Building a Planta Greenhouse | The Foundation (Part 1)
Вставка
- Опубліковано 24 жов 2022
- We are building a 10' x 26' Planta Sungrow Greenhouse and have been working on a proper base. In this first video about our greenhouse, I'll talk about the lead up to getting it and how important the foundation is to make sure it's best fitted from the start.

great start and great explanation of doing it the way you did.
Many thanks. Video later this week - I have the framework up!
Drill a pilot hole for your lag screws, use a bar of soap on your screw threads when screwing them in.
I really appreciate this advice. I will do it! I thought it might be a knot in the wood I couldn't see and didn't want to force it in. The soap is brilliant. Many thanks.
I just purchased the Sungrow Urban 10x13. Live Alberta Canada in the foothills of Rocky Mountains. Looking forward to building it in the spring. They will store it until April before delivering. Looking forward to building it!
Happy for you guys. You will not regret the purchase. It is a game changer.
Well done Mister. I'm about to embark on the same project and watching really helps me visualize the process. Cheers!
Thank you for your kind words. It is an adventure. Stay open-minded. It is a decision I have not regretted one day. Have a great week.
i did six 8 inch diameter concrete pillars going down 4ft with simpson strong tie 5/8 bolts embedded a foot in concrete leaving like 7" sticking out. I square notched the ends of my 6x6s then drilled through and bolted them onto concrete. It's michigan weather and frost line will heave it otherwise.
I like your plan. Not that cold here in Alabama and I’m thankful. Hope you enjoy yours as much as I do. Happy holidays.
I had the same problem using lag bolts to tie down for a garden border but they do make 8 inch and 10 inch galvanized nails for that purpose to drive all the way through
Great idea. Wish I would have thought of that at the time. Thanks for the feedback. Have a great week.
Thanks for the great video. Our new Planta 10x26 arrives in two week and I have levelled a section of dirt (red clay here in VA) for the greenhouse. I was originally going to get a truckload of crusher run in and put the greenhouse on that, but your wooden foundation seems better. My question is, did you attach the wood to the ground at all, or are you dependent on the weight of the wood to keep the greenhouse in place in strong winds and storms?
Great question. I’m a Virginian living in Alabama so always good to hear from someone in the commonwealth. I did not attach the greenhouse to the ground. The Planta frame is strong and when it gets all locked together you will be amazed how tight the structure is. The greenhouse will be ripped off the wood before the wood moves. It’s heavy. We have had some strong winds ( up to 50mph ) since I built it and no problems at all. Reach out if you have any questions when you get started. I’ll be glad to help. Thanks again for the question.
Thanks for great video, I’m getting ready to put my 10 x 20’ Sungrow up and foundation info is sketchy. I’m just wondering what your climate is like. We are in northern Ontario and frost heaving can be an issue. Local hardware store said do the crushed like you did then half bury concrete block around perimeter (no cement used) then glue 6 x 6s to block foundation ( glue ? sounds strange). So I bought all that but thanks to your video I’m definitely going to add 2x6s to help hold 6 x 6s together.
Thank you for the reply and kind words. I think you would be okay with how I did it with the exception of maybe burying the water line deeper. I am working to build dirt up and around the greenhouse base for extra insulation. Not a lot, but definitely up to the wood to cover all of the crushed stone. I also put a suffice amount of pea gravel on the inside.
Hardware store sounds to me to be trying to sell you more materials. GLUE?? Interesting.
Thank you again for the question.

Just purchased a Planta 10'x 13' for April delivery. Researching foundations but going with gravel base and 4"of concrete. I like the extra height with timbers but will anchor them to base. Good information.
Thanks. Gravel will do you well. I am currently looking at putting pea gravel over my foundation gravel for a smoother look. Thanks for the feedback
Hey there! I just purchased a 20’ sigma and I was just about to go at the exact same foundation you built. I was wondering if you built the frame EXACT to the dimensions they provide. I spoke with planta about it and they suggested adding .5 inches to my frame on the end and an additional 3 inches on the length. I was wondering what you did? I’m concerned about it being a bit too wide and having my tie downs end up being splayed out and not exactly flush. Thanks for this video!!
Great question. I built exactly to instructions. Didn’t add anything. Here is a major suggestion. Make sure all your 6x6 have perfect corners on the top side. If not then there will be a gap when the polycarbonate over laps the wood. It’s not a huge deal but I wish I would have known. I just pushed some foam rubber down into the gap and it is fine. Good luck. I’ll be doing a video in the near future on what I would change after the one year mark.
I'm enjoying the videos as I purchased a Sungrow 32 and looking forward to installing the greenhouse here in Ontario, Canada. In speaking to the Planta Representative they also advised that the width has to be exact. That exact measurement, they advised, was 9' 10 1/4". In your video you mentioned 10' which would be a difference of 1 3/4" difference. That 1 3/4" difference would affect the frame sitting exactly on the edge of 6" x 6" which I am also using.
I watched Planta's video which described the width being exactly 118.1" (9' 10 1/4" or 300cms). Am curious if your measurement was less than 10' or was it exactly 10'. Trying to make sure my cuts are exact and looking for feedback. Thank-you
Thank you for the question - I did exactly 10 feet. When working with boards as big as 6 x 6 I cannot stress with the exact 1/8th of an inch to be perfect. That extra was distributed evenly on both sides and made a small "lip" at the bottom that allowed the polycarbonite to have a small amount of bend.
Im sure you are a better carpenter than me and if you are, I suggest cutting exactly as they say. I just didn't have the skills to do it.
I hope this helps. You will love the greenhouse.
@@StewartFarmApiary Thank you got the reply and will try to remember to let you know how I did. You’re right about extra costs which, after the unit, is for the foundation.
Tomorrow, I’m ready to lay the 6x6
hello friend. if you have time can you tell me what size l-brackets you used on the inside corners of the 6'x6's? also what type of screws and size of them did you use? and what is the name of the plates that you used to bind the 6x6's together lengthwise? great videos , very big help
Happy to hear the video is helpful. They are 12” brackets that are bent, so 6” on each side of bend. I used a heavy grade 2” bolt to screw in. Nothing complicated - I knew I wanted 2” minimal and when I got the brackets I just went to the bolt department and found ones that don’t the holes firmly. Tractor Supply Company or Lowe’s will have them. I got mine at Tractor Supply.
I did not use plates to bind them together. I just offset them on the 2x6 and screwed in with 3” deck screws ( lots of them) on the 2x6 side. Once they are all screwed in it is very secure.
@@StewartFarmApiary i don't know where i got the plates idea from, must be another video. thank you, i hope you don't mind answering questions months after making your video
@@zakkrueck2362 Not at all - that is how we all learn from each other. I'll always answer any questions I can.
Was additional height the only reason for using the crush and run? I’m trying to figure all of this out and I have watched your series on building the greenhouse. I was wondering if using just the 6x6’s is all that needs to be used for the frame or if the 2x6’s and the crush and run is required.
Great questions. A lot depends on your soil. I used the crush and run because it sets up almost like concrete once it’s packed down. I wanted a solid base for the 6x6. The 2x6 have a main purpose of holding the 6x6 together and not allowing the seams for bend where they join. As the wood gets wet and then dries it tends to warp a little and this ensures minimal warping. My main concern if not using the crush and run is the greenhouse “ settling” and then you will have issues. The height is nice also. This spring I am growing indeterminate tomatoes and I will string them up with little worry of the height.
Watch later this week - I will be releasing a video on the unexpected costs of a greenhouse. I am sure you will find very helpful of you are looking to buy one.
Thanks again for the question.
@@StewartFarmApiary thanks for your reply. I look forward to seeing your next video.
Hi, I enjoyed the video. I was wondering on the base what the exact measurement was for the width? I'm using 6x6 as well. However, mine is a 20-foot greenhouse.
Is your greenhouse a Planta? The measurements for mine is ten feet wide.
Yes, it is a planta. When I called them, their tech said the width in fraction was 9'10 1/4". Today, I decided to pick up a 7.5m (25') tape measure. 300cm = 118 1/8".
I will say the idea of using the 2x6's is a good one. I'll be using the same. Thx for the info.
@@pawpawchronicles-n-morewit1210 Yes - which when I measured out is basically 10' wide.
@@pawpawchronicles-n-morewit1210 Yes.
Thanks so much for posting this! I am confused though. In your video, you emphasized that the width should be exactly 10', but their recommended foundation width is 118.5". Does it matter?
I called and spoke to them when I did it. It’s only 1.5 inches difference and the frames allow for a little give. Mine was perfect and I have zero issues. It was also so much easier to leave at 10’ instead of having to cut a massive 6x6 and keep it exact. If you are worried then I suggest you go off of what they say but I don’t have any issues. Thanks for the question. I hope my answer helps.
@StewartFarmApiary thank you so much for your quick reply! I am relieved that I don't have to shave 1.5" off these 6x6's!!
@@paulstuart5077 Glad to help. I have a few more videos on building the structure that may help too. Be sure to check them out on my page. Have a great week.
Is the gravel just on top of dirt or did you dig a trench that you poured gravel into?
Just on top but tapped down and packed.
Use some bar soap as lube on the screw.
Great idea. Next time I will for sure. Thanks for the suggestion. I hope you have a great week
I moving out of Englewood Colorado, to Southern rockies of Colorado. Want to raise fish and do auquponics ?? Hydroponics?? Tired of eating poison food from big corporations who are hell bent on killing us all
Best of luck with your journey!!
I would have seemed up the corners, like you did the long timbers. Overlap the 6x6's with 2+6.s. Otherwise good work.
Thanks
Did you use pressure treated for 6x6 and 2x6
I did - pressure treated wood today is not used with the same chemicals as years ago. I have checked with two u universities with outstanding horticultural programs that have told me this. I hope this helps
What was your exact measurements? We are getting a 20 foot long, but the width should still be the same.
@@knagjak If you are building a Planta greenhouse then it should be 10" if it is the same model as mine. I hope this helps. Mine is a 26' x 10'
Should have offset the seams so they weren't in the same spot on the left and right.
This is holding up so far - is that how you built the foundation for your greenhouse?
Yes. It will probably hold because it is over-engineered. But for additional structural strength, the offset is a good idea.@@StewartFarmApiary
