is it possible to do a SOG with only 4 plants?** The ScrOG Concept **
Growing with fluoros gives one a good understanding of light to plant distance because it's so critical. Even so, HID users still appreciate the impact of having as much growth as possible, as close as possible to the light. It's how to make best use of what you have.
In the process of achieving the above, the shape of the growing canopy would match a line in space where light intensity would be equal as it eminates from the light source. With fluoros, it's a perfectly flat plane. With a stationary HID it's a concave shape, the degree of which depends on the area covered. With an HID on a light mover, it's a perfectly flat plane.
Training is a method of growth control that allows one to shape their canopy. Tying, bending, crimping, topping, are all training methods. Training branches to grow where one wants in order to get the desired shape takes time. At best, even though branches are where one wants them, when the canopy is in full flower there are void spaces between the buds where other buds could be growing, but aren't.
The Sea of Green method, where many plants are used in an effort to eliminate the void spaces between buds, was named from the vision of seeing the procsess in use. The canopy looks like a "Sea of Green".
Either way, extra effort is required to maximize the use of canopy space. The plant's shape and the shape we want from a canopy under artificial lights are simply not the same. IOW Mother Nature will not cooperateThe extra effort comes in the form of using more plants (SOG), or training fewer plants.
After finding from experience that I didn't like maintaining the numbers of plants, mothers, and clones needed for SOG I opted for using fewer plants. I had to train but still wanted that Sea of Green horizontal profile and no void spaces in my canopy.
Enter the Screen
When a length of poultry netting is stretched over the grow area, it eliminates the need for conventional training. Tying, bending, and crimping are replaced by using the netting as anchors to keep shoots in position. It can also be perfectly shaped to make best use of the light. The netting is known as the screen, hence the name Screen Of Green or ScrOG for short.
Plants are topped to promote branching, as the plants grow into the screen and their shoot tips start to grow through the holes in the screen, they are pulled back under the screen and guided to the next hole to continue their horizontal growth. All the time maintaining the profile of the screen to maximize light use. Growth is very robust. While now getting the same light intensity as the primary shoot tips, secondary growth seems to blossom, and from the secondary growth comes tertiary growth, etc.. All at the top of the canopy, and all receiving maximum light intensity. How many plants are used depends on how much time the grower wants to take to fill the screen to a point where it will be full with buds at harvest. This will largely depend on the growth traits of the variety he uses, but one can fill a canopy with only one plant if desired.
When flowered, only the slow growing buds are allowed to grow through the holes in the ScrOG. The resulting harvest profile is indeed a Sea Of Green but with much fewer plants and the increased yields gained from making use of the void spaces found in a conventionaly trained, non-SOG canopy.
), simply ramp up your mother plant's lighting and give it a little boost of nutrients so that it begins actively growing again. Okay, maybe two weeks, to allow for the rooting process, but you probably get the picture.
