Pruning cannabis - a guide to increasing yield and excellent quality

Pruning cannabis plants is a topic that describes an essential practice of growers to both maximize yield and improve the quality of their plants. Through targeted pruning techniques, plant growth can be optimally controlled, resulting in stronger plants and more abundant flowers.

This article is a well-founded contribution that gives you tips on how best to carry out pruning in cannabis cultivation, even if you don't have green fingers.

Pruning your cannabis plants offers numerous advantages that have a positive effect on both the health of the plant and the harvest. Targeted pruning ensures more vigorous growth, better light distribution and can significantly increase the yield.

By selectively removing certain parts of the plant, the plant can direct its energy towards developing larger and denser flowers. Particularly with bushy plants, which develop many smaller branches and leaves, the energy may be over-distributed.

By pruning weak or excess shoots, the remaining buds are specifically supplied with nutrients. The result is stronger, more compact buds with a higher potency.

Better light penetration ensures that even lower-lying flowers receive sufficient sunlight or artificial lighting. When the light hits all parts of the plant evenly, the flowers develop more homogeneously and produce more valuable terpenes and cannabinoids.

This not only ensures a more intense aroma, but also improves the structure of the buds. It also prevents the formation of inferior, airy buds with less potency.

A well-ventilated plant is more resistant to mold and pests. Removing excess leaves improves air circulation between the branches, allowing moisture to evaporate more quickly. This measure is particularly important for indoor cultivation, where stagnant air and high humidity can cause problems.

Another advantage: the improved air circulation also reduces the risk of overwatering cannabis. If leaves grow too densely, the plant often stores too much water, which can lead to root rot. A well-aerated plant absorbs moisture more evenly and stays healthy.

Especially in indoor cultivation, where the height of the plants is limited, pruning ensures better control over growth. A plant that grows uncontrollably in height can quickly exceed the available space and impair the distribution of light.

By selectively removing the upper shoots, the plant grows bushier and develops several main shoots. This not only produces more flowers, but also a more compact plant that is easier to care for. Structured growth also makes regular inspection and care easier, so that problems can be identified and rectified at an early stage.

Pruning is therefore far more than just a method of increasing yield - it is an important step in strengthening the plant, preventing disease and maximizing the quality of the harvest.

There are different technologies or pruning methods to shape cannabis plants, each with their own benefits and applications. Choosing the right method depends on your goals and the specific situation.

Topping involves removing the upper main stem of the cannabis plant in order to divide it and promote the development of side shoots. Instead of one dominant tip of the plant, this results in several main shoots, which makes the plant grow bushier and increases the overall yield. This method is particularly suitable for indoor cultivation, as it limits the height of the plant and allows a more even distribution of light.

To carry out topping, the hemp plant should be in the vegetative phase and ideally have already developed 3 to 5 nodes (nodal points). At this stage, it is strong enough to regenerate quickly. It is important to use sharp, disinfected scissors or a knife to avoid infection. The cut is made directly above a node so that the side shoots underneath grow stronger. In the following days, the plant regenerates and develops several equal shoots, which increases the number of inflorescences.

Fimming is a variant of pruning that was discovered by chance - hence the name "FIM" ("Fuck, I Missed"). In contrast to classic topping, the entire main shoot is not removed, but only part of the fresh growth at the tip is cut off. This results in several new shoots forming at the cut point, which makes the plant grow even bushier.

This method is best used in the early vegetative phase, when the hemp plants are still actively growing. When pruning, around 75% of the new leaf tips are removed, which slightly slows down the growth process, but at the same time redistributes it. The plant responds by forming several new side shoots, resulting in a more compact structure and potentially higher yields. After pruning, the plant should be given a few days to recover before further pruning is carried out.

Lollipopping cannabis is a method in which the lower branches and leaves are removed in order to concentrate all the plant's energy on the upper flowering areas. The name comes from the resulting shape of the plant, which resembles a lollipop after pruning - with a dense, flower-rich upper area and a free lower part.

Lollipopping should be carried out in the late vegetative phase or at the beginning of the flowering phase to ensure that the plant can still recover. When pruning, the lower 20 to 30 % of the branches and leaves are removed, especially those that are in the shade and contribute little to flower production. This not only improves light distribution, but also air circulation, which reduces the risk of mold and pest infestation. After lollipopping, the plant should be well cared for and provided with sufficient water and nutrients to minimize stress and promote flower development.

Defoliation also improves light penetration and air circulation by specifically removing large cannabis leaves. This ensures that all parts of the plant are evenly exposed to light and optimizes the growth of the flowers. At the same time, the risk of mold and pest infestation is reduced as less moisture collects between the leaves.

The best time for defoliation is in the middle vegetative phase or at the beginning of flowering, when the plant can still regenerate well. Leaves that obscure the flowers or hinder air circulation are removed. This should be done carefully so as not to stress the plant too much. After pruning, the plant needs a few days to recover while it efficiently distributes its energy to the remaining flowers.

Mainlining is a technique used to form a symmetrically branched plant with several main shoots. This ensures that all buds receive the same amount of light, resulting in a high yield. This method is ideal for indoor cultivation, as it keeps the plant compact and controls its height growth.

To do this, the main shoot is cut off above the third or fourth node to encourage the growth of two equal side shoots. These are fixed horizontally to create a symmetrical structure. The process can be repeated until the desired number of main shoots is reached. The result is a plant with evenly developed inflorescences and optimum energy distribution.

Supercropping is a stress technique that controls height growth and makes the plant more stable. By gently bending the branches without breaking the outer tissue, the stem thickens, which increases resistance and makes it easier to carry heavy flowers. The technique also promotes resin production.

Supercropping is one of the methods that can be used during the vegetative phase, when the plant is still flexible. The affected branches regenerate within a few days and grow back stronger. Indoor growers use this technique specifically to steer growth in a horizontal direction and improve light utilization. This leads to better flower formation and increases the overall quality of the harvest.

The right time to prune your cannabis plants is crucial to minimize stress and achieve optimal results.

During this growth phase, the plant regenerates quickly and can be structurally adapted. Pruning promotes bushy growth and the development of several main shoots. Topping or fimming is ideal to increase the yield. At the same time, removing excess leaves improves air circulation and reduces the risk of overwatering.

Flower formation begins at this stage, which is why only light pruning is advisable. Large fan leaves that shade the buds can be removed. Lollipopping concentrates the energy on the upper flowers. Excessive pruning should be avoided at this stage as it causes stress and can have a negative impact on bud development.

The plant is now focusing on ripening the flowers, which is why major interventions should be avoided. Only yellowed or heavily shaded leaves can be removed. Radical pruning could reduce the resin content and impair the quality of the flowers. Now is the time to be patient and prepare for the harvest.

There are numerous advantages to pruning cannabis that have a positive effect on yield and quality:

• Increased yield: Targeted pruning allows the plant to grow bushier and produce more buds.

• Better light penetration: All parts of the plant receive sufficient light, which improves growth.

• Improved air circulation: Fewer leaves ensure better ventilation, which prevents mold and disease.

• Stronger plant structure: The plant develops more robust branches that can carry more weight.

• Uniform growth: The growth of the plant can be controlled, which is particularly advantageous for indoor cultivation.

• Higher quality flowers: A well cared for plant produces dense, resinous buds with an intense aroma.

The right tools are essential for efficient and safe pruning:

• Sharp shears or secateurs: For precise and clean cuts without unnecessary stress for the plant.

• Disinfectant: For cleaning tools to prevent the transmission of disease.

• Gloves: Protect hands from resin deposits and ensure hygienic working conditions.

Many beginners make typical mistakes when pruning, which can affect the yield and quality of the plants:

• Excessive pruning: Too many cuts at once can stress the plant and inhibit growth.

• Unsuitable tools: Blunt scissors can bruise the stems and promote infections.

• Wrong timing: Pruning too late during the flowering phase can have a negative impact on the growth of the flowers.

• Do not disinfect tools: unclean scissors can transmit diseases.

• Random pruning without technique: Inconsiderate pruning can have an uncontrolled influence on growth.

• Do not allow sufficient recovery time: Plants need time to regenerate after each cut.

Experienced cannabis growers swear by targeted pruning techniques to achieve the best results.
