Hey fatherearth I have 4 carport greenhouses. Three of them have 3 200 gal plants and 1 extra big carport has 6 100 gal plants. And I have one hard plastic greenhouse that is leaned up against my barn.
I built this greenhouse by converting a 10'x20' Costco carport into a greenhouse. most things in the greenhouse are in 5 gallon smart pots there are 4 that are in 30 gallon smart pots that are nice and tall.
