hey Hondo those girls are looking great , Last year I set up my green house and moved everything in ,even though I could and did raise and lower sides once it got warm I was battling heat and humidity all summer long so this year I did not put the cover on ,I'm just letting you know what it was like all summer .I do have plans to cover it in September in case of a frost . I know GH like your probably have tops that will open to get the heat out .good luck
