Summer weather is straight up kicking my ass right now by raising my grow room temperatures 90+ degrees, I know that with these kind of temperatures hydro can be futile which is why I've decided to go with an all soil grow. Do you think think that my plants will be able to survive through 90+ degree days, or am I better off just waiting for the fall season?

depending on strain its possible for veg if u have plenty air flow but i would say that is much too high for flowering.. are u using any ventilation? air cooled hood?

Yup, air cooled hood, 6 inch inline connected to it, I also have a separate 3 inch inline fan bringing fresh air in (I've heard passive intake would be just as effective, but I had an extra 3 inch inline lying around, so what the eh?) I also have 2 oscillating fans on 24/7

Try changing your light cycle so it is on at night. With a window fan blowing into the room, a 2x2x5 tent running 400 watt hps open air reflector with a 4 inch inline exhaust and dual 4 inch passive intakes runs between 75 and 80 degrees.

I have a similar setup and had Hermies from the heat. A window AC and the nightime 12/12 makes all the dif. The central air in the house couldn't do it. Here in the Mid-Atlantic region the heat and humidity get real bad. The window AC costs about $100 bucks. Much cheapeer than the loss of a crop due to seeds.

There's a guy on another forum that grows in high heat. Right now he's at 110 and the plants are holding off from flowering but he does it all the time. Is it ok to show his thread addy here or will the mods get upset?

here's one of mine:https://www.rollitup.org/indoor-growing/435380-growing-high-temps-possible-85-a.html

my last grow had consistent temps in the 100's, I would say that yeild suffered slightly but I was able to get them all the way to harvest. I say if you got the time and space might as well try. Good luck
