New to all this and want to get it right first time. I have White Widow seeds in the post, and a cupboard space(1x2.5m) set up ready to go-reflective sheeting and twin tube flourecent lights on all four walls. And want to set another cupboard for the second stage-2x250 or 400 HPS with reflective sheeting and a home made(to fit) hydroponic system. Is this a waste of time? Should i just make two combi growrooms instead? Any advice would be greatly appreciated. Cheers.
