How to fim cannabis

When you see your plant thicken connections like this, it means that the plant is strengthening the “internal system” of the stem, so it’s easier to deliver nutrients and other building blocks. This results in faster growth, bigger colas, and increased yields for each of the affected stems.

Topping and FIMing techniques should only be used in the vegetative stage! In fact, any training technique that involves cutting or damaging your plant should optimally be done in the vegetative stage of cannabis growth, before the flowering/budding stage begins.
Lower growth nodes will become new colas once they’re exposed to light and air, but they develop much faster when the main cola’s dominance is broken by topping or FIMing

If you’re still in the vegetative (non-budding) stage and plants are growing way too tall, you can top the plant immediately to remove height as needed. The time spent growing the extra growth will be lost, so this may add time to the veg stage.
These plants were FIMed early in the vegetative 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.).

With Fimming, you can get less consistent results than with topping. If you don’t actually pinch off the top growth just right, you may end up with only 2 or 3 colas instead of 4.

If you want to top the plant multiple times, you may be interested in learning about main-lining (creating a manifold – a plant training technique).

Topping and FIMing are two plant training techniques that involve "pinching" or cutting off some of the top growth of your plant. These techniques are designed to give you a free way to achieve better plant shape (to make better use of the available light
