Fimming is a technique of cutting off the top of a shoot to stimulate the growth of four new shoots instead of two. This technique can be done on any branch, but some cannabis growers prefer to do it on the main stem only. The advantages and disadvantages brought to the side branches depend on several factors, such as the variety, the environment, and the goal of the grower. Filming side branches can help create a more uniform canopy and increase bud count, but it can also reduce yield and bud quality on those branches. Side branches may also require more maintenance and training to avoid overcrowding and shading. Therefore, this is not a one-size-fits-all solution, but rather a personal choice and a matter of trial and error.
