Green houses are expensive but they can be built with minimum expense compared to the fancier ones and do just as good of a job for a lot less money.
One of the most valuable assets in my garden is my Hoop-Style greenhouse. It has allowed me to grow plants that I normally would not be able to grow, produce crops that the season is not usually long enough to produce, and protect my plants from frosts, hail, or other severe weather that normally would have destroyed my garden.
But I don’t have thousands of dollars to spend on a greenhouse. I just priced out an 8’x12’ greenhouse for $3,500. I would love to have a large, professional greenhouse, but that simply isn’t financially feasible for me. So, instead I’ve found a way to make a large greenhouse that is functional, easy to build, and inexpensive. This article will explain to you exactly how to build a 12’x32’ hoop-style greenhouse for under $400.
Required Materials List
Note: All wood should be green, treated wood to resist rot. (Or you can spend more money and buy a rot resistant type of lumber such as cedar.)
- (4) 2×6 – 16’
- (2) 2×6 – 12’
- (14) 2×4 – 12’
- (19) ¾” x 20’white pvc pipe
- (9) 10mm x 10’ rebar
- (1) 20’x50’ roll of 6mm plastic
- (1) Bundle of 50 4’ wood lathe (or optional staples)
- Zip ties
- Nails or screws
- Metal banding
- Door hinges and handles
Step 1 – Laying Out the Frame
Using the 2x6s, lay out and put together your 12’x32’ frame. (You can join the two 16’ pieces with a 2’ piece of 2×4.)
Ensure that the frame is square by measuring diagonally across it. You can temporarily keep the frame in place by pounding a 30” piece of rebar in each corner. (You can pull these out to use them in the next step.)
