We got the Farm House model for $315 delivered from Home Depot. 8 X 8 Went up in 2 hours. The condensation is a concern because of possible damping off...
I greatly alleviated my condensation problem by unzipping one of the lower windows just a bit. It was bugging me too and I lost some basil seedlings to damping off.
I open my upper windows during the day but the night time condensate was a killer. When I first thought of it, I unzipped a window on the south side all across the bottom and halfway up each side. I didn’t velcro it, I just left it loose.
I left it like that night and day for a few days till we were supposed to have a freezing night. It was just supposed to drop to 32 that night but I went ahead and zipped that window down both sides but left the bottom horizontally unzipped for the light freeze. It was fine.
The only nights since then that I’ve zipped that one all the way up is the last 3 nights when we’ve been down in the 20’s. It seems to have done away with my problem. Although, after 2 wet days and having that part zipped there was a LOT of condensate this morning.
I didn’t do but one lower window that way because it took care of my condensation. If you needed to you could always do a little more and get some cross-ventilation.
Just my $.02. Hope it helps.
