Whether they cultivate cannabis indoors, outdoors or in greenhouses, many growers like to apply various training or pruning techniques in order to maximise the yield of their plants and thus obtain the most abundant harvest possible. These types of techniques can be of high impact and cause stress, such as pruning (where some part of the plant is cut, no matter how small) or low stress, with less negative impact. A perfect example of the latter would be Low-Stress Training, where the branches of the plant are tied so that it grows with a structure determined by the grower, but where there is no pruning or cutting of the plant, it is simply guided in its structural development.
Today we are going to discuss a high-stress technique - because it involves pruning - although as you will see it differs slightly from the classic apical pruning or topping, as it is usually called. What we're talking about is the FIM pruning technique, with which we will achieve even greater development of new buds and lateral branches than that achieved with the tried and tested technique of apical pruning. Let's see what this it's all about!
