I like the look of the plant under those cfl's.

BUT - 500 watts for one plant that size, seems like alot of power for one plant. A 400 HPS could easily produce 4 plants of this size.
Your total weight is yet to be determined, I doubt that 8.9 ounces is what you will get, more like maybe 2 at the most.

Not trying to be a nay sayer, I really like the thickness of the buds.
