Costco Carport Greenhouse. This frame has 8 legs measures 10 feet wide 20 feet long with a peak height of 9 foot 2 inches. I used the frame only from a 10x20 Costco carport.
This thing is huge you could literally drive a truck inside stealthy. On Amazon they also have sim. We decided to beef up this one by attaching the bottom of the posts to some pressure treated 2X6 boards.
Make a carport greenhouse with your carport frame size 1020 to 3040 and our clear poly covers.
Whatever your budget whatever your space Costco has a greenhouse to fit your need. The weatherproof aluminum frame will. We purchased it for 50.
