i was think about this while i was high a bit back...its just a threoy...so here it goes...

if ur grow room is relativly small, then u could freeze bottles of water, or even gallons if need be...have 1 set out in the grow room cool it down and have another set in the freezer and just alternate the 2 so ull always have 1 in the grow room and 1 set in the freezer...im nto sure if itll work but its feels like a good idea, i dunno maybe im just really high
