The power company aint gonna narc you out for using too much power. That's like telling the cops that so & so is buying way too much of your product. Not happenin'. Now your USAGE patterns are a dead giveaway, but as was said a couple of posts up, pay your bill and pay it on time!!! Keep it out of human hands.
Your greatest security threat is your own ego. Not you personally, but everyone who grows. I have no idea why I can bring home a fern, or some other decorative plant, and it's just a plant that MIGHT get watered. But throw a Cannabis plant in the mix and we tend to it like it's a preemie newborn. And the first thing we are DRIVEN to do is to show off what we have. It's an almost hormonal need to brag, and show off our growing prowess. Thank god for these forums where we can get our egos stroked with relative anonymity.
FLIR is another tool the police use that is a deterrent by the fact that we know they have it. We as They know that those who do not understand FLIR will be too cautious to try anything for fear of the cops using FLIR. They perpetuate the myth that they can "see" into your room, or have powers far exceeding the reality.
As of this date, they MUST HAVE a warrant to use FLIR on your residence (IF they're gonna use any of the evidence collected in court). FLIR is expensive, often times several jurisdictions will share a unit. The helicopter time is expensive, especially these days of $3 per gal gas. (AvGas is infinitely more expensive than regular gas), and if they are gonna use FLIR to prosecute you, the data from the FLIR must be interpreted by an expert in FLIR, and that expert MUST appear to testify in court. Understand that they CAN use FLIR without a warrant at any time. They just cannot tell the courts they did it, and no evidence collected can be used in court.
Keep your mouth shut and you should be just fine.
Now, all that being said, WTF are you thinking with 30K? If this were a legal grow as you stated earilier we wouldn't be having this thread. Legal grows do not have LEO security related issues to MY knowledge. Just rippers & pests. You gonna do a grow that big you may as well be outside.
Getting bigger is not necessarily a better thing. You can have quality or quantity, but you can't have both. You can find an acceptable balance between quality and yield, but the bigger the grow, the more quality will suffer. It seems that it would be neigh on impossible for someone without an entire crew to maintain a 1000 plant grow and still maintain the attention to each plant required to max pout quality AND yield.
I find that there is that segment of society who want the absolute finest smoke available, they want to KNOW what the smoke was grown with (Organically). For this clientele, cognac is OK, but it's VSOQ or nothing. These people will PAY for the quality. I'd much rather cater to that clientele. At least they have the connections to actually HELP you should the unthinkable happen.
God am I stoned!!! Sorry for rambling. Hope this helps.
