I was planning on just buying more of them and setting them up to a timer in a closet. Would I need different lights?

It's a small closet, but bigger than that desk you're growing yours in. My only problem now is venting. The closet is small on width but goes pretty high. Would I still need to drill a hole for venting? Or could I just have some small fans running on them? I rent this apartment so drilling holes for vents would not be cool.

As far as watering, I read a lot about the beginning stages of cultivation, so I know up to that, and how to/how much to water them is included. I had NO idea I was supposed to prune them so early, I never saw any time frame for that. But now I'll know for next time. I plan on growing some more ASAP.
