Welcome to the realm of advanced cannabis cultivation! If you’re reading this, you’re likely no stranger to the basic principles of growing cannabis. But today, we delve deeper into the art and science of pruning and training. Mastering these techniques can be a game-changer, pushing your plants to produce bountiful, high-quality yields.
Understanding Basic Pruning
Before we jump into the complex stuff, let’s ensure we’ve got the fundamentals down. Pruning, in its essence, is about removing unwanted parts of the plant. This includes dead or yellow leaves, excess branches, and non-productive buds. The goal? To redirect the plant’s energy towards growing robust flowers and improving overall health. Remember, pruning should be a routine during the vegetative stage, preferably during cooler times of the day to minimize stress.
Tools for Effective Pruning:
- Pruning Shears: Your go-to for snipping small branches and leaves.
- Hand Pruners: Ideal for tackling larger branches.
- Scalpels: For those precise cuts, especially when you’re targeting single leaves.
Advanced Pruning Techniques
Topping:
- Explanation: Topping involves cutting off the top of the cannabis plant’s main stem. This technique is used to stop the vertical growth and encourage the plant to grow more horizontally, creating a bushier plant with more bud sites.
- Steps:
- Identify the top of the main stem, which is typically the newest growth.
- Using sterilized pruning shears, make a clean cut above the node (where leaves and branches extend from the stem).
- Remove the top part of the stem just above the node.
Fimming:
- Explanation: Fimming is similar to topping but less precise. Here, you remove about 50-75% of the top of the main stem. This can lead to four new main colas instead of the two typically produced by topping.
- Steps:
- Locate the top of the main stem, focusing on the newest growth.
- Partially cut the top, removing only a portion of it.
- Ensure that about 50-75% of the top is removed.
Lollipopping:
- Explanation: Lollipopping is a pruning technique where the lower branches and leaves of the cannabis plant that receive little to no light are removed. This process directs the plant’s energy towards the top part, which receives more light, thereby enhancing the growth and quality of the buds on the upper branches.
- Steps:
- Examine your plant and identify the lower third portion, which typically receives the least light.
- Carefully remove the smaller branches and leaves in this lower section using pruning shears or hand pruners. The goal is to ‘clean’ the lower part of the plant.
- Be mindful not to strip too much off at once – aim for a gradual process over a few days if necessary.
Training Techniques for Enhanced Growth
Low-Stress Training (LST):
- Explanation: LST involves bending and tying down the branches to change the plant’s shape without cutting. This technique promotes even light exposure and airflow, leading to increased yield.
- Steps:
- Gently bend the branches away from the center of the plant.
- Use soft ties or plant tape to secure the branches in their new positions.
- Adjust the branches periodically to maintain an even canopy.
Super Cropping:
- Explanation: Super cropping is a high-stress training technique where you intentionally damage the stems to encourage new growth. This method creates stronger, more resilient plants.
- Steps:
- Choose a healthy branch and locate a spot just below a node.
- Gently squeeze and twist the stem until you feel the inner fibers break, but do not completely sever the stem.
- Bend the damaged part of the stem to encourage new growth.
Monster Cropping:
- Explanation: Monster cropping involves taking clones from a plant that’s already in the flowering stage and reverting them back to the vegetative stage. This results in extremely bushy plants with a large number of branches and potential bud sites.
- Steps:
- During the third week of the flowering stage, select healthy branches to clone.
- Cut these branches at a 45-degree angle, then place them in a rooting medium.
- Once the clones develop roots, revert them back to the vegetative stage under appropriate lighting.
Advanced Training Methods
Screen of Green (SCROG):
- Explanation: SCROG involves using a screen or netting to train your cannabis plants to grow horizontally. This method maximizes light exposure and supports heavy buds.
- Steps:
- Place a screen or net above your plants at a suitable height.
- As the plants grow, weave the branches through the screen.
- Adjust and spread the branches to cover the screen evenly.
Main-Lining:
- Explanation: Main-lining combines topping and LST to create a manifold that allows the plant to distribute energy evenly across all branches.
- Steps:
- Top the plant to create two main branches.
- Train these branches to grow horizontally using LST.
- As secondary branches grow, repeat topping and training to create a symmetrical, manifold structure.
Optimizing Growth and Yield
Flushing:
- Explanation: Flushing is the process of clearing out the nutrients from the soil or growing medium a few days to weeks before harvest. This improves the taste and quality of the buds by removing excess salts and nutrients.
- Steps:
- Begin flushing 1-2 weeks before the anticipated harvest date.
- Water the plants with plain pH-balanced water only.
- Monitor the plants for signs of nutrient deficiencies to ensure the timing is correct.
As you journey through these advanced techniques, remember that each plant is unique. Observe, experiment, and adapt these methods to suit your specific growing environment and strain. The path to mastering cannabis cultivation is filled with trials and triumphs. Embrace each learning opportunity and watch your garden flourish like never before.
