For your weed grow it needs to be in a completely dark box to sleep 12 hours so it will flower. Any light during those 12 hours of sleep and it will never flower and just keep growing like a houseplant. That includes if you are peeking in the box when it's asleep.
I would suggest you at least buy one of the $20 150w hps's and some used kitchen cabinet and start going to work setting up a decent liitle grow.
You could use one of those hps's just for your houseplant tent, with a reasonably decent looking hood so it looks all nice. 4" furnace ducting or even 6" makes a good looking and simple as hell reflector for that. You'd be looking at a $54 investment in two of those lights shipped and probably $5 for a cabinet at goodwill or a garage sale or whatever. One light and a cabinet for $35 or so and a couple fans one for exhaust on top, a passive intake in the bottom, and a fan just to blow air on the top of the plants and on the bulb.
That one guy is right, stop fucking around and get serious if you actually want to get some bud. (not to be a dick, just trying to make that clear)
