that's a $40 150watt hps flood light (16,000 lumen). not sure if it would work, but prob just needs rewiring. You can buy 4' 54W high output T5 fluoro strips (5,000 lumen) for $25 each at Sun Blaze 54W 4FT T5 Fluorescent Strip Light - Plantlighting Hydroponics
If you already have a spot to grow everything, then most expenses should prob be for lighting.

Umm... space blankets are cheap mylar substitutes you could wrap that entire space in for less than $5.

I'm new, so I don't know much. Hope this helps. But you'd prob do best if you read read read threads.

good luck
