Hey guys and gals, need your help - I'm looking for a link to a simple grow box, that's as small as possible - I know that's a common request, but I figure I can go about 4 feet high and 2 by 2 - enough for three plants, I'm hoping - how much light would I need, etc? I want to go as cheap as possibly, so if anybody has any good links, let me know. Thank you!

heres a link for some good cfl lights,
Light bulbs, Rope Lights, Halogen and Fluorescent bulb - 1000-Bulbs - The Light Bulb Superstore

you can use the 27 watt 6500K and the 27 watt 2700K.

the 6500k is used for veg. and the 2700k is used for flowering.

you can get any computer case fan. to get it to work with an outlet, get a dc adapter 12v. or just get an inline duct fan 4" of 6" itll be good enough.

for odors, do a search on google for "DIY carbon filter" or "DIY carbon scrubber". pretty much, the exhaust fan hooked up to the carbon filter/scrubber.
heres two, DIY Small Scrubber - The Garden's Cure and Ryoko Builds a DIY Activated Carbon Filter - 30 Minutes, $30 Dollars - The Garden's Cure

you can use a power strip or a power cord y splitter.

for the inside of the box, either paint it white, or get mylar film, and use the white side of it.
Reflective Mylar

ALL of these supplies can be picked up at your local hardware store. Hope this helps.
