heat signature

  1. does anyone know about the heat signature of the plants? any information would be great. like how the swine detect it with their ray guns or whatever. how much is detectable in an outdoor grow in the woods? would any city have it in the birds?

    oh yea, i dont live in canada so american info would be good.
