I recall reading an article on GC (might have been RUI) where a CAMP chopper pilot was a member, and pretty friendly. I'm paraphrasing a bit, but he said:
The only time I can't find plants is if they are under camo netting. I recall one time a ground crew radioed me to come back to a spot I had overflown maybe 6 times that day, where they had found a large grow. Hovering overhead I could not make out anything at all, even when I was told I was directly over the plants.
Use that how you will, gentlemen.
Also, FLIR detects the dark fresh earth under the plants that is typically well watered and maintained, making bright circles on the FLIR (as the dark earth absorbs more sun radiation.)
