Which one of these would be better for a 2.5ft x 4.5ft closet? Closet is also about 8 ft tall. Just concerned about heat, but also want to max my lighting for the plants.
Here are the two diff ones I was considering:
600w - http://www.htgsupply.com/Product-Digital-Greenhouse- 600w-HPS-Grow-Light.asp
400w - http://www.htgsupply.com/Product-Digital-Greenhouse- 400w-Grow-Light.asp
Also, I assume I can use MH bulbs with the HPS ballast (just not the other way around unless it's a conversion bulb)... can anyone verify this??
