i have been thinking of trying my hand in the whole indoor growing thing, but it would have to be small scale. So i was at my local home improvement center and they had some 70w hps and 150w hps and i was thinking of using the 70w. My question is will this be enough for one maybe two plants? also what about those quartz halogen lamps, the ones workers use, are those useable? they are like 500w...anyway thanks in advance.
