FLIR Detection

I live in a highly populated area, and who knows whats in the sky at any given moment... my question to you all is, do you believe that mylar tents (most which are light proof) really protect you from FLIR devices? I'm a little paranoid now... but the show must go on. Also, can FLIR detect lighting in the day time, and if so, is more difficult or all the same? Just curious, thought this could be a good discussion.

unless your running a few thousands watts, i wouldnt worry about it mate.

FLIR detects surface area temps. So a room in a room is the best way to avoid detection. In other words just don't have an open room grow. Tent in a room or room in a room is fine.
