check the grow link in my sig. Yeah, its hydro, so it doesnt really apply to your parameters, but I KNOW you will need to increase the amount of lighting in there if you plan on getting any bud at all.
we're moving into the warmer months, I assume you run A/C in your living area. what I would suggest is to cut a vent hole in the bottom of the rubbermaid and sit it on top of your AC vent, this will help keep the temp downs so you can Increase the number of lights to at least 4 23 watt cfls. I would use the blue CFLs for at least the first 3 weeks, that will help tame some of the killer stretch you are about to experience with 12/12 from seed + limited light. First grow + limitations I'd say .25 grams per actual watt (.25 x 46 watts). If you get more light in there AND take care of the heat they produce, you'll see that number rise drastically.
