How Many Watts?

For 6 plants should i use 1 or 2 600w ballasts w/ phillips son t which is 90000 lumens each or one 1000w with a philips son t with 145000 lumens . I also cant really cut any holes for venting, would like four fans work?

Any of these setups would work. a 600 should be fine for 6 plants but more watts the better. The general rule is 50-100w per square foot. Two 600's or a 1000 is going to generate alot of heat so make sure you test it first. Mabe try some of these configurations if you have the stuff already and see how much heat is produced.
