Yeah, my electric bill is about 400 per month... If I had more room though, I wouldn't grow this way because I would exceed my max plant count.. I would instead grow around 75 Large plants under SCROG method.. I would veg them for a long time, may stagger their harvests to keep it continous. If I didn't have legal limits to worry about then I would grow SOG with a high plant density.. The Chronic is a great strain for this method.. I wish they didn't have the plant limits....
