Of course i'm looking for the best deal for the plastic. I'm wanting to order next week. I did a search and found almost nothing on where y'all are buying this.
I was reading how much the heat of summer diminishes the life of the plastic and how people new to greenhouses don't take venting seriously enough. I'm planning on auto venting and thermostat controlled fan but it seems like a good idea to just take the plastic off for the 4 months of summer in Arkansas. Its hot and dry here and i see no benefit to covering in the summer. Nights will always be in 70s if not higher, days almost always 90s unless more. Originally i though to roll up one side in summer.
So if ya take your plastic off have you an easy way to keep it in place and put back? I've got 1in PVC frame. I bought one piece of 1 1/4 schedule 40 and cut some pieces about a foot. I have a milling machine so i machined an opening about 1in (if i remember right) so the 1 1/4 will snap over the 1in PVC. Now I'm thinking of taking a piece of 1 1/4 and slicing in half lengthwise and seeing how that works to keep plastic tight and in place.

I think you will do more damage to the plastic taking it on and off each year than you will save. It's a consumable, I don't see any way around it.

We did a roll-up door assembly. It is working well so far. I will put in sweet potatoes in the summer and call the heat a blessing. But the hens will be moving out soon before it gets too hot.

When I had a small greenhouse on my old place in GA, I'd get three years out of my plastic by just this method....taking it down in the warm months. It was a vary ramshackle greenhouse....frame of bent saplings and plastic weighed down along the edges with logs and bricks, tied to the frame where needed by tucks in the edges of the plastic around rocks or nuts (this is a wonderfully strong tie, and better than grommets on a tarp).
What's more, if I was short of money, I'd scrounge new plastic. Mattress and furniture store dumpsters.....these things are shipped in huge plastic bags which can be opened up and trimmed into large square or rectangular pieces which can then be "candle welded" into any size you want. There was so much I could afford to be picky and trim out or reject any with lots of holes; a few small holes I would patch with clear packing tape. I would always put two layers on the frame, and then just fold it all up and stick it in a box for the summer....
Maybe not the most attractive, but it achieved it's purpose.

Maybe i'll got searching for some free. Furniture store just down the street. I have about 50 strips of steel. 1/4 x 1/4 by 8 foot. I've been thinking to bend it and cover with plastic to get my greens started faster. I could use this free plastic. Now I'm waiting for about 1in of ice and crystallized snow to thaw. I did go and buy "polyfasteners" which hopefully will make taking down the greenhouse plastic easy. 3 months min its just too hot here.

We left it on, but covered with shade cloth.

Rosco, these guys are in Denver but sometimes they find stuff in other areas. Might be worth an e-mail to find out.

Or if you have trucking firms or railroads near you, that use this stuff.

I got mine from a company called Mr. Shrikwrap. This plastic seems just like standard plastic, but when you heat it, it shrinks to give you a nice tight fit. Probably wouldnt work for takeing it on and off. But because it fits so tightly the wind doesnt damage it like normal plastic. I have only just gotten mine, but the guy who turned me on to it says he gets 5-6 years out of his because it fits si tight the wind cant tear it up. It was origianally made to store boats over the winter, so there is a lot of info on it if you search boat shrink wrap. Good luck
