This is my second year with my rooftop greenhouse and due to poor air circulation when I assembled it last year, my plants were plagued with pests and did not do very well. After a year's beating by mother nature, my greenhouse has holes everywhere on all sides, but the door still zips up. Now my greenhouse has wonderful circulation all around and my plants are doing very well. When fall comes around, I plan to replace the housing and manually poke additional holes. Investing about $200 a year by replacing the plastic or even replacing the popup greenhouse is worth it. This is what it looks like now with holes. It's a 12 x 7 x 7 pop up greenhouse that cost about $150. Ever since I poked holes in the smaller one, my Italian Basil is doing great.
to the forum! That's a nice big rooftop greenhouse. Glad to hear your plants are doing better. A greenhouse is a real learning process.
