Your ego is your own worst enemy. ALMOST without exception, you are going to tell the wrong person, or the wrong person is gonna be privy to enough information to figure you out, and they will either narc you out, or rip you.
And Girlfriends. Ever hear that hell hath no fury like a woman scorned? What are you going to do when you break up? The chances are better than average she'll turn you in just to get even.
If you set up your room right, FLIR is a non-issue. The cops rely more on the fear of FLIR as a deterrent, rather than the use of it, as most people don't really understand the technology.
The power company isn't going to turn you in as long as you pay the bill on time, and don't steal power. If the cops start looking at your power bill, they are just adding evidence at that point, you are already on the radar.
Bottom line, tell NOBODY what you are doing. Don't let anyone close enough to even figure it out for themselves. The moment you tell anyone or they figure it out, the clock starts ticking.
There are always exceptions to this, but for the most part that's how almost everyone gets caught. The need to be the "weed man", or the need to be known as "the guy/gal who has the absolute best" weed around. If you don't have a huge ego, you're probably safe. You won't be compelled to tell anyone else.
Yup the ego will get ya.
Got a buddy here in Michigan. Got his card, started growing. In Michigan we are allowed 12 plants for a personal med grow, 2.5oz dried..plenty.
So after his first grow of 6 flowered, (his other 6 in veg) he yields close to a pound. All of a sudden he thinks he's a ganja god. Decides he should become a care giver, and get a couple patients. After all, he says, with 6 plants, and a pound yield every couple months, I can supply them too.
What's he do? Well, he rationalizes, since I'm allowed 12 plants for each of my patients as well, I may as well use the plant count. Increases his grow room size..starts flowering 18 at a time..harvesting 3 lbs every couple months. Far more than he and his 2 patients need.
Ganja god that he has become, (in his mind) he has to find someone to buy all his "overages"...well, needless to say, he gets caught with a couple pounds. He's only allowed 7.5 oz for himself an his patients.
He tries the "it's still curing so it don't count", the "I can't control how much a plant yields" and all the other self serving defenses...and of course loses.
Had he simply picked up the 2 patients...not grown more plants than his original 12 (plenty for all 3 people) he could have had free meds, a nice little profit, and been fine...but nooooo he had to be a ganja god...Ego..a definite killer.
