I dont mind using dirt,
Ill just put it in a larger pot.
Considering how I'm building everything,
I have around 150-200 dollars to spend,
I already bought 2 computer fans with AC adaptors,
and I already bought 3 100 Watt CFLs.
I have a carbon scrubber all ready built,
so my only thing holding me back is the seeds.

Also which plant should I be growing?
I was thinking northern lights, as they seem to be noob friendly,
but Ill only have 36 inches of height space to work with,
and 9 inches of depth.
The length of my box will be 50-60 inches though.

Would you guys recommend I go with Option B, and grow 2 (?) Northern Lights plants?
