m0useanswered grow question 2 months ago Ice, just toss it everywhere inside the tent, on the lights, on the plants, on the floor, inside the extractor fan. If its not making a tumbling sounds like a blender your doing it wrong. lol
Just kidding.
AC is the best way, or running an opposite lighting schedule, lights on at night and off during the day to help avoid heat spikes.
Keep up the air exchange so outside temps match the tents inside temps, normally my tent runs 2-5c warmer then ambient temps in the room, but if I ran my fan higher it would be even.
Good Luck!
