Plastic degrades and breaks up. What a pain to clean up. Six ml Greenhouse poly should last at least four years.
This is a lesson in what not to do. The roof isn't steep enough so snow doesn't slide off well. It's poly and sags a little over time so snow builds up at the bottom. I'm going to take it off before I use it this spring and cover it with polycarbonate.

These are fabulous!
Many are much more adventurous than I'm ready to take on, but I love them!

Awesome. What happened to Zong's photos? I saw part of them and then it turned all black? I liked that one. Can you fix the photos?

Here is the design I followed:
Cheap and easy greenhouse just like it says
Mine is 24X15 and cost about $450. $150 for the poly, $120 for the PVC, $100 for rebar, and $80 for lumber, wire, and miscellaneous. Probably could have built it cheaper if I shopped around more for PVC and rebar.
I follow the design in link above exactly except for adding a double 2X6 beam across the top with one support in the middle. Without this beam I would not trust this greenhouse to hold up to any more than a a couple inches of snow. But with the beam its taken two feet of snow and not budged an inch.
A few pictures of my greenhouse.
I can post more shots of hte structure if anyone is interested.

Here is mine. But, in TX it is much too hot for the 6mil plastic and it really breaks down fast. I find that I have to replace it every year. I really need to put up some of the clear fiberglass.

Rose, not sure what you mean? The first link should take you to
http://www.laspilitas.com/garden/howto/greenhouse.html
and the second link (pictures of my setup) should be for
http://picasaweb.google.com/brian.from.ct
are you not getting to either of those?
Also I guess my setup is not truly a "greenhouse" since its unheated, but a high tunnel. I may throw a heater in there someday for spring time seed starting (to keep the overnight lows up a bit), but heating all the way through the winter....dont have any plans for that but there is no reason you couldnt do it with this setup.

Thank you Zong - I see them now. Looks great. I have a pile of old windows and I think I can build one. Thank you.

What do you think? Convert or build? I could take the tin of the lean to and change it to clear.
|
Just my opinion...I'd convert, so you can get your greenhouse done faster & structurally sound enough to bear the weight of snow. Also, since we get high winds here, my greenhouse (the kit) will have steel reinforcement. DH built me a garden cabin to do double-duty, but we should have used clear roofing over more of it. As it is, however, great for starts & housing plants over the Winter. The interior will be insulated/heated and finished when it comes up under "priority projects." I'll see if I have a recent picture. The projects ahead of it? Finishing the system to use our wood stove to heat our water (that should be done by Tuesday). Installing the bamboo flooring in my enclosed porch (DH just completed it). I scored the flooring off Craigslist last year. Then, my little greenhouse kit (DH is putting it on a foundation, raising the height, and also building some steel reinforcement). I don't know if the garden cabin will hit the top of the list until Spring, maybe...

Here is a recent picture of the garden cabin. The greenhouse will be built near it.
The closest side is the tool shed side (10 X 7) & there is a deck that wraps around (we keep firewood behind it/attached wood shed up to 5 cords). The other side is my side, which is 10 X 13 with a loft over the tool shed side. The only windows we had to buy were the diamond ones; the rest were all free & double paned. We used sliding glass doors for the large windows at either end (the one on the closest side is yet to be installed). All the siding was rough hewn Cedar and given to us by a retired logger up the road. We still have some finish work to do. The larger entry closest will be dual barn style doors DH will be building.

Your sleeping well at night ends when you put your first frost sensitive plants in your greenhouse. Too hot in summer and live in fear of running out of propane in the greenhouse in winter. Always something to worry about. Mine is 12 by 16 and about 10 feet high (for hanging plants). Last night it got to 11 degrees outside and with propane heater on at 15,000 BTU per hour (high) it kept it about 34 degrees inside. Burns about a full BBQ tank of propane on high for 24 hours. On cold nights, always start with a fresh propane tank - ask me how I know.

I just have a hoop house made with cattle panels tacked into a 4 x 4 frame at the base. Its 10 x 14 and nearly 6 feet at the center. I use it pretty much as a cold frame and I have some guinea keets in there now over winter. In the summer I remove the plastic and grow vine crops on it. Here it is last summer covered in butternut squash.
Now if my husband was handy, I can get a bunch of old windows.........

great greenhouses everyone...I have greenhouse envy. Some friends of ours had a tree fall on their solarium this winter and they are giving us the framework. There are only a few windows missing so I am hoping to either cover with poly or try to find some used windows somewhere. I can't wait!
