A big thank you to the GC community for helping me with all my questions so far. Now what im wondering is how far can IR cameras penetrate into a house to see grow lights from copters and such? I only plan on growing a few plants. four at the most, so one light should do me. Do i need to be concerned about putting the light upstairs? I have an attic, well insulated, about 12 feet tall. If i grow upstairs the light would be about 13 feet below the tip of the roof. Should i put the lights downstairs, or in the crawl? Not as tall down there, bout 3 feet or so, but if it avoids detection that might be best. Id like to put them upstairs, so i can keep a door locked on them. Any ideas?
