Fimming, from the acronym FIM (“fuck, I missed!”) is a term used to refer to a specific trimming or pruning method used on marijuana plants during their growth stage. Essentially, fimming is a way to train the marijuana plant to grow more of the valuable compounds.
Fimming is very similar to topping a plant. The method encourages the weed plant to grow shorter and bushier. It also pushes the plant to create two heads instead of a singular head.
Fimming creates far more lateral branching on the plant. Growers perform fimming by pinching off the plant’s new growth or by using a sharp knife or trimmers to prune away the new growth. Great care must be taken to make sure that the pruners, knife, or the grower’s fingertips are sterile so that no infections are inadvertently transferred to the plant during the fimming process.« Back to Glossary Index
