HPS and some use MH for last several weeks prior to harvest. Keep an eye out for plasma lighting and LED's they are evolving.

Hps is good for flower and t5's are good for seedlings,clones and small to med size mothers. For optimum proformance in the bloom room use 1 Hps and 1 mh bulb to get both blue and reds for a better full spectrum.

I am using standard t5s right now
Starting threads in the General Marijuana Growing section to ask this question shows that you have not done your homework and it demonstrates your lack of competence. If you began growing cannabis plants before knowing what light spectrum to flower in then you're a moron. Get off RIU and read an introduction to cannabis guide.

Hortilux Super Blue bulbs are what I want to use in my future grow room. They combine a 600 watt HPS and a 400 watt MH into one 1000 watt bulb giving you a well balanced light spectrum.
