hey folks. i was hoping to get some feedback on a situation I'd like to resolve...I'm growing tomatoes & peppers indoors over the winter and would like to add a mh light to the room. right now I've got a t5 in a large cabinet and a 1000w hps in the other...the t5 cabinet starts my plants and then I've been moving in to the other room. I'd like to add a metal halide lamp to the the room w/ the 1000w hps. here is my question (finally)....the MH that I add...does it need to be 1000w or will something a little lower be okay? thank you.
