Basements rock!! IMHO
As skink stated, build an enviroment, you can use really cheap materials, and get stunning results.
6 years ago, I had $500.00 bucks to use, for everything...my very first cut was a measley 67 grams dried packed away bud.
Now that same box, gives me 4-5 times a year 3-5 ounces...with 320 watts of light and wee blower!! About $25.00 a month to run.
