Hi everyone, i've just moved into a new house, it's kinda old, the problem that i have is that the room i want to grow in has no power outlets, nearest one is about ten feet away in the next room, this outlet is on a 20 amp breaker, my question is, will it be safe to run two 600 hps, 6in extractor, and a couple of fans through an extension cable, any help appreciated, cheers,, goodluck.
