Hi dave saw your greenhouse looks so awesome but i have one better.My kids build us a pond last year as a wedding gift, and we enjoy it allot. As winter was coming we got concerned about keeping the pond from freezing. So i went on line and found a site for constucting a dome cover from ponds. Actually we modified it and make a greenhouse instead. It covers the pond completly and adds another 6ft in the back for the flower garden and falls. And not only did the pond not freeze, but the roses were flowering in late feb. How cool is that.Now that summer is coming may just keep it up , may stop the cats, coons, squirrels from killing my plants and koi. What ya think?
Sry no picks but stay in touch and they will be posted on my website in the next few weeks.

Jim, it’s hard to say. It’s not too uncommon to have gusts of 50-60km/h around here.

Very nicely done. What is the highest wind velocity that your greenhouse has to handle there in Alberta?

Here is my plastic update: All is bright and well! The plastic looks the same today as when I put it up – though just a smidge dirtier…

this is really nice Dave, a simple, doable, affordable greenhouse for everybody, but I have to ask how your plastic is holding up – have you had to replace it yet? Every year I have to hunt down the pieces that blow out of my aluminum frame, plastic panel greenhouse and try to make them stick another year….its gotten really tiresome, but hopefully this fall, we’ll be able to put up one similar to yours…thank-you for the inspiration.

Great design. Have you thought about incorporating misters /sprinklers into the pvc.I think it would also help with the wind problem as it would weigh it down.

I think I would personally go with the solar. I don’t know if I’d bother with the tubing though – I might just go with black drums of water.

I live in N.E. Ga and had a hoop greenhouse. I am getting ready to build another for early and late veggies. Two methods I am looking at to heat it is 1. Passive solar using black tubing outside and 55 gal drums inside. circulate the solar heated water from the black tubing to the drums inside by natural convection. 2. Dig 24 inches deep inside greenhouse, lay 18 inches manure and 6 inches fill. First method seems best as I do not know what the stench would be from the second. HOW ABOUT SOME COMMENTS.

Oh man, that’s cooking! You’d need some serious ventilation. Blow open the ends of the greenhouse or roll up the sides or install some fans. You may also want to install some misters depending what you’re growing.
