lol like everybody else is saying, a single plant is nothing, the pigs up high in the sky in the big metal bird wont even notice anything different in the vegetation even with ten plants stuck together. Ive tended to plots with over a hundred fully budded plants all stuck in one plot, they were so big they were practically waving at the pigs to come get them lol. There is fly overs around here quite a bit looking for pot, but I never hear much of them actually being succesfull. Just think of the buddy flying the copter, they spend an entire day out buzzing above trees looking at the same crap for hours, green trees, green grass, green shrubs, everything green, many variations of green also, To be able to distingush marijuana plants among hundreds of millions of other green growing plants is a very extremly difficult task. Just make everything look natural, less bare dirt exposed the better, dont have heavy trails which you could see from the air. Yea, one plant buddy I woodnt even give a single worry about helicopters finding it. I think helicopters should be the last thing on your mind, Id be more worried about animals and people, Ive never lost plants to police, but ive lost thousands to animals and human over the years. You better make sure that one plant gets lots of love, and grows massive.
