Those tv programs you see where they show you a thermal image taken of a house with a grow in it always have a narrator saying something like "similar to this" or "coroborative evidence", in other words its all propaganja (lies, misdirections and half truths spoke about marijuana).
I dont know about the US, but here in Scotland, 7/10 busts are pure chance, a fire or something so someone calls the cops and they stumble upon a grow and the neighbours ALWAYS say "I had no idea until I saw the cops bringing a forest out of the house"
2/10 is people being grassed up.
1/10 is good police work.
Figures from the Scottish Crime and Drug Enforcement Agency show police have seized £41million worth of cannabis plants since 2006 and arrested 319 people.......... So in 5 years, there has been an average of 1.2 arrests per WEEK. The programs I have seen would have you believe you WILL get cought, the FACTS state something very different. I personally know around 15 people who grow and only 2 of those have ever been cought/prosecuted.
I know I am quoting Scotland but do you think it is that different in the rest of the Western world? The tv companies are the mouthpieces of governments in creating social order. The way programs make you think one thing when something completely different is the truth. Ask yourself this, how much of what you see in the media is the FULL UNSENSORED TRUTH? >1%?
Anyway, rant over, Dont worry unduly Hero, think things through logically, take correct precautions such as carbon filters and you should be ok. I run 2x 600W lights and because they are in cool tubes, the heat does not build up around the bulb so yes, there will be a heat signature but I doubt it would attract attention. The noise of the air pumps and smell on harvest days such as today would!!!!! This is my paranoid day, 20+ oz of fresh green smelly stuff hanging up.
Take a toke, smile and chill. W
