the main problem isn't the cops. it is the damn theives. if anyone knows you grow, they will eventually try to figure out where it is. they are either too lazy or too paranoid to do it themselves. that's why i always spread them out in tiny patches all over the place. makes it also harder for the cops to spot them from the air. i only visit them about once a month to check them. a miracle thing now is water crystals, a few in the bottom of the hole helps out in drought times. i have one more spot to check, and if it is gone, i will know who did it. then it is payback time.
