Think of evidence of a lot of heat from a suspicious location, such as an unfinished attic area or an apparently vacant building. The amount of heat from one 400watt lamp would not be enough to look suspicious from the outside of a inhabited dwelling.

Shovelhandle Reviewed by Shovelhandle on . thermal imaging/ heat signatures The grow is on the main floor in a utility/laundry/mudroom. The air will be filtered and expelled through ducting and outside through the dryer vent. There is a door and a window nearby the totally enclosed growing closet/tent. The grow area is only 3 feet by 3 feet by 6.5 feet tall. 400watt lighting. Do I need to be real paranoid about heat signatures or thermal imaging in this scenario ? Rating: 5
