Very small grow box plan

I will be starting my first grow soon and would like some feedback.

I need this box to be very small, stealthy, and cheap.
The box I am thinking of is a 1x1x3.5' box from Lowes.

I plan on starting 3 plants from bagseed in 5x5x6.5in containers with 2 26w daylight CFL. (3400 lumens)
Then pick one female to flower using a 2 gallon pot and 1 26w daylight CFL and 1 42w warm light CFL. (4500 lumens)

I will be using a computer fan to vent out the top and another fan inside for general air flow.

Do you guys think this is enough space, light / reasonable to pull off? How many grams do you think I could expect to yield from this? Thanks for any input.

You could do it but I would add more light. If your only growing one plant then the closet is big enough but I wouldn't think more than one plant could fit in that small space unless its a Lowryder strain. You can make a descent box out of dark rubbermaid containers and just stack one upside down on the other and keep it in place with a pin system of some sort. RM has a wide range of sizes and there only about 5 bucks for a med. size. Check on line for the elusive directions on how to do it. It took me a while to find the plans for one but they are there. Ill keep my eyes peeled. Good luck.
