First, I would use all the bulbs, making sure I was heavy in the warm end of the spectrum. I think two plants in scrog will be enough, and given the dimensions you stated scrog is your best bet to maximize light to the buds.

Make sure your containers allow for good root growth, two medium size bubbler buckets would do it.
MajMike Reviewed by MajMike on . A lil help on an upcoming cfl grow.... I have a 2foot by 2foot by 3foot (covered in mylar), I'm using cfls all the right lumens for every thing as well as color temperature (for veg and flowering). I can use a total of 8 bulbs for each stage of the process (4 are in the middle of the cab, and the other 4 are in each corner, all are adjustable in height). How many should I use all 8 or just 4? Also how many plants could I get in there for maximum yield? I was thinking SGROG but not sure yet. Any tips and trick greatly appreciated. Rating: 5
