Are you stupid, peoples electric goes high all the time they don't care as long as you pay them, they only get suspicious when you are running like 4kw on a regular house, if he wants to do an expensive underground grow op then he has the power costs covered lmao. You can rent excavator, im sure if he has enough for a shipping container doing the test for the excavator wont be much of a problem price whys, or you can allways hire a guy who does, and make some bullshit excuse. You do relize that when people are doing big grow ops they have the money to invest, or i should hope so if they are doing it.
