Laminate several thin layers of exterior grade plywood around d the curve. I used 1x4s and cut them about 2 foot long staggered them around the curve in 2 layers.
I love the hoop house and it gave me some ideas. If I may add a bit of advice: Instead of trying to curve 2X4s, I would use several layers of 3/8 inch plywood. Cut and attach each strip one at a time and glue between each layer. I've used this technique when making skirts for round table tops.
Thank you for the suggestion. This has been suggested before as well. I stayed away from plywood for this project because it is outside in the elements. I was afraid of delamination in the plywood due to the moisture, high UV, and significant temperature changes. The thin strips of pressure treated 2x4s worked well and with the weather resistant glue I was not as worried about delamination.
Sorry to Necro this but I'm in the planning process of doing exactly this as I've inherited a large hoop house like 25x50 that needs new plastic. The frame is all galvanized steel like commercial greenhouses but I would like to do these polycarbonate panels like you did for aesthetic because wife and the curves on the side have had me stumped. Did you just resaw treated 2x4s to thin malleable strips to do the lamentations on the curves? Again sorry for the Necro post but your video is literally the only video I can find that uses these panels on a curved top greenhouse like mine. Thank you
Those curves are a monster. What I did for my greenhouse is I bought a 4x8 sheet of beadboard paneling which is about 3/8" thick, ripped it into 3-1/2" strips lengthwise. Then I used a table saw with a sled, and took an 8p nail (which is the width of the blade) and made an indexing pin about 2" from the blade, and I set the height to be about 1/4" to make grooves into the "bead" side, 2/3 of the thickness of the boards, and made kerf cuts along each piece. These are extremely flexible now and have to be carried on edge. Since my hoop house uses 16' panels, two 8' pieces make a full circuit with very minor trimming. These are held in place against the inside of the panels with spring clamps (I used about 20 of them) to meet end-on in the middle (top) of the greenhouse, then wet the wood and used gorilla (PU) glue to laminate another piece of beadboard strip inside, straddling the seam and securing them with the spring clamps (use rubber gloves -- that PU glue is nasty). The remaining 8' piece can be cut in half and fit/wet/glued/clamped into each side. I let it dry for about 4 hours, then moved on to the next one. Each of these "ribs" takes 4 8' strips of the kerfed beadboard, and the two laminated pieces comes out to just over 3/4" thick. Once the glue dried, I attached them to the cattle panels using zip ties. I drilled from the outside using the bars of the panels as the guide, 4 holes (two above and two below), fed the zip ties from the below, and over the top of the "bar" of the cattle and back below where they are fastened and trimmed. This became a tedious job with 23 points (bars on the panel) and 2 ties per point -- drill (x92), feed (x46), pull (x46), feed (x46), pull (x46), zip (x46), tighten (x46) and trim (x46). I found that doing each of those tasks in order (instead of trying to drill and fasten each zip tie one at a time) saved a lot of time.
That is great. We stayed away from anything that was already glued (chip board, plywood, MDF, HDF, etc.) due to the very high UV and moisture. I had thought about zip ties, but ultimately decided against them again because of the high UV.
I like your approach. When I built mine, I used clear for the top. It gets HOT !!!! Using white on the top part and clear on sides could control it better. Just a thought !!!!!!!!!!!!
We finished it near the end of the season. It did get really warm on the sunny days. Our tomatoes loved it. By adjusting how open the doors are we were going to control the heat.
That's a really nice addition...the corrugated panels! I would say you need some ventilation except in the very cold months, but maybe in your climate you don't?
We really did not need much ventilation. During the heat of the summer we would prop open both doors with a scrap piece of 2x4 during the heat of the day and that was enough. We didn't even need air conditioning in the house up there.
Nice Job! You sure have a lot of patience. Absolutely nothing wrong with the way you did it, but just one thing you may be able to do on a future project. Use thin pieces of plywood (1/4") to bend to that angle you want and just keep laminating them togethor with glue and overlap the seams.
That is essentially what we ended up doing but with pressure treated boards cut into strips. My concern with the plywood is getting delamination due to the extreme temperature shifts, moisture, and high UV.
I am in zone 6a. I moved my green stalk that is planted with strawberries into my unheated green house. They are flowering and fruiting . Not a large harvest, but it is a pleasant surprise. The tomato that I moved in did not fruit although it bloomed. Lettuce and spinach planted in ground in the greenhouse are the best looking plants I have ever had. Just in case you are looking for some additional ideas.
Some tomato varieties need pollinators to produce fruit. If there are no pollinators you could take a small clean paint brush and touch the flowers and spread the pollen from flower to flower.
That 2nd attempt was oh so close. Had you simply used an inner, and outer strip separated by spacers every few inches, perhaps 12", you'd have licked your problem with less material and a much lighter structure. Still, thank you for sharing your experience.

How long it took you wasn't six months. Actual time involved not time that transpired unrelated. I built many model railroads over the decades and would hear pele on UA-cam saying it took X amount of years but I would do similar and track my time. Often, what is six months is really a week or two. When you plan ahead and get prepped to actually go at it you will be surprised how time flies and much quicker things get done. Nice job, enjoy vids of people who garden. Connect with nature, live out of the cities etc. God bless, be safe and enjoy.
Soaking the boards (especially in hot water) makes them much easier to bend, but a better method is to use multiple thinner boars that easily bend and then you just add several layers.
Also, those plastic panels will last a lot longer if you paint the wood behind them white. Darker backdrops tend to cause it to become brittle and chip apart.
Initially we just attached them at the ends to the laminates arches and the top of the door frames. That worked well enough for most of the time. Once we had a bigger wind storm, we made some wood blocks about 6-8" long with grooves that interfaced with the wires of the cattle panel. The blocks went inside the hoop house and gave us something to screw into. This sandwiched the cattle panel between the polycarbonate panel and the wood block.
Just to let you know I put in a plug, and linked to your Greenhouse design on my latest video Very well done. I might build my next one like yours... and pick your brain for advice.
Thanks for the plug! Mama Bear and I were just talking last night about improvements that we might make to this design since we are starting over here in WA. Let us know if there is anything we can help with on your build.
Best of best idea. 저렴하고 햇빛이 가장 많이 들어오고 1달 먼저 씨뿌리면 벌레도 없고 더 연한 채소라서 상추와 열무씨를 뿌려서 열무물김치 해보세요.고추가루 안넣어도 맛있어요.온실그린하우스에서 지금 열무와 얼갈이배추씨를뿌리세요. 씨앗 저온처리하셔서...아쉬운건 천정을 통째로 열어서 환기할수있었으면
Yes, 1x4 probably would have been easier. In the end I was really happy with the way the laminated curves worked out. I would probably do it that way again in the future.
In my shop we never used water. Sometimes steam, but usually just dry heat. The steam is actually a good heat delivery method, as the wood is never in the steam box long enough to penetrate much more than 1/8 ". Heat softens the lignin binders in the wood, making the fibers able to slide past each other. The steam makes it possible to heat long/large pieces of wood more evenly and faster than you could in any other way.
Yes, the birds are bad, but the primary purpose of the netting was for the hawks. We let the chickens roam the garden and there are a lot of hawks around looking for an easy meal. I am certain that we lost at least one cat to the hawks.
Hello, I’d like to build a greenhouse using the poly panels and would like to know if you are in Colorado? Will it hold up to a snow load and panels shed snow?
We were in Colorado when we built this greenhouse. The cattle panels that we used were very sturdy and had a lot of support, so they would carry a sizeable snow load. The panels do not shed snow very well, since the ridges of the poly panels are going in a horizontal direction and not a vertical. We made one side of the house lower than the other so it sheds water pretty well, but not snow. Using the back side of a garden rake worked well to knock the snow off without damaging the poly panels.
i will share this with hubs, but i think you might need to get some ventilation ? are the poly panels the best see throughs you can find without going to glass?
For ventilation we were just propping the doors open. Even in the summer, the nights will get down in the 50s, so we didn't want a ventilation that was constantly open or difficult to manage. These were the clearest panels that I could find without going to glass or a solid plastic pane.
I really like what you did since the polycarbonate sheets will certainly last longer than plastic sheeting. My only concern with this design is connecting one sheet to the other across the span. Are the polycarbonate sheets nailed only on the ends? Did you use anything (eg clear liquid nails) to attach one sheet to the other? I would be concerned with high winds getting under the sheets if they are connected only on the ends. What do you think?
After that video was shot, we came back and did attach the panels along the length and not just at the ends. What we did is take some pressure treated scrapes and cut a groove in the middle of the block. That groove was put on the wire of the cattle panel at the overlap of two polycarbonate sheets. Then we screwed to the block through the sheets sandwiching the wire of the cattle panel between the block and the sheet. Thus we were able to attach the sheets to each other and to the cattle panel at discrete points along the length.
Am getting ready to build this but am wondering how you attached plastic to frame and how did you drill into plastic /meaning was it easy or did it crack the plastic at all?
No, the plastic did not crack and I did two things to help with that. First, I attached the plastic sheets on a warm day so the material was less brittle. Second, I drilled pilot holes through the plastic first then followed it with the screws.
Hi Guys, I am new to your channel, and glad I came across it. I am wanting to build a hoop greenhouse similar to yours. Well it was similar, now I am thinking exactly like yours. Can you give me some dimensions on it? Width and length at the bottoms, and what was the length and width of the cattle panels you used? It's a beautiful greenhouse, great job. I hope you both have a great week and I hope to see you around.
Welcome! Sorry for not replying earlier, we have been out of town. I updated the video description with details of the greenhouse construction. Please let me know if you need any additional info. We are happy to share.
@Chris Peters I think I get what you mean . It is round because the whole hoop house is made from a cattle panel, which is bent to make the green house, when it is bent this makes it round or U shapped There is no way to make a cattle panel square. We made a chicken coop out of two cattle panels. I hope I'm not a complete dork and understood your question right.
Just what I was looking for. I got to replace my cattle panel green house plastic.

Hoop house without plastic sheet that different. Your the first I watch without a plastic sheet.
The plastic sheet degrades too quickly with the UV at 8000 feet. I was looking for something more UV resistant.
Laminate several thin layers of exterior grade plywood around d the curve. I used 1x4s and cut them about 2 foot long staggered them around the curve in 2 layers.
You did an excellent job! This is just what I was looking for. I plan to do more of a hoop house style with polycarbonate sheets as well.

Yes, 1x4 probably would have been easier. In the end I was really happy with the way the laminated curves worked out. I would probably do it that way again in the future.

how are the panels holding up?

I assume the cattle panels are 16' long. What is the width of your greenhouse ? Great job.
The width is just short of 11'. Each bed is just over 4 ' wide and the walkway is 30".

Looks good.How are you ventilating this during the day so you don’t cook your plants?
We prop both doors open and get a pretty good cross breeze. Then in the evening we can easily close the doors to trap in the heat before night.
O man that hurts the feelings my friend

bravo about the curved boards! then i saw they popped. then i saw your persistence ! bravo again for attitude.
i watched alaskan dog sled building. they form a steam house for the boards.
you could use your greenhouse for drying and cold smoking fish and meats
Nice
This is a pretty smart design but won’t the ribs hold water ?
The greenhouse is slopped end to end, so water will run off. Snow will get held and needs to be knocked off on a regular basis to prevent collapse.
How’s your greenhouse holding up with storms or did you do any modifications?
I just saw your video, I like the polycarbonate roofing is your greenhouse 8feet I think it is cause those panels are 2foot by 8 foot
The greenhouse is 12 feet long. Our big box store had the panels in both 8 foot and 12 foot lengths.
I think they soaked the wood in water first then bowed the wood.

How did it do with snow and drainage?
It trapped a lot of heat, so small snows just melted. For larger snows we would have to go and knock it off with a broom.
