In addition to the above, they also get quite suspicious light leaks from where people do not use proper ventilation and hook it to their furnace/fireplace exhaust vents.. and beams of light shine into the sky... which is why it's good to run lights at day, and night close to actual night if at all possible.. that said - FLIR.. the spawn of satan, although it doesn't stand alone.. if there's enough other evidence to suggest it, it may be allowed in some courts. Long story short, massive heat signatures showing up in 1 particular part of your house as read w/said FLIR.. either from the ground, the air with police heli, or both. Couple that with you being way too talkative, you lapsing on 1 bill or more, or anything that tends to draw attention to your operation is sending you on a crash course with the jail cell... unless you're in a state where it is both legal for medicinal and receational, and it's decriminalized. I do not have much information on that, but believe Colorado has such a setup. Control your odor as well! Any violent strain to the nostrils will waft miles on a light breeze day - you do not want such a thing leading to your place if they use a triangulation method with dogs. If they're to this point.. there's already been complaints, and I wish you tons of luck anyway. ONA DIY w/pre-filter, and ozone generator will go a long way to controlling that issue.
