ok, morph, now i see what you mean.
but you need to see that the heat is something you need to deal with - if you can succesfully dissipate the heat, the extra light is magic to your plants! it's the light brightness that's really the key...more light = more energy = bigger budz. and hid's make the most light.
on a more philosophical note, it's interesting to note how steadfast and loyal growers are to their lights! i remember...way back when...we used mercury vapor lamps...they were the BEST...everybody knew it...and EVERYBODY who knew ANYTHING used them...then the other hid's came around...hps...mh...and today, i've heard some say you CAN'T grow under mv's...
