Scrogging is the use of a screen that is placed approximately 20 cm or 8 inches above your cannabis plant which encourages the branches to fan out across, creating a horizontal canopy. As soon as your plants make contact with the screen, you can start to guide your plant through the openings in the screen.  When a tip grows a couple of inches above the screen, you’ll want to tuck the shoot under the screen and into the next open square. In this way, you can determine the direction that you want your branch to grow. Try not to have more than one shoot in each square so that each branch gets an optimum amount of light and space to enable it to produce bigger buds.  This process should begin slowly but be done through the entire vegetative phase of growth to end up with a filled screen before your plants enter the flowering stage.

The lower branches and any dead leaves on your plant that are below the canopy should be pruned to allow for the plant to focus energy on the branches above the canopy. This will help your plant to produce high quality buds.

Scrogging may stress a cannabis plant so giving it some direct light and watering your plant within 24 hours is a good idea to help it weather the stress of the procedure.

The benefits of Scrogging:

More light exposure:  Because your plants are fanning out in a horizontal manner rather than growing upwards, they are exposed to more light which in turn produces more buds and more yield.

Aeration: you will get more air flow through your plant which helps prevent mold and reduce the presence of pests.

Maximize your space: Scrogging your plant or plants can often produce a much higher yield than plants that have not been trained. When you are confined to a small space, maximizing your output is paramount!

Strains that are more suited to Scrogging:

Sativas, which are tall and lanky, are well suited to the scrogging process because you can easily weave the branches through the screen. When growing a single plant, you can use a larger pot to allow for good root development and a substantial canopy. Some strains mentioned are Green Gelato, Superiour OG Kush and Bruce Banner#3.


Scrogging may appear to be a lot of work, but the technique is quite simple, even for growers with limited experience.  The end result of scrogging, which allows plants to receive optimal amounts of light and space, is high yields and potent buds in an efficient use of space which, in our opinion, makes the process well worth the effort!
