I'm with you on that one, I live in SoCal, and I don't have AC, so with temps topping 100+ here in the summer, I'm DEFINATELY shutting down the DWC for the summer, but I'm thinking soil plants will be ok...Just the water in hydro gets too hot for the roots in summer, causes root rot and shit like that. And if my little indoor soil plants are a little stunty because the temps are constantly in the 90's, then so be it! Haha, they're gonna have to deal with it, i'll just give them nice cool drinks of water more frequently...plus I have my little DIY AC unit I made out of a styrofoam cooler and a couple PC fans, so I'll put some frozen water bottles and dry ice(to keep water bottles frozen longer) in there to hopefully bring temps down...I hope you continue to grow indoors as well as outdoors, just remember I'm in the same boat as you, no AC and soaring summer temps...we'll get through it together
