Ok, so this is my first grow

I just finished building a grow box last weekend which is 3ft wide x 2ft deep x 3ft high. I sealed everything with caulk,primed,then painted it then put weather stripping on the door so its air tight. I'll be growing bagseed using only cfls. I have 4 plants about a week old, and I started germinating 30 more seeds, so far 8 germinated so I put them in cups and im waiting for them to sprout. I'm only going to keep 6 plants out of the 34 so after a few weeks im just going to pick the 6 best looking ones. Anyway heres some pics.

Heres my box so far. 3ftx2ftx3ft high

This is my exhaust fan. It's a 120mm pc fan rated at 130cfm.

Passive intake holes. 90 degree pvc elbows with the insides painted black.

Heres the box with the door on and locked.

And these are the barrel bolts and locks.
