Voted yes but I have to keep the room cold.. 73 at night 77 in the day when it's 100 degrees here in Dallas. It run my electric bill up close to $400 and I live in a 1 bedroom condo. Also I have to reduce my lighting schedule to 5-6 hours. I have 2 halides in a 6 foot tank.. If I go 3 lights it will need a chiller for sure. Next year I may look in to a chiller to save $$$.
