I wanna build a greenhouse

If you live north, get a bunch of double paned glass and aluminum poles as main support. Build a wood frame for more stability if needed. Walls do NOT need to be glass. A cheap plastic, wood, cement, or any material you want is fine.
And lastly, make the roof segment facing south as large as possible, extend is farther down than the North face of the roof.

Harbor Freight has a cheap greenhouse to get you started. I'd start there in case you decide it's not something you're really into, you wouldn't waste a bunch of money.

If u count spending a few grand on lighting and growing supplies to turn my spare bedroom into one then I have. Highly suggest some sort of sprayer so u dont have to bail water all of the fucking time. Quality led grow lights will help trick you olants into thibking its summer while also being energy efficient. And a wood stove will help if its cold where u are. All my shit died and i gave the gear away. Best of luck to u. Ill never fucking garden again. One of the worlds largest greenhouses is in town. They use some sort of plastic for the roof. Its clear and the best description is they buikt a tin roof with it. I dunno. They are fucking jews so i know its cheap. Ill ask them where they get it. Dont wast your money buying harbor frieght shit

What state are you in?

OP you can build a frame really easily with a few aluminum angle irons or some wood molding or something. Additionally try to avoid plastics for the sheeting
