heat co2

Honestly more than anything I would suggest lots of fans, co2 is helpful but not required. 86 degrees can be stressful on the plants you want it under 80 for them to stay healthy and happy.

I went to walmart and picked up 2 $20 box fans for that exact reason. Also have 2 inline fans.

If you can't keep your temps down then 86 is fine when supplementing co2. The most important thing you're handling and that's humidity, I say most important only because plants can surely get thru a little heat stress but who wants to smoke mold. Upper 80s is fine IF you supplement co2.

fans just moving air around in a room don't cool, they actually add to the heat. if the room is sealed and the fan is circulating on the room.

Thanks guys...its a basement grow. Have exhaust fan and. Room fans but my windows sealed so no cool air can get in and the damn dehumidifier is the beast of the heat. Thanks for answering. Guess i will go rig something up. Off to diy youtube. Be eZe

Yes i read all fan will do is blow warm air since i cant bring cool air into the room. Its frustrating as hell

good luck and happy growing.

co2 should be used anyways for faster growth and a bigger yield if you have that option. my room gets up to 90 sometimes and never have issues but i also have good ventilation

Agreed, that's why fresh air from outside is so important. I personally don't use co2 so I can't comment on it, but good ventilation is more important than anything else when growing indoors, even light in my opinion.
