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 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.
It’s possible to fimm a plant that already has two heads, thereby creating four or even five main (crown) buds.
Growers frequently prefer to use a curved blade to make a dished-out cut. Fimming should be used in conjunction with other growing techniques to successfully maximize the cannabis plant’s yield. Ultimately, fimming away the plant’s common singular bud will encourage it to produce two buds, which double the plant’s production.
Oddly enough, fimming is actually a term spawned from the acronym, FIM, which stands for ‘fuck I missed’. In other words, fimming was discovered by accident, when regular topping went wrong, but ended up being successful in the long run.
Fimming involves removing the marijuana plant’s new growth tip at the very end of the stem or branch where it meets the foliage. Growers cut away up to to 75 to 80 per cent of the tip. The remaining buds will be able to take up more light, which will ultimately increase their final weight.
For best results, fimming should not be done until your plant has three to five nodes (sets of leaves) in total. After that, once the plant grows more and more, it’s possible to fimm the same plant more than once.
Fimming is very similar to topping a plant. The method encourages the cannabis plant to grow shorter and bushier. It also pushes the plant to create two heads instead of a singular head.

When topping your marijuana plant, it’s best to top the plant when it is young, and has 4-6 nodes (sets of leaves) in total. Although you could do it a little earlier, you’re more likely to accidentally stunt your plant the younger it is. Additionally, the less actual plant matter you take off, the less likely the plant will get stressed. Think about it, if you’re taking off 10% of the plant it will have much less effect than if you took off 30% of the plant.
These thickened connections demonstrate that your cannabis plant is spreading energy more evenly across the whole plant.

FIMing will often not make symmetrical colas like topping. The resulting number of colas becomes less predictable.
Never FIM Cannabis in the Flowering Stage!
Note: The unfortunate acronym “FIM” stands for “F*ck I Missed,” and refers to growers accidentally pinching off top growth instead of fully topping the plant between nodes. FIMing has become known as a technique of its own since it has slightly different results compared to topping (recovery time, number of colas produced in one cut, etc.).
When topping your cannabis, you cut off a growing node of the plant, reducing the height instantly. This can be especially beneficial if you’ve let your plant get too tall. Topping also increases the number of colas, which can give you more bud at harvest,
Once flowering is fully underway (after the initial flowering stretch), the plant will not grow much taller, so you can just try to hang on until harvest. Sometimes you may even have to harvest a particularly tall cola ahead of time to prevent it from getting bleached or burned. Don’t stress, it happens to us all! I recommend trying to take it as a learning experience 🙂
Topping and FIMing are two cannabis plant training techniques that involve “pinching” or cutting off some of the top growth. These techniques are designed to give you a free way to achieve better plant shape (to make better use of the available light), create more colas, and achieve bigger yields.
