so i just started my seedlings under cfls. they are big bang by greenhouse. i have a 400w hps with a metal halide conversion bulb. i dont want to fry the lil babies so im waiting till they get a little stronger until i turn on the 400 watter. this is my first grow with a hps and i am wondering if a fan blowing on the light and one blowing on the ballast will be enough to keep the heat to a point where the plants can survive. Also how high above the tops should the light be. any advice would be appreciated
