One thing that is important with the outside crop and that is to be as sure as possible that there will not be any walkers or hikers that will come across the crop. This is important for two main reasons, the first is that they might report the crop to the authorities; the second reason is that they might watch the crop until it is ready to be harvested. This is one of the reasons that growers with outdoor crops do not tell their friends about their crops location also, this should be a closely held secret.
This marijuana crop that is hidden also means being careful not to leave a marked trail to the crops location. The denser with underbrush the walk to the location of the pot the better, this means that coming and going will not leave a marked trail and it also means that there is little chance of someone walking up on the crop. If the area does not have underbrush then it is important to cover your tracks when leaving the location, so that other walkers or hikers do not follow the trail thinking it is just any trail.
