The spectrum mj plants emit is different from natural foliage & the buds hold in heat longer than natural foliage making them visable in the early dusk hours , however FLIR & spectrums isnt what zero's cop's into a guerrilla grow , it's allways human error , some error's have been pointed out by other members while other error's have not , Mj plants are not naturally growing plants & do not share the same life cycle as most forest plants , come september all tree leaves are turning red & bushes are defoliating & wild grasses are dying off , the only thing thats a healthy green color is mj , your best defense is to stagger the plants with only like 1 plant every few acres of land . an acre is only 208 ft x 208 ft so from above the tree tops the foliage within a10 acre area is easily disected by the human eye , stagger the plants & use multiple plots .
Other shit that draws attention is freshly moved soil & planters mix , perlite glows like a mo fo , trash & debris too , beating a single path to the grow is a road map , cop's aren't stupid about where to look , they'll start a search where water is in easy reach & off road parking is available then work out from there in grids & what they are looking for is mj patches where they can grab alot of plants at 1 time , staggering the plants over a wide area makes them less attractive for cop's to go after because it's added work load .
If you plant 20 plants within a 30 acre area it's highly unlikely you'll get popped even if they are spotted , just use your head & dont get greedy , brag or have partners .
