Enjoy. The link is permalinked to the post of interest.

400w is nothing. Estimate 1 kw per taxed legal bedroom of your home as your total allowance for growing juice. Remember to increase efficiency in other aspects of your lifestyle.
what she said!! I would remember to leave lights off when you aren't in rooms...close A/C vents to rooms not used as much...If you conserve, a 400w set up shouldn't raise your bill more than 10-15 bucks a month...and I would say 20sq ft grow space....IMHO
