Metal Halide is the best for veg. In my opinion wattage depends on size of grow room. (More the Better) I use a 400 watt MH on a 6 foot light rail and 2, 8 foot H.O. florescent fixtures. 2, 110 watt bulbs each for a 5 foot by 8 foot area. I can grow 30 plants in that size room. Hope that helpsWhat lighting would you"s use for veg??
You can buy a Metal Halide conversion Bulb for your HPS set up. Much better in my opinion. MH lights will keep node spacing close and plants love those watts. you should have at least 400 watts of flo's if you go that way.thanks for help dudes!! i have a dr60 grow tent, so think i will buy some 3foot flour 100watt, how many of them would i need, will one colour do for the ladies??? i have a 400watt,hps, but im not going to use this until flower. sound ok??
