a small professional pot growing setup would be the equivalent of introducing at least 10 electric heaters...there's no comparison to any thing anybody can do at home and still be considered a regular user of electricity... unless off course that person has a house like a rapstar, and has 20 homies living in that house, you know, like in mtv cribs...
over here, what happens is , the potmaffia rents a shed, set's up shop, bypassing the electrical meters
they know that the operation at some point will be discovered, but that's no biggie, it's a calculated risk... if they can get 2 or 3 harvests out by then, then that's fine.. they have other sites going up all the time
