Hah, I left out a few details in my post but if he doesn't know enough about electricity or have an electrician to help him to do it safely he's fucked anyways.The explosive reaction when you tap into that wire coming direct from the transformer is going to leave a mark and those rubber gloves and boots will be melted on you like your new skin will be.
you cant grow that many plants without a generator. that much power get you caught by the weekend. i believe 1000watts per bedroom in a house is as high as you wanna go.
I like how you think... great advice!!!Let me point out to everyone that electric companies do send people out on a regular basis to look for what they call power leaks. This can be damage to power lines but it also is how they find most of the people that steal power.
I had a friend that was stealing enough to power 29 400w HID's and they nailed him five months after he started.
My suggestion to the OP is if he really wants to go through with that big a grow op, he needs to find some old rundown building out in the country to rent under a false id and create a business that restores something and keep the doors locked and odor down. Pay the big electric bills and hire a few illegals to stay there all the time and pray your not there if the place gets raided. If you observed all the security precautions you could and don't run out of luck. You probably get away with it for a year.
