it is possible, an acctually likely you wont be caught....its not something i do, anything i grow is all natural i let my plants grow themselves how nature intended, but for someone that is indoors an have power issues it is an option, if it were me i would just take them outside an let them enjoy some of that free sunlight they so much love.

wow, just grow outside, its much easier, and cheaper, but mother nature may not be as nice to u.

3 42 watt cfls dont use much power. 12.6% of a kw/h. So depending on how long the lights stay on, and how much the power company charges for 1 kw/h will tell you the increase in the power bill. Say the lights are on for 18 hours a day, thats 2.268 kw/h's a day, and if the power company charges $0.20 a kw/h which is way more than I think it is...your bill will only go up $15 a month. I plan on using a 400 watt hps and 4 40 watt flourescent tubes for my room.

You could also try to lower your bill by putting more efficient lights in the rest of your house. Instead of a 100w incandescent bulb, you can use say a 15w compact flouresent. That would counter the increased power usage from your grow room
