Do's: Provide camouflage. Planting weed next to corn or hops works well. Plant in patches, or bend plants over and tie to the ground once they reach a noticeable height. Wrap plants growing in pots on the patio in coloured plastic. Pinch tips of leaves off to improve potency and resin production.

Other growers remove entire branches or plants. Pinching off tops diffuses floral hormones, sending them back to lower branches. The increased hormone concentration signals lower branches to grow taller. Snipping tips also initiates a new set of branches to grow below the cut, but does not increase harvest weight..

Some varieties of cannabis can grow to 4 metres in height; if this is a problem they may need to be pruned or trained. Pinch out the growing tip when the plant has produced 4 sets of true leaves; this will make the plant branch into two main stems. Pinching the growing tips again will further increase branching. Be careful not to overdo this process as the plants are stressed by pruning and their development may slow down unacceptably or they may even exhibit hermaphrodism. Upper branches can be bent horizontal (carefully!) and tied to canes with garden twine. This encourages budding at the leaf nodes and reduces the overall height of the plant.

It would be a good idea to buy a copy of CONNOISSEUR'S, if you are planning to attempt this, and read Mr. Drake's complete instructions.
Another still-experimental process to increase the resin it to pinch off the leaf tips as soon as they appear from the time the plant is in the seedling stage on through its entire life-span.
This produces a distorted, wrecked looking plant which would be very difficulty to recognize as marijuana. Of course, there is less substance to this plant, but such wrecked creatures have been known to produce so much resin that it crystallizes a strong hash all over the surface of the plant - might be wise to try it on a plant or two and see what happens.
