Dude is right. "partners in crime" are a bad Idea. you gotta worry about who is doing what, or saying what to whom. Too many people involved and someone is absolutely certain to "Brag", or "Show off" thier part of the grow.
And I'm here to tell you.............. I don't care HOW WELL you think know someone, facing time does wierd things to otherwise reliable people. I can guarantee you that if it comes down to either them or you, you are fucked!
Another factor I see that you heven't figured into your scenario is your "Contingency Package". Screwing around with that much weight, you are gonna need a bail bondsman and a good attorney on retainer, and a good stash of cash handy. You need to make absolutely certain you'll get out if the worst happens. That contingency plan will set you back about $10 G's, but the peace of mind is well worth it.
Why don't you take your money and do a smaller crop. With no one else involved you'll me making the same bank or more, with a whole lot more security and control over who knows what. From all I have seen and heard, almost EVERYTIME someone gets busted growing indoors, it's the result of someone running thier mouths. Forget FLIR, forget the electric company. from what I've seen, snitches are the way 80% of all grow ops are discovered. Greed or stupidity make up the other 20%.
