LST and HST: Training techniques for maximum yields

Plant Training maximises cannabis yields by manipulating growth. Low Stress Training (LST) and High Stress Training (HST) explained:

**Low Stress Training (LST)**

Gentle methods without cutting or injuring the plant.

*LST techniques:*

- **Bending and fixing**: Carefully bend the main shoot to the side, fix with wire or string

- **SCROG (Screen of Green)**: Stretch net over plants, thread shoots through meshes

- **Supercropping**: Carefully bend shoots without breaking them (border area to HST)

*LST advantages:*

- No stress for the plant

- Even light distribution

- More inflorescences at the same height

- Perfect for beginners

**High Stress Training (HST)**

Methods with cuts or deliberate injuries.

*HST techniques:*

- **Topping**: Cutting the main shoot, leads to 2-4 new main shoots

- **FIMing**: "F*ck I Missed" - incomplete topping for 4-8 new shoots

- **Lollipopping**: Remove lower branches and leaves, energy to main colas

- **Defoliation**: Strategic removal of leaves for better light penetration

*HST timing:*

- Apply only in vegetative phase

- At least 1 week recovery before flowering initiation

- Healthy, vigorous plants are a prerequisite

**Combination strategies:**

1. Topping in week 3-4

2. LST from week 5

3. SCROG in preparation for flowering

4. Lollipopping before flowering

**Important rules:**

- Use clean, sharp tools

- Never use on diseased or stressed plants

- Allow sufficient recovery time

- Less is often more - do not overdo it
