I have a 1000 watt metal halide set up. After my seeds sprout they grow very slowly for the first few days and gradually turn yellow and die. this has happened three times now. Its in a closet space that is not easy to keep cool. some people have said I might need some kind of light filter. some people have said my lights might be too close. I really don't know what I am doing wrong. the lady I bought the light kit from said the bulb was a "metal halide bulb, but that it has the full spectrum of light from metal halide and high presure sodium combine, so I can use it from start to finish". I'm learning as I go, was it a mistake to get that bulb. Should I have just got the regular metal halide. Is my growing area to hot. I really need some Ideas here, I spent alot of money on these lights.
