Topping in Cannabis slang refers to removing the Terminal bud or "Crown bud" on a growing cannabis plant, this will sometimes cause the plant to form a branch node in that area, split, and form multiple Terminal buds, increasing yeild. This is often confused with the act of removing the top of a plant to prevent seeding, which is not often done with Cannabis (besides harvest of course). Cannabis plant will not seed if they have not been "feritilized" with male pollen.
