In this post I would like to talk about types of pruning and how we can apply them to our marijuana plants.

We will look at how to do the following techniques: LST, Supercropping, bottom pruning, apical pruning and, finally, I will mention FIM pruning.

Each plant adapts better to one type of pruning and that will be a decision left up to each grower based on the grow space and also the demands of the plants, keeping in mind the fact that all kinds of pruning and cutting that we do to our plants should always be with previously sterilized materials (alcohol cleaning).


Lst Pruning (Low Stress Training)


LST is a pruning technique for marijuana plants that basically consists of tying stems together in order to redirect them in the direction that is best at any given moment. That way, we allow other stems to take their place, making for a leafier growth and increasing flower production in each plant.

You should keep in mind the fact that not all string works for this. It’s advisable to make sure that the string you use doesn’t damage the stem of the plant.

This way of controlling the vegetation of your plants can be used repeatedly in crops that need to be kept discretely, given that we can make it such that our plant spends a lot of its growing phase horizontally.



This technique can’t be considered pruning, though using it we are able to direct or stop growth of our marijuana plants according to our needs at any given moment.

Supercropping consists of choosing a part of the plant whose growth you want to slow down and, very carefully, taking this part of the trunk between your fingers and then bending, and squeezing it until you feel a slight crunch. At first it may seem as though this technique is very aggressive, but you will find that afterwards the stem which is now less erect, recuperates the following day, creating a small callous and allowing the stems below it to grow more vigorously.

This process can be done as much in the growing phase as at the beginning of flowering. In the final phase of flowering you can no longer redirect any sort of growth, since the plants are focused on maturing their flowers.

Bottom pruning


Bottom pruning is one of the most used techniques by all interior growers, since if the technique isn’t applied it can drastically reduce the yield and make it such that a large part of the harvest is small flowers. If you don’t want to have this problem, the solution is to prune the bottom portions.

Well done low pruning consists of removing 5 to 8 bottom branches, according to the size of the marijuana plants that you are growing, during the first phase of flowering, before reaching 20 days of flowering.

This way you can make it such that the flowers that have already begun to form have more energy, considerably increasing their size.

Apical pruning


Apical pruning is one of the best known methods by growers, since it was one of the first known, perhaps because of the final result that it provides in forming two “central” buds in the same plant.

This technique consists mainly of cutting the upper part of the stem of the plant, between the first and second stations, without cutting the two young sprouts that you find on each station of the plant.

These two sprouts begin to increase their growth in days and that the production of flowers increases in your marijuana plants. This type of pruning is recommendable in the growing phase, since that way you allow plenty of time for the two sprouts to grow to a considerable size.


FIM Pruning (Fuck I Missed)


This technique was discovered accidentally when its creator tried to do apical pruning and left behind a small part of the upper node. After a few days he noticed that several new sprouts emerged from which grew new branches.

Doing FIM is simple. All you have to do is cut 80% of the upper node on your cannabis plant at an angle (similar to apical pruning). If you do the cut right, in a few days you will see new sprouts emerging.

For something new, this time I would like to ask all of our readers a questions to which they can respond in our blog commentaries:

Which of these pruning techniques seems the best to you?

Thank you for another week of reading, and good smoke to all of you.
