I might want to start a few plants but unsure if i'm setup properly. I got a 4 ft. flourescent with one regular bulb and a grow-lux plant bulb in it. Im wondering how many plants I can put under this, and if I might need another light for flowering. For soil I got miracle grow organic potting soil mixed 3 to 1 with worm castings. I also have 2 small electric heaters/ fans, and a digital temputure/humidity gauge. Its setup in a small walk in closet in my room, i got a nice lock on the door, plus there is like a small hole that goes from my closet to the space between my roof and somehow has a nice draft of fresh air coming through it.
