  2. No offense, but please improve your grammar so we can better understand you :p Also, your thread title says "4000 watt...." That would be a monster of a light!

    Four plants (I assume that's what you meant) under a 400w is just fine, probably perfect. You'll have a seperate ballast with it so you'll have to learn how to manage that. It'll produce a lot of heat, too, so you need some pretty good ventilation. If you have the space/money to accomodate for it, then go for it.

    Do a search here for 'sunmaster' or whatever the brand name is. I'm sure you'll find something. Most people here seem to like the 400wHPS, without any ill effects that i've heard of. It's a good start for a small op.
