alot of people think MH is bad for flower but the truth is the opposite, MH bulbs will give you way better potent buds but you will lose up to 20% of your final wieght while hps gives you quanity but not that quality of MH, i still believe hps is a better flower bulb but MH works awesome too

i myself use just hps w/ no probs.or adverse affects .
i use EYE hortilux brand bulbs so there is increased blue/green spectrum during the veg. stage .

Thanks alot everyone for the info, it really helps. Now its just up to me on what to do.

I would def. reccomend using both bulbs though I've read arguments that you can use the HPS the entire way through, and also heard arguments that you can use a MH the whole way through... it's pretty common practice to buy both and that's what I personally reccomend.
