Cannabis plants give off a unique infrared heat signature that any trained operator can recognize. a Thermometer in the soil wouldnt detect anything, its the heat that is being given off by the plant itself that is what they are detecting.

Police were also using this technology to detect house growing operations by looking at the external walls of houses, but the supreme court ruled these as illegal searches and police can no longer use it in that method.
Myth1184 Reviewed by Myth1184 on . is this true? Sup guys. Not sure if this should be in growing or legal lol but anyways... A friend of mine told me that if you grow outside helicopters use like heat sensors or somethin and they can see ur plants. He said the plants retain heat and are visible. Is this, in fact, true?
