400w hps

How close should it be to my plants. I have it about a foot and a half away cause any closer seems to hot.

that's about right, you could back it up a lil if you wanted.....

rule of thumb, put the underside of your arm at canopy level. if it's too hot for you, it's too hot for the babies.
