Are your lights cooled?I just put a 24000 btu in a 12x12 with 4 1000 watters. found one on ebay for $1000.
I run 3 1000w OPEN hoods with a 24,000 btu and could probably cool another one no problem. It does not run all the time.Are your lights cooled?
Is the 24000 running all time to keep room at right temp?
