I don't know what keywords to use for our search function and when I searched Infrared Detection it came up NULL .. I'm just curious if some of the ole hippies on here knew or know how to keep overhead detection attempts from seeing the heat off of your plants while flying overhead ????? I mean I've seen other movies and shit and I know there is More Expensive junk to buy to surveillance proof the grow yard ? ya think ? anyone with pertinent information on this would be gratefully appreciated . Thanks .
