thanks for the info-i wont waste my time with an all fluro grow and already solved my height problem. If not home depot whered can i get the ballasts to run a hps at? I guess a regular electric store would sell em, but what exactly would i be asking for. Also (being the cheap ass that i am) would a 150 watt hps supplemented with some cfls be enough to sustain 2 small to medium size plants through flowering?

thanks for your help
