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
invision Reviewed by invision on . Metal Halide or Hps or both Ok I thought I was on the rite path and decided to go with a 400w HPS. Then I did some more reading and heard its better to start your young ones with a Metal Halide light during veg and then switch to the HPS for the flowering. Then I read this post and it only threw me off more pH Water - See More Buds. From what I got from it, HPS is the way to go all the way? So my question is, would it better to go with Metal Halide light for veg and then a HPS for flowering, or should I just use Rating: 5
