Understanding Autoflowering Cannabis Plants
Autoflowering cannabis plants have a predetermined life cycle and transition from the vegetative stage to the flowering stage based on age rather than light cycles. They typically have a shorter growth period and tend to be smaller in size compared to photoperiod strains. These characteristics influence the pruning techniques employed for autoflowering plants.
1. LST (Low Stress Training)
LST is a popular technique for training autoflowering cannabis plants without causing stress or stunting their growth. Here's how to perform LST on autoflowering plants:
-
Bending and Securing: Gently bend the main stem of the plant in a horizontal direction to create a more even canopy. Use soft plant ties or gardening clips to secure the branches in place without causing damage.
-
Promoting Light Exposure: By bending the main stem and lower branches, LST helps expose more bud sites to light, promoting better growth and higher yields.
2. Topping
Topping is a technique that involves removing the top growth tip of a cannabis plant to encourage lateral growth and the development of multiple colas. However, topping can be challenging with autoflowering plants due to their limited vegetative phase. If using this technique on autoflowering plants, it's crucial to do it early in the vegetative stage, when the plant has at least three to four nodes. Be mindful that topping may temporarily slow down the growth of autoflowering plants, so it's recommended to experiment cautiously.
3. Defoliation
Defoliation, the selective removal of leaves, can be applied to autoflowering plants to improve light penetration and airflow. Here are some considerations when defoliating autoflowering plants:
-
Minimal Leaf Removal: Due to the shorter life cycle of autoflowering plants, it's essential to be conservative when defoliating. Avoid removing too many leaves at once to prevent stress and ensure the plant has enough foliage to support its growth.
-
Focus on Lower Leaves: Prioritize the removal of lower leaves that receive less light and may not contribute significantly to bud development. This allows better light penetration to reach the lower parts of the plant.
-
Timing: Perform defoliation during the early flowering stage when the plant has developed some bud sites, but be cautious not to remove too many leaves, as this can impact the plant's ability to photosynthesize and produce energy.
4. Lollipop Technique
The lollipop technique involves removing the lower branches and foliage of the plant to focus energy on developing larger, topmost buds. Here's how to apply the lollipop technique to autoflowering plants:
-
Identify Lower Branches: Identify the lower branches that receive less light and have smaller bud development potential.
-
Remove Lower Foliage: Carefully remove the lower leaves and branches, leaving the upper part of the plant intact.
By removing lower branches, the lollipop technique encourages the plant to direct its energy toward producing larger and denser buds in the top canopy.
Pruning autoflowering cannabis plants requires an understanding of their unique growth patterns and limitations. Techniques such as LST, topping (with caution), defoliation, and the lollipop technique can be applied to promote better light exposure, airflow, and overall bud development. Remember to exercise caution, avoid excessive pruning, and observe the plant's response throughout its short life cycle. With proper pruning techniques, autoflowering cannabis plants can thrive and produce bountiful yields.
