you think big grow ops are cheap? you need to do what you need to do, if that means getting the license and paying a deposit on an excavator then so be it. as for electric you can say you have hobbies that use electric, i heard somone say pottery wheels use more than a kw on electric, combine that with the tv on an electric heater, and your computer checkinh facebook, along with you,re aquarium and reptile tank that is almost 4kw right there, not everyone who has a high electric bill is growing pot, i heard of people having more than 5kw on a regular house and having no problem except for heat.
