Ya probably but you left out the cheap part. A 400W in 4.5 sq ft would be nice though, and I wouldn't have to upgrade down the road.
If I were to go 400, I'd have three problems. First, pulling all that electricity though one outlet, 15A breaker. The only other thing on the circuit is a deep freezer. That would make me nervous, fans, pump, 400w hps, digital ballast, all on one plug. Is that really safe? Im not trying to catch my place on fire.
Second, would be the heat. Would a 6 inch duct fan hooked on to an air cooled hood would be enough. My temps are already a little on the high side, 74-77.
Third, what kind of digital ballast would I need for that daystar reflector? Again I wanna get top of line relector to maximize things. Daystar seems like a good buy and it fits in my room. Will any digital ballast work or is there is some sort of matching?
