xcrispi Reviewed by xcrispi 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
