Growing Congo Haze in Cabinet

Alright, This is the first time I post on this site. I been reading everybody forum but regardless how much I read, I realize that I need to do some growing in order to learn. Anyway, I just got two clones of Congo Haze and right now, they look like a real beauty. They are both in a "party" cup with does have holes in the bottom for drain. Will be trasnfering them in a larger plant pot. Even though they are small (They're about few inches with leaves) I have them under two lights. They're Daylight energy saver which give out 1500 Lumens each. So that mean I have total of 3000 Lumens pushing out. On yeah, the total space of cabinet I'm using is 27"(w)x12"(D)x50"(H). Inside my grow box, I have a "Greenhouse" setup. Soon, I will be building DIY carbon air filter. I already got a small fan for it. Now, from here on.... I need some input and some idea in order to make it a successful. I will be posting some pictures soon.... just as soon as I get a new battery. Lol
