greenhouses too hot for summer use?

[george]

hey ron, george in crescent city fl.you were right about greenhouses are too hot for summer use here in fl. using 70% shade cloth, 2 roof turbines, 2 exhaust fans & a small swampcooler still had temps in the 90's.i threw in the towel & moved 2 of the hydro units outside. peppers & tomatoes are alive but almost no growth. my question is for outside use in this heat does the nuit. solution need to be cooled for good growth or should i just forget about summer hydroponics & go fishing?

My peppers on my back porch are also suffering because of the heat. I don't think they will make it to maturity because it ain't even august yet the hottest month.
I don't think cooling the solution will help that much.
My Heat Wave tomatoes in my pool garden are starting to bloom but I have to let the garden drip continuously during the hot part of the day.
I'm just going to get my commercial garden ready for this autumns growing season.
