DIY Geothermal Greenhouse Part 5: PROJECT UPDATE
Вставка
- Опубліковано 18 бер 2018
- #114 After starting to build our DIY EMT electrical metal conduit (1.25") greenhouse two years ago, we are finally back to completing this project. We're actually glad we didn't finish it then, as we would not have had the time to learn all that we have about greenhouses since that time. We would have regretted doing/not doing some of the things then, in light of what we'll be doing now.
We readily admit we are not experts at this, but doing our best to install based on all that we have read or watched on UA-cam (Ha! Don't believe everything you see on the internet) and in line with our budget. Hopefully, it all works!
In this video we are doing a project update. The past two weeks have not been super productive on the greenhouse, mostly because we had to work on other things like tree removal in order to dry out mud so we could back fill the greenhouse (see previous video). We did finalize installing EMT pipes, and started working on the timber frame end walls. Assuming we get decent weather, we should finish the greenhouse in the coming two/three weeks.
Background on the project: Our farm homestead came with metal pipes in the ground from a former 16' x 50' hoop house. It also had water lines run from the farm well (which also needed to be restored) and a 60 amp electric service. In the first video we installed the 1.25" EMT conduit that serves as the frame. In future videos we'll frame the end walls, run electric, and get the plastic cover on in time for winter.
Each rib or section of the greenhouse consists of three 10' pipes, no cutting. They are joined by stock EMT connectors. The two outer angles are 117.3. The ridge angle is 125.4. Sides are 6' tall. Just over 10' to the ridge. 16' wide.
Ultimately, this will be a double wall plastic film greenhouse.

You're boys will remember and cherish these moments for the rest of their lives.
Thank you for a great and thorough video, it's good to take our time and do it right the first time... I agree..... A hard lesson to learn when one is younger. 😊
This type of work is slow and steady. It’s straight up manual labor. Every little bit is a big win. Thank you for sharing with us. Very inspirational.
For a Newby I'm glad for all verbal and non verbal info. Thanks
Damn! Good ok downthome living! A warm but technical video. I learned a good bit. God bless.
your gear greenhouse series is AWESOME - thank you - very impressed. can't wait to see how it works for next winter
Thanks! We can't wait either!
Looks good guys. Thanks for the videos. I know how much work it is. Lots of times I am like dang why did I not video that. With the time it takes. That can slow things down big time. Been a cold March here in SC.. Hope all is will. God Bless.
Thanks, and yes, when time gets tight, making videos is usually one of the first things to go. Blessings to you and yours as well!
Thank you for all your video’s. I’m thinking about doing this on my farm.

Like the "Awful Arthur's" t-shirt! We live on Hatteras Island just down the road from Nags Head. We travel to or through the Raleigh area several times a year visiting family, would love to stop and see your place one time! God bless.
Ahh, Nags Head. We've spent a week out there every year for the past ten years. We're here working on the farm most weekends, so we'd be happy to have a visit if you're in Raleigh.
Glad to see an update! AMDG
Thanks, Fr. John! Hope you're enjoying a blessed Lent.
I'm excited to see if this works! I'm buying a farm at the end of the year and setting up two greenhouses as soon as possible and I'm currently researching ways to keep them hot/cold. Thanks for taking the time to make the video and I'm sure it will be a success. ALSO, just a thought, take a look at using DC powered fans for the setup. They are MUCH more efficient and since they will be running 24 hours a day it will add up.
Buying this farm is one of the best decisions we've made, so we hope everything works out for you. Hopefully we can wrap this series up soon (if the weather will cooperate) and show everyone the results - good and bad. When you say DC fans, I assume you mean high efficiency inline fans that run for about the cost of a light bulb?
St. Isidore's Farm Direct current over alternating current. I Know DC fans are about 70-80% more efficient than AC fans. If your inline fan pulls, say, 100 watts, then it would be 20 watts for a DC equivalent. Only catch is you need a DC power supply. About $15 on eBay. Additionally, if you are trying to keep the greenhouse a standalone unit you could power those fans with a 12 volt car battery and a solar panel perhaps I'm trying to eventually go off grid in the future
I wish you all would have placed a netting sock over the perforated pipe. It was good to use perforated pipe, but over time, you may receive sediment inside tubing with blocking sediments. The framing seems wide, I will follow your progress to see how the cross boards work. Best of luck and I think you will gain some temperature flow gain 5-15 degrees, depending on fan use.
Great project. What size pipe is in the ground connecting to the 1.25" emt conduit? You said those pipes were already in the ground from the previous owner; could I simply put the same size emt conduit 2-3 feet into the ground and join the frame conduits to it via couplings?
Where i live, pines cant grow over 40-60 feet. The tallest all get struck by lightning.
What did you do about Drainage for around the Greenhouse?!
Does the system also heat in the winter time
I am eagerly following your progress and had a couple of questions.
Why did you choose that style and framing for the greenhouse.
Is there a benefit to using a grid system for the 4" drainage tube vs a single tube 'snaked' back and forth (like LDS Prepper did in his first geo-air hoop house)?
Thanks for all of the videos and keep up the great work!
Please know that our answers are not from "experts" - we're figuring this out as we go on our smaller greenhouse in advance of building a much larger one in the same garden area. As to the style and framing, we wanted something fairly inexpensive and DIY. Using PVC was not an option because there are issues between the PVC deteriorating the greenhouse film and getting brittle over time. So while it is cheaper up front, long term it would be. We didn't want to order pipes and more expensive pipe benders, so we went this route with EMT from Lowe's. Will it work? We hope so. Question will be if the couplings can hold the weight of snow load. What I can say for sure is that they will hold my weight individually. If necessary, we could add braces. In regards to the tubing, we're using a different method we saw used by CERES out in Colorado. Most folks seem to think this will work, but have called into question using the same size tube going into the ground and and for the main branch (trunk) as for the long runs. I get where they are coming from. If this was an HVAC system, the trunk would be much larger than the supply tubes going to the registers. In retrospect, I would have used 6" tubes going down and for the trunk, and 4" for the runs. Hope this helps. We'll see soon enough if it all works!
Thanks!
no expert here either... but my understanding is that all of your heat transfer is complete after approx 30 feet of travel ..so if you have a continuous "snake" you are not getting any value out of the tubing after the 30 feet
That is increasingly our understanding as well. Ours ended up being about 40+ feet, so a little longer than ideal, but hope it will work effectively enough.
Tom, check out this site - it has a lot of great information about these systems: www.ecosystems-design.com/faq.html
Great job! What state are you in?
Thanks!

I would like to see more then hear more🤷🏼♀️
We're sorry. We're not professional creators. Hope the rest of your day is better. God bless!
I have checked out several of your Geothermal Greenhouse videos on 5 computers at different locations and it is always the same issue - for some unknown reason your voice is too low for me to hear & understand you... I hope you, or I, find the reason and correct it soon -- because I know that you are offering valuable information and I need it !!! Thank you. 06/18/2018
Sorry to hear this. You're unfortunately not the first person to say something about this. Before I upload, I even raise the sound level to just over 300% of original - specifically to make sure folks aren't having issues with sound. Understand you have tried different computers, but have you tried different browsers? Firefox, Google Chrome, etc? Just trying to help problem solve. I can never get this issue to replicate so it is hard for me to figure out.
Hi...ok so you didnt say what kind of lumber that is....just an fyi dont ever use treated lumber anywhere near where you grow plants for food.
For some reason, your audio is faint. I cant turn up my volume enough to get good sound.
That sure looks like a narrow door way.
Its a lot easier to CUT all the tree's down then move the green house or garden 🤔 😕 😐
You enjoy talking a lot, 😁😁
Yes, sometimes, but not always. I think of it as exercising the freedom won at the expense of many brave American men and women's lives. God bless.
Stop talking on your videos and show more what you do
We'll never understand people posting comments like this on our videos. We create and post something that is free to watch and we hope will be helpful for at least one person out there, and then get a comment like this. You always have the option of not watching any of our videos and only watch other videos without talking. Free will, it's a beautiful thing. God bless!
