hi i'm growing in a 3'x4' 5'10" high closet and i have some 500 w tungsten bulbs will these be ok to use, if not what type of bulb should i invest in?
Hiya, Tungsten bulbs are halogen or incadesent and wont work well for growing, I would suggest you get a 250 watt High pressure sodium for that size of closet, even a 400 watt would work if you can vent it well, but stay away from the 500 watt tungsten Good Luck Budguy
