controlling air temp??

[Eikes1390]

I have three different tents in my basement and as a result the air temp is rather high even outside the tents and I have a problem with it being too warm, about 80-85 degrees. I would ideally like to be around 72-76 but all the air in my basement is warm especially with how hot it has been this summer. BESIDES a window unit, is there any type of ac unit or cooling idea that I could use that would help maintain a lower temperature?

80-85 with the lights on is not bad at all.. might not be 'perfect' but I've lived with worse. If anything I'd suggest looking it to co2 enrichment. You seem to have the perfect setup for it. It's better to be a little warmer when using co2 anyways.

ice or cold water in a bucket/s. 80 is ok (lights on) but you want a 10* drop at night (lights out)
