as we get prolly last 10 yrs ; immediately chuckled. Your right about that. Thanks for the knowledge.
You will be amazed at how much ventilation you need in the summer. I'm west of Pittsburgh and my 12'x20'x8' hit 110F even with a large fan on high, four screened vents open, a 2'x4' window removed, and the door wide open. Shade cloth or a white tarp will be a great help.
Hi, Family Dad It is not much talking , Information is good covers cost, where to get Plastic, how durable it is, particularly you filmed at the appropriate time, to understand how plastic holds the snow. It is very inspiring looking at the cost for beginners to start and go for fancy ones later. I have a friend was a good Gardner, spend all the necessary thing had 4 years or so and gave up the project and took up a job which requires full time. So down the road, if you gave up, it is not a big deal, lose nothing. By the way, your greenhouse is too big for many beginners but, it can be a small one with the same formate. Many greenhouse sites how to build shouldn't be there or reconsider why they are there, Wishes to your family. Thanks, Paramasivan
I had a portable garage that shape only 10 x 20, & when it snowed I took a soft broom out & gently tapped & the snow fell off just like you showed. my structure was painted metal tubes that anchored into metal strips on the ground tho. Im going to set seedlings in it soon right over the ground thell be planted in. Then take it down in May without disturbing the raised beds.
Your design is very similar to my 12x24 one I built 7 years ago. It's had over 2,000 lbs of snow on it (14") with no issues. I got 6 years of the green house fabric before needing to recover. I think off gassing from the PVC degrading the plastic is overblown... I opted not to worry about it. In six years there was a little discoloration - but the plastic did not significantly degrade where it contacts the PVC pipe. I do wonder if you've got yours anchored to the ground enough to keep it down and from twisting in a strong wind.... you have a lot of surface area there and the curved surface can actually act like an airfoil. In mine, I tied to planting beds directly into the side walls so there are thousands of pounds of earth keeping it down.
If you had to do it again, I would suggest a 45 degree fitting at the peak. We live at 1250, in Oregon, in more mild climate, but we have historically had 3+ feet of snow. The additional height and peak is hopefully going to better shed snow to the sides. Dimensions we used were 15' +45 degree fitting + 15 feet = 20 foot wide, 10 feet at peak., gothic arch barn shape.
Great informative video! You might look into compost heating. Not sure if that would be a viable option for winters as cold as yours but worth checking out. If nothing else it’s really interesting. It could be a great supplemental method to go with the water tank heat storage method. Plus come spring you’ve got fresh compost that would only need minimal moving.
My 20x12ft tunnel is sitting at 30 degrees c with no heating - I have a hotbed in the cnr built with 4 haybalesand filled with horse manure, straw and some green bits I add while weeding). The beds themselves are warm as well, due to horse manure and hay beneath my compost topping
I had been thinking of building me a wood frame and initially starting with covering with greenhouse plastic. I had thought I could get reclaimed windows as I went along and replace the plastic as time goes on each side. Is that a reasonable assumption? Can the plastic withstand being cut and maybe stapled at the ends between 2x4s? I have access to aluminum sheets I thought of using for the roof as I build up to windows possibly too.
Maybe check out livingtraditionshomestead, they have 2 16x32, and they actually use it to grow in fall, and winter and they use 1 for starting all their seeds for garden , from house to greenhouse to ground, I like both of yours, I think you both have some great ideas..
Looks good. I'm sure you saved me time since I am planing to do the same, when the weather warms up a bit. I don't have your energy. I noticed diagonal wood support on the ground, if you wish to support the back walls against hi-wind pressure, better do it from above against your beam, just like your existing supports. That'll free up the space below and looks more pro, I'd also suggest to use single Bolt n Nut or Lag bolt if you prefer instead of Deck screws. probably 1/2 " by 8 t to 10 inches long. Also strengthen the walls point of attachment to the Diagonal support, to distribute the load. thanks again
Nice build. If you can get hold of it use manure as a heat source ,as it breaks down it gives off constant heat and when Spring comes dig into the soil either inside or outside into beds.
I have a similar one that I built a couple years ago I may have it in one of my videos, I didn’t film the build but I threw it up pretty fast and the plastic only lasted for two years, this winter took its toll on it and ripped off the plastic, just found your channel got a new sub nice work I hope it lasts longer than mine did, I built mine 20 ft by 40 ft in spring of 2016
Thanks for info vlog! So happy to see it held up so well but I really had no doubts, good job! Now I just hope that you don't get too much more snow this winter, especially with this new artic front that's going to freeze us even down in Texas! Stay warm and God Bless❤
Off the wall, May I suggest a hybrid system. Rocket Mass Heater, use the "bench" to put water barrels on. Hypothetically, use solar acquired heat during the day to warm the hydroponic's barrels and structure. Then near nightfall and/or early morning, fire up the RMH. The barrels would help store AND radiate heat after the RMH burns down. Logistics might be a night mare, I don't know. I do know that other have claim to have successfully used hydroponics in grow tunnels, but they had wood heat also. Easy enough for an armchair engineer with no experience, lol & God Bless.
Another low cost heating solution for the greenhouse would be compost heating. It seems like you have all the resources you need for it: manure, wood chips, etc. The concept is pretty simple and there are a few videos on UA-cam, but none as well executed as yours. I would love to see that project!
Arms Family Homestead and Keeping it Dutch said I should check out your channel. I’ve been watching your channel and subscribed for a long time now and I think you’re a great channel. Thanks
Awesome !!! I wondered how it was going we got 12 inches of snow...another storm tonight..guess this winter is really testing your greenhouse before you get stuff growing next winter
We HAD a hoop house style green house similar to this one but it was destroyed by severe weather we had with heavy snow and winds up to 80 mph . Ours didn't have a center support like this one which would have been better but the temperatures down to zero is what really killed this thing .The plastic pipes fractured from the low temps and the snow load and especially when the winds got going ,when we had quick warm up and then heavy rain after the cold snap that's what did it for the structure . Looking back at the experience I wouldn't do it again using PVC pipes .My next one will be made with wood framing and using old aluminum double pane windows that I got from my neighbor who replaced all his windows for his entire house . This way I'll be able to open up the windows to let a breeze come through the structure without letting the insects in . For the roof I'll be using polycarbonate sheets that can withstand a load . Not sure if I'll have a concrete floor or not yet but it would be nice, and a much stronger structure plus if I use PEX pipe in the concrete and then run hot water through it ,that would be a good way to heat the structure . I'm thinking about using compost as a heat source to warm the water instead of using a stove which if done correctly will last several months and as a result will give us some good soil as well . There's so much to learn about this subject and every time I think I have a good idea of what to do I learn something new and revise my plans . Going with Aquaponics is an excellent idea. I plan on going the same route . I'd rather not use soil if at all possible because of the various things that go with using soil such as pathogens , insects etc etc . Plus I've seen huge yields from using Aquaponics . It doesn't require much electricity or water if it's done properly and low voltage pumps can be used that run off solar powered batteries . The possibilities are endless .
Just quick comment the Amish up here in mid Michigan use 6 inch thick by 10x10 inches of foam to tighten the plastic. I'm glad you was able to salvage the frame after she caved in. Hallelujah
Great job & advice on the greenhouse build! I am curious as to whether or not you needed a building permit to put up the greenhouse? I would guess that it depends on where one lives. I live in CT & I believe that something of that size would require a building permit. Of course they can then increase the yearly amount of tax that you pay.
If you find any bubble wrap...that will insulate applied inside a little....better tho is a double poly covering with air in between....this not only insulate very will....it will break strong winds too...single layer Polly House might get blown away.... Good that you used the UV Plastic.....double layer might get you up to ten years...screens everywhere..till the greenhouse gets just too warm.... Can you roll up the bottom of the plastic for air? Zone 6 here. Michigan...10 X20’ Polly house owner for years...
Im in Mississippi so i have no snow worrys dont get enough. But from living as kid in ct. My thought would be to go from the window corner of frame and make that you top of the shelf. And run it to the other window on the same side. That would make you shelf top and brace. That way it want colaspe again. And you have you shelf.
I live in N.W. Mt. and looking to build a green house. How's it holding up? Have you done any upgrades to it that you would recommend? Looks like 3 pieces of electrical conduit. Correct? Flexed them to 18feet. Looks like you spaced them 2 foot on center. I plan on using double layer plastic. Any other suggestions? Chris
Have you thought of compost heating or even underground thermal heating ( although thermal heating would be expensive ) . Compost heating is free and you also get the benefit of growing your seedlings when it matures , all free and organic. There are quite a few good sites on You Tube explaining how this can be done using leaf mold and grass cuttings etc
Love the build. I have 4 commercial greenhouses now but started with something like this one. Yours in much better than my attempt of building one though! Greenhouse growing is an addiction my friend! Best of luck! Chuck
I'll be interested in what you do for heat up in MI. Here in Nashville, our 9x13 (2foot cinderblocks below grade &4 foot 4mil twinwall ) is hard to keep 20 degrees above outdoors. I agree with your thoughts on the rocketmass stoves. better to have a slower burn but still efficient like a secondary wood gas stove solution. I tried a tent stove this year but you can only get two hours max of heat and no matter how careful, soot inside your GH. next year maybe a diy firebrick burn chamber in the ground with copper water pipes to the GH. feed clean hot air to the GH while heating water with free wood. Priority-One, heating without spending too much time doing it. Bottom line is keeping heat in & cold out. your double wall thoughts will be perfect before your current covers UV breaks down so you can get a longer life from your current cover with a new cover to take on the suns rays. one last thought - emt conduit is price comparative to pvc replacing your pvc with emt over time may be best. i saw a fair number of abandoned GH's in northern Detroit. possible source for materials ??
@@matthewlewis9996 Forgive my dumb question, I'm from Arizona. We put our coats on when its 70 degrees and we think we are going to freeze to death. What if its cloudy for a few days? The water barrels won't stay warm will they?
I have an aquaponic system in a 8x22 GH near Detroit. I was supplement heating with wood but now just use propane and keep the GH at around 55. I just measured how much it is costing me to heat the water with a 1000watt heater and it comes to about $90 a month this time of year. I think 90% of the heat loss happens in the beds and in ground sump. I stopped using wood to heat and found I have a lot more time to do other things. I see you've questioned the amount of time and labor you put into your wood boiler in other videos. I've looked into rocket mass heaters extensively and like the concept. However I plan to use a regular wood stove and just use the mass storage concept to utilize more of the heat I'm loosing and also heat the fish tank with that heat. Let me know if you plan to put aquaponics in your GH. I have a really cool concept of how to set it up.
Ventilation is important in the winter. Or you need to run a dehumidifier for disease control and somehow add c02 to the atmosphere to replace what the plants use.
Harbor Freight sells a tubing roller for ~$180, which can be used to make hoops from galvanized 1 5/8" dia fence railing (Home Depot, etc). I'm planning to use this with the hoops anchored in concrete piers. With purlins, I doubt that a wooden center beam will be necessary.
So one of my customers in CO added a Gutter deicer to the mulch in his MUCH smaller green house and it worked GREAT. and only cost about $8 a month to heat.
As you plan to install fan for the hot times, A tip for automatic ventilation is to use a 12v fan for radiator car, powered directly by solar panels. Your fan will run according to the intensity of the sunlight and stop automatically by night or cloudy.
It will follow the natural need of your plants.
Great video, just a suggestion on how you are supporting your ridge beam. Look at 16:48. You have 3, 2x4's sandwiched together carrying the entire load of the beam and weight placed on it. That set of 2x4's (called the header) needs to be flipped 90 degrees since a 2x4 is much stronger standing on its edge. Make your header out of two 2x4's with a piece of 1/2 inch plywood sandwiched in between, this will yield, 3 1/2 inches. Then place at least one 2x4 directly underneath each end of your header. Those 2x4's need to run all the way down to your base plate.
Awesome tip. Saw that also. Watch some videos from Matt Bangs Wood , Essential Carpenter for more framing tips. Good job so far.
I’m glad you mentioned about taping the PVC piping due to the reaction to the UV plastic because a lot of vids I’ve watched on building hoop greenhouses nobody’s mentioned that except you.
I am currently running my 20ft long polytunnel up here in central oregon. Ive been heating it with a heater buddy which i saw you have in the front of your greenhouse. I just got the 5ft hose they make so it can hook up to a 5 gallon. Im running led uv grow bulbs to extend my daylight hours. Im able to keep an average of 60°f with an outside ambient temp of 10°-32°f. My brussle sprouts, swiss chard, arugala, royal purple beans, tomatoes, and green onions are doing great. Still can't wait for spring time. 1.5 months left until seeds get started 😁🌱
i've literally watch 100 videos on building a green house. and then drew what i considered would be the best and most economical..and then i found this video. BASICALLY, this is what drew up,. except what i drew was slightly smaller..however, aside from actual size, this is the best design!.. GOOD JOB!! EXCELLENT!!
I disagree. A gothic arch greenhouse is far superior against snow-loads. Maybe you should watch another 100 videos?
Yep. This thing is huge. 👍💪
I built a smaller 12x20 about 15 years ago. I used 2 inch metal conduit for the top with 1 support in the center. We used it for 7 years until we sold the house. We started flower and plant seedlings and once able, we would transplant most of it to container arrangements. I thought I would build another by now but haven't yet, maybe this summer! Thanks for the video and awesome job on the build!
You could install a coat hook next to the door because in the spring and fall when it’s cooler outside and you go in there and it’s warmer you’ll want to take your coat off and hang it up while you do work inside the greenhouse
& actually, a second door to keep the heat in 😃. Nice job 👍🏼
Use compost inside the greenhouse for free heat. I bought mine with Colorado snow load and wind for about 1200. It did not hold up to the wind even with the extra screw downs. We will be changing things for next year. Ty for your ideas.
One thing you may consider or try is IBC totes for solar batch heater/thermal mass. I was bored last sunday and filled one with water and rattle canned it flat black. It started at 35 F that next day it was in the teens and partially froze so tuesday I threw together some old storm windows into a cube around and over it. It gets up to 80 some odd degrees F during the day inside the box, and tonight an hour after the sun went down and the residual heat in the ox dissipated I checked the water temp and it was at 60 F. I am going to keep checking it in the mornings and evenings and see how good it can get, but I think it will work for what I want it to do, and as a bonus I can capture rain water to fill them, and even use one for manure tea if I so choose. Thanks for the video!
When I lived in Japan most of the house growers over there had a fish pound in the house to heat it . With the added benefit of the fish themselves to sale , you’re plants get some tasty water to aid in the growth.

I have not had to use these techniques living in Florida, however I do have a fish pound about six years in development so if we should ever get to a point of having to create a grow house I will incorporate the pound into that plan . Great video , Thank You for the tips ! Namaste ! GOD SPEED!
It's so much fun building a greenhouse. I'm in the process and I'm just making it up as I go along. You learn so much by doing that and you brain really loves you for the good workout!
Hi bro, listen since am from the middle east and know about heat and what does it do in seconds! believe me, in you case you need to put heat blower, facing up (from the end to the main door) and it works on timer, so if there is snow on that particular day, you adjust it to start on your preferred time, so it can starts blowing the heat, doing so it'll make the snow go down immediately. and in minutes the blower will go off! so simple, and you don't have to do this 12 months a year! it's just in the winter months and that's it. wish you all the best from Dubai :)
Looks good! I just relocated from NH to NC.
I ran the same size house in NH for several years.
1st your beam is a great idea. 2d the second layer is a good idea. 3d ventilation!!! We hit over 100 in April. We killed everything. As I worked off the farm automate ! 4 the roll up sides for summer. 5 Elliot Colman read his works. 6 ,small fans to circulate the air. 7 heat battery where warm air is circulated from the top center of the house down and under the floor through 4 inch plastic drain tubes. .
Good luck have fun.
I agree with oby-1 . Transfer all loads from above down to the ground where your base (footing) All wood on the flat will bendover time or just snap. This is easy to repair and very important good job
Details and honesty like this are why this channel is great.
Just watched this video, haven't read all the comments, so I'm not sure if anyone mentioned this. The only thing holding up your center cross brace that ties into your end wall are the nails holding up your six inch side wall support. You need vertical wood supports that actually hold up the cross brace. The weight of your center support could weaken those nails/screws over time. You should take out your door and reframe that section or you risk the collapse of your side wall support. Great idea in your build but you have a major flaw that could injure you or someone else.
Very nice video and hoop house! I'm a full time contractor and part time farmer working to move from the former to the ladder for my family.
Keep in mind unless you're using larch wood any lumber on the ground is going to rot. It doesn't matter if it's cedar or pressure treated the compost microbes in the dirt that we love so much for breaking down our food scraps and chicken poop will do the same to your end walls.
I'm not knocking your hoop house at all I just thought I'd mention it in case it's something you hadn't thought of. As a business investment your hoop house will pay for itself many times before the lumber begins to rot out.
I'm going to check out some of your other videos. Don't apologize for long winded talking videos your experience and insight are valuable. The hours a person can save by learning from your story are nothing compared to the length of the video. I will watch it again before I build a hoop house. If a person can't sit through an 18 minute video then they probably don't have patience, discipline, or persistence to grow anything anyway.
Hi, :) thats right . So I have been watching vids for a few yrs now I've have always noticed the runners in the dirt , I'm thinking painting them would do good correct ? I'm about ready to start few weeks my 30x15 ish x 7 ish tall. Any advice would be great . I see he's using gray pvc , i'm reading more on it now but seems like I've read stick w/ white pvc . I just heard on another vid the gray pvc is cheaper ? I have my windows and glass door together . I nee to pull the trigger soon , I've got a stack of re-claimed 2x4s , woogd is outragous right now $. Thanks Stay Safe .
Composting in one area will surprisingly add heat, too. Some have put nesting boxes along one side and put their chickens over winter and they help prepare the soil.
Hello from a fellow michigander! We are about to buy property and hopefully put in a greenhouse about that size. We are thinking of going with old windows rather than plastic but nothing's off limits. Ive loved watching you build yours its very informative and i thank you! Id like to put my essntial oil distiller and a woodfire run hot tub inside with my plants. Im hoping using the hot tub alot will keep it warm and moist for my darling plants!
Kathy Hosking great idea! How about a large metal water trough during late summer, surrounded by greenery?
Nice Job. I have heard many folks say who have tried it to never use pvc for your hoops. It just don't last. The uv from the sun just destroys it. Bending your own fence rail is less expensive than buying pre-fab hoops. Arch roof made from making the arches out of wood is even stronger and not that expensive ether. There are diy videos that show how they are made. You can get poly greenhouse film remnants pieces a lot cheaper from the places that sell it. Again nice job, looks good.
great looking greenhouse! if i had the room id love that large of a greenhouse. mines only like 8ft by 11 ft. im from michigan too!! glad to see more people greenhousing.
Great info. I did't know about the PVC giving off gas that degrades the plastic sheeting. Thanks.
THX for your explanations, great ideas. I am building a 18x30 hoop house, 1-1/2" electrical gray PVC it has more flex, 3 ft on center. your ridge beam is a must, good idea, I went with 12 mill woven green house plastic. Northern Wisconsin! I have a smaller 12X20 hoop house, 1" schedule 80 2' on center with the same PVC for a ridge pole. 4 winters now, it held up in 2018 April 16th 33" snowfall, that was fun! I can get 1 more season out of that 6mil plastic. THX much for your video, keep up the good work:)
Does 6mil plastic mean plastic sheeting that is 6 millimeters thick?
No, Plastic sheeting, tarps from the hardware store, so on, are measured by thickness, smaller the # the thinner the material.
build tables against your end walls for support without wasting space. Will stabilize the end walls and also save some materials for one side of the table.
Thank you ! I actually like seeing the trial and error videos. It helps all of us see what worked and what didn't. I am going to put in a solar ventilation gable fan for our very hot summers.
As was mentioned before, the posts should have been under the beam, however you could bore a hole through the beam sides and posts and use a length of ready rod with large washers to fuse the two, or nail cleats under the posts. The beam will likely never be exposed to the kind of weight that would require much support so I wouldn't worry too much about it.
New subscriber here! I’m just getting interested in the DIY greenhouse idea. Love what you did here. Your commenters are so helpful too🙌
PVC conduit is cheaper short term but more expensive long term. I know from experience. In Sept 2017 I built a hoop house very similar to this but only 12 ft wide and 6 ft tall (50 ft long). I used the same PVC conduit and spacing of bows as in the video. It was fine until Jan 2019 when we got some 40-50mph winds blowing against the side of the greenhouse (the low temps made it worse). Several of the PVC bows broke where they were connected to the top beam. I was also drawn to using PVC because of the cost and ease of installation (no bending of steel). Sure I saved a couple hundred bucks at the time. But now I regret it. I've spent more money and a lot of time doing repairs. I repaired my PVC bows the best I could but when it comes time to replace the bows, I'll be using galvanized top rail. Another benefit of galvanized steel is it can come into contact with the plastic without degrading the plastic.
@SSLFamilyDad this is a great video (as well as your others that I've watched). I just wanted to share my experience with PVC bows so maybe somebody else won't make the same mistake I made.
Thanks for sharing your real life experience.
Add rebar inside of the pvc. Should eliminate the issue of strength.
pvc tubing in direct contact with the greenhouse poly will result in a shorter lifespan for the poly. Never use bleach to clean greenhouse poly for the same reason ;)
Electrical Metallic Tube (EMT) conduit is the way to go for durability over the long haul....
Just found your website. Thanks for sharing It's been 3 years now for this greenhouse. How did it work out for you? Amazing cost savings! What was that website for the plastic? How many years do you think it will last now? What would you do different? TY.
Nice video. It’s good that the plastic is UV protected. I buy rolls of 6mil plastic from Lowe’s to cover hay when I run out of tarps that’s fairly expensive ($90-150) for ‘400, doesn’t last but 6-8 months before it becomes brittle, tares or breaks apart into tons of tiny little pieces. I’m going to try some of the plastic you used.
It is so satisfying watching that snow fall off! Great job and great price tag!
I Know right. That was the best part of the video. I could watch that again and again. Great observation. Have a great day.
Very impressed the most impressive Greenhouse I have seen all night I'm going to watch everything you've done. I find it hard to believe you did that for 650 bucks I figured the plastic cost that much can't wait to find out where you got it I seen the comment you're putting links that's awesome I'm kind of excited some talking before I get through all your stuff looking forward to learning everything you've got going on there like to try to figure out how to do the wooden walls the arch is a little bit different though but we'll see thank you so much great job by now you must have yours. Seedlings Is 2020 thank you brother God bless
Looks great! I discovered your channel a few weeks ago looking for acroponics info. Your videos are perfect for me because I'm living in a similar climate and can relate to your trials and tribulations.
I attempted to build a greenhouse about 3 yrs ago but failed. Thanks to this video i will try again in the spring
Thank you and best wishes for future success.
Thank you for sharing your experience! I'm currently researching different styles of greenhouses, including geothermal, for year around usage.
Good video. Thank you. Good too see what flaws you had to prevent others from having the same.
Sadly PVC reacts with (eats) polyethylene cover... yes?
Heck! I didn’t notice you covered covering pvc tubes with guerilla-tape just as I’d seen done elsewhere! Good work and thanks for sharing your knowledge.
Correct, the chroline in the PVC gases off and will eat the plastic away. I covered each pipe with gorilla tape to hopefully mitigate against this
Your explanations and visuals were excellent. I stayed glued to the end of the video! Liked!!
Great Video! I'm a novice when it comes to green houses, but I've been working on cold weather designs that are inexpensive, insulating, load carrying and wind resistant. The concept is DIY Air-Create (Side Walls, Back Wall, Lean to Roof) poly carb glazing on only the south wall oriented verticle. I'll let you know how it turns out!
From my experience with a hoop house anytime you have hardware on the pvc (screws, bolts, etc) you should use pipe insulation or a pool noodle as a buffer. The metal rips the plastic when the wind blows
Great video thanks for sharing. You can use a compost pile for heat
I would never have a green house of that size! Really awesome beam design! I had a shelter similar to that size and it did colapse! Aweful because it could have been a good setup! Nice to see somone else have a sucsessful large structure! I bought the structure without being shown they actualy need that beam!
Nice job. Here in Texas, PVC pipe will heat up and bow. I know this because I've used it. I now have built one using cattle wire. A 13X40. I have had a hard time bowing the boards. They too have to be reinforced at the ends, but they will also hold Wt.
Rob T I’m in South Tx and hoping to build a greenhouse. Have you shared online or could you send some pics to gatewaytraders@yahoo.com? Thanks in advance.
From Michigan Myself, White Cloud (lol). As much sun as we get prolly last 10 yrs ; immediately chuckled. Your right about that. Thanks for the knowledge.
Been to White Cloud b4. Isnt that the Manistee Forest Preserve? Pickeral Lake?
You will be amazed at how much ventilation you need in the summer. I'm west of Pittsburgh and my 12'x20'x8' hit 110F even with a large fan on high, four screened vents open, a 2'x4' window removed, and the door wide open. Shade cloth or a white tarp will be a great help.
+Douglas Cooke I am also hoping that the nearby trees will provide quite a bit of shade in the hottest months also but we will see!
Hi, Family Dad It is not much talking , Information is good covers cost, where to get Plastic, how durable it is, particularly you filmed at the appropriate time, to understand how plastic holds the snow. It is very inspiring looking at the cost for beginners to start and go for fancy ones later. I have a friend was a good Gardner, spend all the necessary thing had 4 years or so and gave up the project and took up a job which requires full time. So down the road, if you gave up, it is not a big deal, lose nothing. By the way, your greenhouse is too big for many beginners but, it can be a small one with the same formate. Many greenhouse sites how to build shouldn't be there or reconsider why they are there, Wishes to your family. Thanks, Paramasivan
great job and information
thank you
just bought 50 acres in land in Riyadh and for sure greenhouses will be part of it.
lucky enjoy the land
Looks like a good result, appreciate you sharing the challenges and how you overcame them. Thanks for the video.
I had a portable garage that shape only 10 x 20, & when it snowed I took a soft broom out & gently tapped & the snow fell off just like you showed. my structure was painted metal tubes that anchored into metal strips on the ground tho. Im going to set seedlings in it soon right over the ground thell be planted in. Then take it down in May without disturbing the raised beds.
Your design is very similar to my 12x24 one I built 7 years ago. It's had over 2,000 lbs of snow on it (14") with no issues. I got 6 years of the green house fabric before needing to recover. I think off gassing from the PVC degrading the plastic is overblown... I opted not to worry about it. In six years there was a little discoloration - but the plastic did not significantly degrade where it contacts the PVC pipe. I do wonder if you've got yours anchored to the ground enough to keep it down and from twisting in a strong wind.... you have a lot of surface area there and the curved surface can actually act like an airfoil. In mine, I tied to planting beds directly into the side walls so there are thousands of pounds of earth keeping it down.
Thanks for the video. Looking at this idea for our community garden
If you had to do it again, I would suggest a 45 degree fitting at the peak. We live at 1250, in Oregon, in more mild climate, but we have historically had 3+ feet of snow. The additional height and peak is hopefully going to better shed snow to the sides. Dimensions we used were 15' +45 degree fitting + 15 feet = 20 foot wide, 10 feet at peak., gothic arch barn shape.
Great informative video!
You might look into compost heating. Not sure if that would be a viable option for winters as cold as yours but worth checking out. If nothing else it’s really interesting. It could be a great supplemental method to go with the water tank heat storage method. Plus come spring you’ve got fresh compost that would only need minimal moving.
My 20x12ft tunnel is sitting at 30 degrees c with no heating - I have a hotbed in the cnr built with 4 haybalesand filled with horse manure, straw and some green bits I add while weeding). The beds themselves are warm as well, due to horse manure and hay beneath my compost topping
They say 4 yrs for the plastic, mine lasted for 10 yrs. It split right at the original seams when it was folded. Good stuff. Nice looking hoop house!
How much to spend for plastic for. A greenhouse around the same size in video?
Diego M I’m not sure what it is nowadays
Thanks for sharing these tips. This is gold Jerry, gold!
Good one Banya.
I had been thinking of building me a wood frame and initially starting with covering with greenhouse plastic. I had thought I could get reclaimed windows as I went along and replace the plastic as time goes on each side. Is that a reasonable assumption? Can the plastic withstand being cut and maybe stapled at the ends between 2x4s? I have access to aluminum sheets I thought of using for the roof as I build up to windows possibly too.
Thanks for that, I live near Thunder Bay Ontario so your tips definitely apply.
Maybe check out livingtraditionshomestead, they have 2 16x32, and they actually use it to grow in fall, and winter and they use 1 for starting all their seeds for garden , from house to greenhouse to ground, I like both of yours, I think you both have some great ideas..
Looks good. I'm sure you saved me time since I am planing to do the same, when the weather warms up a bit. I don't have your energy. I noticed diagonal wood support on the ground, if you wish to support the back walls against hi-wind pressure, better do it from above against your beam, just like your existing supports. That'll free up the space below and looks more pro, I'd also suggest to use single Bolt n Nut or Lag bolt if you prefer instead of Deck screws. probably 1/2 " by 8 t to 10 inches long. Also strengthen the walls point of attachment to the Diagonal support, to distribute the load. thanks again
Nice build. If you can get hold of it use manure as a heat source ,as it breaks down it gives off constant heat and when Spring comes dig into the soil either inside or outside into beds.
I have a similar one that I built a couple years ago I may have it in one of my videos, I didn’t film the build but I threw it up pretty fast and the plastic only lasted for two years, this winter took its toll on it and ripped off the plastic, just found your channel got a new sub nice work I hope it lasts longer than mine did, I built mine 20 ft by 40 ft in spring of 2016
Thanks for info vlog! So happy to see it held up so well but I really had no doubts, good job! Now I just hope that you don't get too much more snow this winter, especially with this new artic front that's going to freeze us even down in Texas! Stay warm and God Bless❤
Very informative video I liked the details . Thanks for sharing.
Off the wall, May I suggest a hybrid system. Rocket Mass Heater, use the "bench" to put water barrels on. Hypothetically, use solar acquired heat during the day to warm the hydroponic's barrels and structure. Then near nightfall and/or early morning, fire up the RMH. The barrels would help store AND radiate heat after the RMH burns down. Logistics might be a night mare, I don't know. I do know that other have claim to have successfully used hydroponics in grow tunnels, but they had wood heat also.
Easy enough for an armchair engineer with no experience, lol & God Bless.
Radiant floor heat is much more efficient for growing. Definitely more labor involved in digging of course but the benefits are worth it.
I was about to ask about a rocket stove! Great minds!!;)
@@bdub78dub90 How deep does radiant floor heating need? I was thinking a small windmill generator next to it and use the elec to power heaters.
wos you know a lot. Do you have a channel or a site?
Thinking to covert my high tunnel 6.5ft by 8ft since I already built raised beds around the wall. Thank you for these information, really appreciated!
Thank you for the video in the end of the coming summer I am going to do something like that, the knowledge you are giving me is amazing ! Thank you!
I love your greenhouse and I will try your design when I go to build one this spring. I can't wait to see how you set up your maple syrup operation.
What an amazing comeback, sir! We're so grateful for you!
Thank you for sharing. May God bless y'all, and continue to guide and keep you. :D
Thanks man, for saving me a couple headaches. ✌🏾
Thank you for sharing all the details and cost. God bless
Another low cost heating solution for the greenhouse would be compost heating. It seems like you have all the resources you need for it: manure, wood chips, etc. The concept is pretty simple and there are a few videos on UA-cam, but none as well executed as yours. I would love to see that project!
Arms Family Homestead and Keeping it Dutch said I should check out your channel. I’ve been watching your channel and subscribed for a long time now and I think you’re a great channel. Thanks
it would be nice to have a link to the sheeting. Thanks for the cost breakdown - it was less than I would have guessed.
I like the greenhouse. Also extra storage for winter. A heater might give you 3 extra months grow time
Awesome !!! I wondered how it was going we got 12 inches of snow...another storm tonight..guess this winter is really testing your greenhouse before you get stuff growing next winter
As stone holds heat well, I'm told to give that a shot in retaining heat for night time. Haven't tried it yet to give any results on the idea.
We HAD a hoop house style green house similar to this one but it was destroyed by severe weather we had with heavy snow and winds up to 80 mph . Ours didn't have a center support like this one which would have been better but the temperatures down to zero is what really killed this thing .The plastic pipes fractured from the low temps and the snow load and especially when the winds got going ,when we had quick warm up and then heavy rain after the cold snap that's what did it for the structure .
Looking back at the experience I wouldn't do it again using PVC pipes .My next one will be made with wood framing and using old aluminum double pane windows that I got from my neighbor who replaced all his windows for his entire house . This way I'll be able to open up the windows to let a breeze come through the structure without letting the insects in . For the roof I'll be using polycarbonate sheets that can withstand a load . Not sure if I'll have a concrete floor or not yet but it would be nice, and a much stronger structure plus if I use PEX pipe in the concrete and then run hot water through it ,that would be a good way to heat the structure .
I'm thinking about using compost as a heat source to warm the water instead of using a stove which if done correctly will last several months and as a result will give us some good soil as well .
There's so much to learn about this subject and every time I think I have a good idea of what to do I learn something new and revise my plans . Going with Aquaponics is an excellent idea. I plan on going the same route . I'd rather not use soil if at all possible because of the various things that go with using soil such as pathogens , insects etc etc . Plus I've seen huge yields from using Aquaponics . It doesn't require much electricity or water if it's done properly and low voltage pumps can be used that run off solar powered batteries . The possibilities are endless .
Just quick comment the Amish up here in mid Michigan use 6 inch thick by 10x10 inches of foam to tighten the plastic. I'm glad you was able to salvage the frame after she caved in. Hallelujah
Great job & advice on the greenhouse build! I am curious as to whether or not you needed a building permit to put up the greenhouse? I would guess that it depends on where one lives. I live in CT & I believe that something of that size would require a building permit. Of course they can then increase the yearly amount of tax that you pay.
If you find any bubble wrap...that will insulate applied inside a little....better tho is a double poly covering with air in between....this not only insulate very will....it will break strong winds too...single layer Polly House might get blown away....
Good that you used the UV Plastic.....double layer might get you up to ten years...screens everywhere..till the greenhouse gets just too warm....
Can you roll up the bottom of the plastic for air?
Zone 6 here. Michigan...10 X20’ Polly house owner for years...
Im in Mississippi so i have no snow worrys dont get enough. But from living as kid in ct. My thought would be to go from the window corner of frame and make that you top of the shelf. And run it to the other window on the same side. That would make you shelf top and brace. That way it want colaspe again. And you have you shelf.
Also watch the co2 with a meter for any fuel heater you use.
I live in N.W. Mt. and looking to build a green house. How's it holding up? Have you done any upgrades to it that you would recommend? Looks like 3 pieces of electrical conduit. Correct? Flexed them to 18feet. Looks like you spaced them 2 foot on center. I plan on using double layer plastic. Any other suggestions? Chris
Very informative and straight to the point.
sweet green house. thinking of moving back to michigan good info thank you.
Have you thought of compost heating or even underground thermal heating ( although thermal heating would be expensive ) . Compost heating is free and you also get the benefit of growing your seedlings when it matures , all free and organic. There are quite a few good sites on You Tube explaining how this can be done using leaf mold and grass cuttings etc
add half inch rebar inside PVC pipe, for added strength. Weld the ends for longer lengths. Woven plastic is stronger and lasts for years
Love the build. I have 4 commercial greenhouses now but started with something like this one. Yours in much better than my attempt of building one though! Greenhouse growing is an addiction my friend!
Best of luck!
Chuck
I have had the addiction since age 12 now im over 50
how much did it run you for commercial green house
@@techno4ugeeks14 well it was 2000 for hoops and plastic only
If your thinking about waste oil heating, check out ck burners, it's a kit, works really well, I have one and it works good
I'll be interested in what you do for heat up in MI. Here in Nashville, our 9x13 (2foot cinderblocks below grade &4 foot 4mil twinwall ) is hard to keep 20 degrees above outdoors. I agree with your thoughts on the rocketmass stoves. better to have a slower burn but still efficient like a secondary wood gas stove solution. I tried a tent stove this year but you can only get two hours max of heat and no matter how careful, soot inside your GH. next year maybe a diy firebrick burn chamber in the ground with copper water pipes to the GH. feed clean hot air to the GH while heating water with free wood. Priority-One, heating without spending too much time doing it. Bottom line is keeping heat in & cold out. your double wall thoughts will be perfect before your current covers UV breaks down so you can get a longer life from your current cover with a new cover to take on the suns rays. one last thought - emt conduit is price comparative to pvc replacing your pvc with emt over time may be best. i saw a fair number of abandoned GH's in northern Detroit. possible source for materials ??
geo thermal
55gal drums painted black and filled with water. They will heat up during the day and slowly release heat overnight
Geothermal , propane heater, compost pin, black water barrels and adequate sealing will get you 40 degree difference in MI.
@@matthewlewis9996 Forgive my dumb question, I'm from Arizona. We put our coats on when its 70 degrees and we think we are going to freeze to death.
What if its cloudy for a few days? The water barrels won't stay warm will they?
@@JayJay-sf2wn i lived in Phoenix in the 80's. My sister lives in Avondale for the last 20yrs. You'll be fine
I have an aquaponic system in a 8x22 GH near Detroit. I was supplement heating with wood but now just use propane and keep the GH at around 55. I just measured how much it is costing me to heat the water with a 1000watt heater and it comes to about $90 a month this time of year. I think 90% of the heat loss happens in the beds and in ground sump. I stopped using wood to heat and found I have a lot more time to do other things. I see you've questioned the amount of time and labor you put into your wood boiler in other videos. I've looked into rocket mass heaters extensively and like the concept. However I plan to use a regular wood stove and just use the mass storage concept to utilize more of the heat I'm loosing and also heat the fish tank with that heat. Let me know if you plan to put aquaponics in your GH. I have a really cool concept of how to set it up.
Ventilation is important in the winter. Or you need to run a dehumidifier for disease control and somehow add c02 to the atmosphere to replace what the plants use.
Harbor Freight sells a tubing roller for ~$180, which can be used to make hoops from galvanized 1 5/8" dia fence railing (Home Depot, etc). I'm planning to use this with the hoops anchored in concrete piers. With purlins, I doubt that a wooden center beam will be necessary.
Hi there, thank you for sharing. How did you secure the plastic on the structure?
look into the oriental vegetables for harvesting through winter, amazing cold resistance and tasty :)
For double layer greenhouses, can you warm the air going into the inflation pump to a safe temperature? Say 110 degrees, to melt snow/ice?
your hoop house is lovely! Thank you for all the great info!
Well done. This kind of post is what realizes the miraculous potential of the Internet.
The pvc off gassing will weaken the plastic where it contacts the material. You can prime it to protect the plastic when you change it in the future
So one of my customers in CO added a Gutter deicer to the mulch in his MUCH smaller green house and it worked GREAT. and only cost about $8 a month to heat.
Would you have to worry about condensation with aquaponics or open water heating practices?
