Okay so I have a little guy in a cup right now and bless his heart he's stretching so I think I need a better light source (currently using two 40w). The eventual location would be a closet about 7 feet tall and 3 feet wide, roughly 1.5ft deep so I'm thinking I want tubes? Does that sound right? I have access to Ace Hardware, Target, Walmart, KMart and I suppose Lowe's. I'm trying to figure all this out but I'm quite confused. The tube's are all so much more expensive so I don't see how that is worth it. So I guess my question is, what's the best light for two, maybe three plants? I think the guide said I wanted cool daylight and 6500k? That right? I'm going to continue searching but until then, thanks.
