@Beautypaste420, thanks for the reply. I'm in Michigan and it has been hitting 90 f here for the past week with very high humidity. Luckily, the plants are all hardened off already. I close it up at night then first thing in the morning, roll the door up. It breathes relatively well in there and surprisingly, no heat stress yet. My greenhouse is positioned so the wind blows through well and it gets shade once the heat of the day starts to roll around. This is a trial run for me to see if it is viable. But I do have some ideas for modifications if it gets bad
