Tube Fluor Cab Grow: Need Help!

Well im doing a cabinet grow.

23" High(but there's a removable shelf 11 1/2 " )
42" Length
12" Wide

Right now im using the top shelf with the two 20 watt fluor tubes, i screwed the fixture in to the top of the cabinet, and i have them between 1- 2 inches of that light.

(i have them jacked up with stuff under them, removing as they grow until they are flat on the shelf. At which point I can lower the shelf to an appropriate level).

It's all white walled right now. i'm only looking to do 4-6 right now (more are sprouting, but since im using bad seed im gonna *weed* out the weakest most likely).

Each of those tubes are suppose to be 1075 lums so i was hoping 2150 would be enough with the mylar on the walls.

I would def work out something different for flower. Suggestions? I'm considering CFL's since that was the way i was going to go originally.

I plant to top/fim these guys. Even if i just end up with 2 good fimmed that's fine. I really don't want them any taller than a 1 'foot 6" inches since my space isn't that high. Is it possible to keep it that low?

I do have a 4 foot tall growbox that was used by someone else available too me, but i'd prefer to keep them where they are.
So if it comes down to that it's fine.

I'm going to work out a vent system soon, it's not that hot in there currently so i have a little time.

Let me know what you think.


Things soon to be aqquired:

Mylar
PH Kit
Fox Farm Soil/Nutes suggestions? (Reading FAQ: Agway 'manure and humus' product possibly instead of fox farms. Opinions?) $$$ is also a factor.
Temp/Humidity reader
CFL's for veg and flower. (Blue if tubes not enough and red Spect. for flower.)
6" pots
Fans ( Might use a power supply i have and pump it out of the cabinet. Fan suggestions?

I'm sure there is some crap im missing, still drinking my coffee so maybe i'll remember soon! :P

Thanks for any input
