Small grow tent is too hot?

i think you are moving enough air, so that won't impact it more than you already do. more efficient lights more space had some initial heat issues in 3x3x70 tent with soem inefficient lighting. Moved those lights into a larger box with ~20" more height and more volume of air in general and that eliminated the problem. Replaced the lights with efficient LED and now i have cold temp issues in winter, lol... both of these tactics work well.. unfortunately they likely cost money. evaporative coolers might help a few degrees, and raise humidity, if that's not a problem. those are fairly inexpensive but not too effective. if you can duct some cool air into tent or place an ac inside it, you are limited. can you cool the room itself, if small enough?

You can try ice cubes..
