There are many methods for cannabis plant training that can help increase yields and maximize your space. Low-stress training, mainlining, and super cropping are some examples of plant training methods. Topping, Fimming, and defoliation are some of the options. Your preferences and experience will determine the training method you choose, but “topping” is a basic method for improving yields.
What is “topping” cannabis?
Topping cannabis is a method of training cannabis plants to increase their lateral growth and yield more. If cannabis is allowed to grow naturally, it will produce one main stalk, also known as cola. There are a few smaller stalks around it. These smaller stalks can produce tiny buds that can have a significant impact on the overall quality of the harvest.
You can “topper” certain sections of the plant to increase its production of colas. The ability to sustain more buds and a stronger plant structure is a result of having more cola.
Topping vs. Fimming
Two methods are discussed together – topping and Fimming.
Topping is the most common method of training large outdoor growers. They will repeat this process several times to achieve large plants. This method tends to produce a stronger plant that needs less support. Fimming is a great option for those who live in small spaces and want to maximize their yield. These plants will require additional support, so it is a good idea to trellis your garden.
Top cannabis plantations
Fimming and topping are both training methods, but they differ in their stress levels. Topping is a high-stress method that distributes growth hormones from one cola to several colas. This allows for a higher-yielding plant and a greater size. Fimming, a lower-stress method that can produce more cola, will require structural support.
To make sure your plant flowers properly, you must fim the vegetative stage of the plant before topping. The best time to fim cannabis plants is when they have developed at least 3-5 nodes. Topping is usually done at 4-6 nodes. To ensure that the plant can be topped, these nodes must all be healthy and have vibrant colors.
Step 1 – Preparation
Preparing for topping is the first step. A pair of scissors or a razor blade is needed. They should be sharp enough to avoid tearing and disinfecting before being used.
Step 2 – Make the cut
Topping involves removing any new growth from the main stem. Fimming is slightly different in that you can top the plant by cutting lower. This means that the plant will produce two new strong stalks where you have cut.
When combined with topping, low-stress training can create more colas. Fimming results in 3-8 new stalks but the plant won’t be as supported.
Step 3 – Observe
You need to keep an eye on the plant’s progress after you have topped it. You may notice lower branches “catch up”, as energy is distributed more evenly. The process may take several weeks to complete. Once the plant is fully recovered, you can retop to achieve the desired structure.
How long should you wait to top your marijuana plants?
Let your marijuana plants mature for at least 4-6 weeks before you cut them. Once they have reached the vegetative stage, you can move them to a larger container.
It’s easy for a plant to know when it’s time to be removed once it has at least two to five nodes.
This method is preferred by many growers as it is simpler to comprehend and gives you more assurance that your plants are ready for topping.
