Reccomend a type of weed to grow?

I only have a small area to grow in.

The wooden box is about 3feet(1m) tall by 2feet(~.75m) wide and about 2feet deep. I can move this into my closet for more room once the plants get bigger, but I want the plants that I grow to stay relatively small. I've read that White Widow stays small, but can anyone reccomend any other types that stay small, yet produce a decent amount of bud?

We used to have plants growing on the other side of the neighborhood in the woods. Some little kid found the plants, called the cops, and now the cops are on a lookout (I live in the US) for people growing weed. I would like to grow indoors for safety reasons, but the helicopters that fly over are always checking for extra heat coming from an enclosed area.

I have a fluorescent light setup in the cupboard where I plan to grow already.

1) Reccommendation for a strand of small, yet potent, seeds.
2) Lights that do the job, but give off little heat.
3) I don't have a credit card, so any website that would sell seeds via money order or cash.

EDIT: How necessary are fertilizers to indoor plants? Do they have to be fertilized? I would assume not, but I would like somebody else's expertise.

I've got some seeds 'germinating' in some plastic cups with soil. The cups are in a shoebox lined with foil. There is a Fluorescent light on top of the shoebox, delivering heat to the cups that have non-sprouted seeds in them.
Does all of that sound ok?
