Fact or Fiction

Ok I somewhat am a newbie at this outside growing. Grew indoors for a few years but moved here and now dont have the spare closet. But anyways my question is it true that some enforcement agencies have a detection system on the helicopters that can see your plants heat signature even if they are hidden or covered?

Yes....MJ gives off a heat signature and even if you have them concealed in a corn field, the pattern will be visable and different than the surrounding vegetation
