With that much reflection in the box, 600W would give you some good buds and keep electric and heat down. I have 8 plants under a 400W right now. And if you want 1000W, you'd be better off with one light.
Pass That Shit Reviewed by Pass That Shit on . first grow this is my veg room runnin a 400 halide. the dimensions are 6ft high about 3.5 ft wide and about 5 ft deep growin some bagseed right now but a buddy of mine has got some humbolt clones he is gonna give me. my question is do you think 400 is enough to veg 10 plants and what would be my best choice for a flowering light for the ten plants maybe 15?
