Possibly that one is, but mine isn't getting any added nutrients, she's an experiment from the rest of my setup, I'd say my main cola is twice that size, I'm only using cfls as well. I told myself if I could accomplish a grow with spending 0.00 and even harvest a half ounce, I will go at it again with the right equipment the right lights and nuts, and purchase reputable seeds. Every material I am using to grow; I already had. The Mylar, the cfls the pots and soil, all of it, so I mean naturally the yield will be low but, it's my first time and I've had no problems
