Topping is a technique used in the cultivation of marijuana plants to encourage them to grow more branches, which can result in a more even canopy and potentially increase the overall yield of the plant. Topping involves cutting off the top growth tip (called the apical meristem) of the plant, which causes the plant to divert energy from vertical growth toward the creation of new branches. This can be done when the plant is in the vegetative stage, typically when it is about 3-4 weeks old.
Topping can be beneficial for a number of reasons. It can help to create a more even canopy of branches, which can lead to more even light distribution and better overall growth. It can also encourage the plant to produce more flowers, or buds, which is what is typically harvested and consumed. Topping can be done multiple times on the same plant, but it’s important to be careful not to stress the plant too much, as this can lead to reduced yields or other problems. It’s also important to be aware that topping can alter the natural growth patterns of the plant, and may not be suitable for all strains or growing conditions.
Other methods include Scrogging and the Sea of Green, which are low-stress techniques that don’t require cutting
The Screen of Green involves using a screen to guide the plant to grow vertically instead of horizontally, increasing budding sites and light coverage without cutting
