400w hps with 400w mh (good or bad)

Running both is actually the best route. Both spectrum's benefits during both stages of growth.

even though one side would get more of one type of light than the other side would is ok?plants on both side would be the same?

the plants receiving more light from the mh may turn out slightly different from the plants receiving more hps light..
if thats a problem you could occasionally move the plants around

or tilt your lights so they both shine over the whole grow.. dual spectrum is good for plants but yea, rotate, tilt or something so they aren't getting too much of one kind all the time.

Im doing that with 2 mh and 1 hps in the middle and its goin great.......

Ye, I was thinking of adding a couple of 125WATT Blue CFLS to my grow.

CFL - HPS (400) - CFL

Have the two CFLs on each side real close, the 400MH doesn't quite full the space and the CFLS are pretty cheap, they would only have to produce an extra 1/2 Oz to pay for themselths. Can't decide wather to get RED ones or BLue ones.

how often should i rotate my plants if i use the hps and mh, as i read on here i see how people are writing about using floresent lights or such that are either blue or red.how does that affect the plants and should i do it

if you have the money for a bunch of cfls to add in there you can always go for it. also I would rotate almost every day just to keep it really even
