Cooling

[davduggie13]

Ive got a small room, Ive got 3 - 600 w lights. when running 2, temps are too high 85-90'
Does anybody know of a way to cool down. Ive thought of ac, but I don't have a window to vent hot air out. I could use a portable ac unit and vent into attic, maybe, I'm thinking an evaporation unit, but Im not for sure about the humidity?

anybody have this experience?

Thanks and Peace Be with You!!

Be reminding yourself, ventilation is key, especially if you don't have a CO2 generator. Even idle air will create hotspots, fans are friends.

Imo, your best bet is to invest in a chiller based fan. It wouldn't be anywhere near the running cost of an AC unit, and, would probably be a similar initial setup cost. I.e, to say, a fan with a chiller. I believe Greners and what not sell them titled as "Ice Boxes" 6", 8" what not.
