What a hell of a difference! Just lovin' me some T5's! Now imagine, get a bunch of bottle lamp kits @ walmarts, around $3.00 ea (the cord comes out the side on the bottle lamp kits, so no holes for wire need be drilled). You can use bottles, vases, but I use inverted clay pots. Heavy enough to be tip proof. Now, under the T5's, alternate plant, cfl, plant, cfl etc. Get the picture? Try it this way & I bet you throw that hps out the window! Or you could alternate cfl/plant under the hps the same way, but I'm liking the T5's too much!
