Pre pair your areas in the winter time. Try to go into the deepest thickest brior patches. get good sun light as well as consealment. If you spread out 30 good plants over a 1-2 square mile area. and place then under low trees wear the sun still gets to them for most of the day .Like the south east facing hillside. Your succes rate will be high. Also open areas in the middle of the woods are good to as long as they are not to big and open Nail your buckets up on the trees on the edge so you get the sun but deer wont get them .Hang on tree stands for hunting work well for this method as well. I persnonally would stay away from corn feilds. If you make it harder, yeah it is more work. but you will have somthing to come back to in the fall. The key is spread them out and leave no trail.It can be a full time job to do a desint outdoor grow....
