Low Stress Training Guide

Introduction

Low Stress Training (LST) is a cultivation technique used by cannabis growers to maximize yields and optimize plant health. Unlike more invasive methods, LST involves gently manipulating the plant's growth pattern without causing significant harm or stress. This method is particularly popular among home growers and those cultivating cannabis in limited spaces, as it encourages bushier plants with multiple colas, leading to increased production.

The Science Behind LST

Cannabis plants naturally grow in a Christmas tree shape, with one main cola dominating the top and smaller buds forming on the lower branches. This vertical growth can lead to uneven light distribution, where the top cola receives the most light and the lower branches get less, resulting in lower yields.

LST involves bending and securing the plant's branches to create a more even canopy. This even canopy allows all parts of the plant to receive equal light exposure, promoting uniform growth and larger yields. The main principle behind LST is to manipulate the plant's phototropism—its growth response to light—by directing the growth hormones (auxins) to lower branches, encouraging them to grow as vigorously as the main cola.

Benefits of LST

1. Increased Yields: By creating multiple colas and ensuring even light distribution, LST can significantly increase the overall yield of a cannabis plant.

2. Better Light Penetration: An even canopy allows light to penetrate deeper into the plant, benefiting lower branches and buds.

3. Improved Airflow: Spreading out the branches improves airflow around the plant, reducing the risk of mold and pest infestations.

4. Space Efficiency: LST is ideal for growers with limited vertical space, as it encourages horizontal growth and prevents plants from becoming too tall.

5. Stress Reduction: As the name suggests, LST is less stressful to the plant compared to other techniques like topping or super cropping, which involve cutting or pinching the plant.

How to Perform Low Stress Training

Materials Needed

• Soft plant ties (garden wire, twist ties, or pipe cleaners)
• Stakes or anchor points
• Patience and gentle hands

Step-by-Step Guide

1. Identify the Main Stem: Start when the plant is young and has at least four to six nodes. Identify the main stem and the branches you wish to train.

2. Bend the Main Stem: Gently bend the main stem downwards and secure it to the edge of the pot or to an anchor point using a soft plant tie. Be careful not to snap or damage the stem.

3. Secure Side Branches: As the side branches grow, gently bend them outwards and secure them in place. This encourages the plant to spread out horizontally.

4. Adjust and Reposition: Regularly check the plant and adjust the ties as needed. As the plant grows, reposition the branches to maintain an even canopy.

5. Prune if Necessary: Remove any large fan leaves or small growths that block light to the lower branches. This step is optional but can help improve light penetration.

6. Monitor and Maintain: Continuously monitor the plant for signs of stress or damage. Adjust ties and reposition branches as the plant grows.

Tips for Successful Low-Stress Training (LST)

• 1. Start Early:
  Begin LST when the plant is young and its stems are still flexible. This is typically in the early vegetative stage. Younger plants are easier to bend and manipulate without causing damage. As the plant matures, its stems become woody and rigid, making them more susceptible to snapping or breaking during training.

  2. Be Gentle:
  Handle the plant with care to avoid causing stress or injury. When bending stems, do so slowly and gradually. Sudden movements or applying too much force can snap branches or damage the main stem, which can hinder the plant’s growth and recovery.

  3. Use Soft Ties:
  Select soft, flexible ties such as garden wire, soft plant ties, or even pipe cleaners. These materials are gentle on the plant and can be adjusted easily without cutting into the stems. Avoid using materials like string or fishing
