Growing in trees

It may sound funny, but for smaller (and sometimes even fairly large) outdoor grow operations, growing trees in trees can be a successful method for getting some decent head stash.
Humans have been growing plants in trees dot centuries, and for several good reasons.
The smartest reason is to prevent the bigger trees from stealing your plants’ valuable sunlight: Why not raise them up to the level of the forest canopy and get them better light instead?
The next reason is security. If you don’t want anyone to find your plants, what better way to hide them than to stash them high above the ground, where human don’t generally wander? Aside from human traffic, protection from ground- dwelling animals is also a huge plus, especially if your plants are still relatively young and small when they’re brought outdoors. Of course, there are some disadvantages to this technique as well, such as accessing your plants for routine mantenance. And the question of how exactly one houses plants in trees is a tricky one.

Today, this problem is easier to solve, as some companies now manufactured tree pots.
These ingenious devices simply place a plant container (with holes in the bottom) inside a reservoir bucket. Rainwater drains through the container and fills the reservoir below.
Popers run between the container and reservoir, acting as a wick system for roots to draw up the stored water as needed. These buckets generally come with camouflage bags that blend easily into the canopy.
Guerrilla growes sometimes affix several plant containers to a long board and then attach these boards high up in the treetops. Once strongly secured and stabilized, the buckets are filled with a light soil medium, and young adult plants can be transplantes into them for the warmer grow season.
