Screen of Green is a low stress training technique that will increase your plants harvestable yield. This plant training method incorporates the deliberate bending and tucking of vegetation laterally and flatly to create a level uniform and flat canopy. It accomplishes larger than normal yields by enhancing the penetration and intensity of the light received by the plant. It also provides support that channels energy to the fruits and flowers rather than supportive tissue, displaces growth hormones to all flowering parts of the plant rather than a single large flower and lastly opens the plant to enhanced air circulation. Combined these plant benefits create a synergy that can double, triple or even quadruple your plants yield over naturally grown untrained plants.

First, the intensity and penetration of light energy, lumens, decrease as the plants distance from the light is increased. Scrogging flattens the plants vegetation much like a solar panel and that vegetation will receive (absorb) a more intensive light energy for plant energy conversion. Simply put, the further the light is from your plant the less energy per square foot you plant receives the closer they are the more energy the plant can use. The spreading and support of the plant also increases yield.

Garden netting allows the plant to focus its energy on its’ fruits and flowers rather than supportive tissue. As flowers develop, becoming larger and heavier, an unsupported plant will respond by thickening the side-shoots and branches that support them. This is energy taken from flower development, reducing your harvest. The addition of trellising to the plant helps relieve these stresses and focuses more of the plant’s energy on fruit and flower development. Displacement of growth hormones also results from ScrOG gardening techniques, resulting in numerous harvestable flowers.

Some flowering plants have what’s called “apical growth.” The flower growth is concentrated at the tip of the main stem, meristem, and has the greatest concentration of the growth hormone called auxins. The underlying lateral shoots have very low concentrations of growth hormone and result in small, fluffy immature flowers. When the top is pinched, pruned or otherwise removed, the plants’ response is to distribute growth hormone to all the other bud sites to stimulate flower development. What results is a shorter bushier plant that produces larger total yields than is possible by a single dominant flower. The ScrOG technique also provides for better air circulation and thus greater CO2 uptake.

When the flowering plant is flattened much like a table, held down by the horizontal netting, CO2 enriched air flows unobstructed over and under the plants vegetation. The better the air and its circulation the more uptake and growth the plant will have. This is easy to understand if you think about standing next to a table with a fan on the opposite side. The air will go under and over the table with the air reaching you much like a properly Scrogged plant. Vegetation that remains upright will block the air on the away-side of the fan circulating the air. You’ll know that your plant is getting proper air ventilation if the leaves are “fluttering.” Leaves that air moving in the presence of a fan air exposed to CO2 enriched air converting more energy through photosynthesis. A properly Scrogged plant will all but eliminate the potential for powdery mildew that is caused by stagnant cool moist air that doesn’t move.

The yield benefits of Screen of Green (ScrOG) growing are immense. Maximized light (electricity) efficiency, larger harvests and dense resinous uniform flower development. Regulation and law often limit the number of lawful plants that can be grown and ScrOG provides the means to obtain the same harvestable weight of one plant that would normally require 3 naturally grown plants.
