ok, this is the type of shit I know. I do not know law, or which states do what for growing. But I do know about how heat works, and how they read it. Like these people have said, they will have trouble telling a heater, or water heater and such from your plant area.. Depending on how large you grow area is.

If you have a small grow area. With minumal lights, I wouldn't even worry about it. I might even just use CFL's for the veggie part.

But if you have a large area, I would grow during colder months of the year, if you have a grow area of lets say 8'X8', then over this area, place 3"-8" foil faced Rigid Insulation, at 12'X12' and also place 3/4" rigid Insul. over the windows.

But I would never go to this extreme unless I knew they were watching me, and then I would not be growing anyway.

I use the 1/2" rigid Insul, to cover and dark out windows now. It works great, blacks out windows totally when cut correctly, and also helps control my temps in my room.

Got to go.. sorry. I will add if needed later. But chill.
Chabnoc Reviewed by Chabnoc on . infrared cameras on police aircraft I know someone who wants to grow for the first time, they want to grow in a closet in a state (in the U.S.A.) that has very harsh penalties for growing. You can get 1-6 years for 10 plants or less. Will aluminum foil block out the heat signature of 2 or 3 plants? My friend wants to line the ceiling of a closet with aluminum foil, because hes worried about police aircraft being able to see through the roof of his house with infrared cameras. He wants to grow for his own use to cut down on Rating: 5
