High-Yield Training Techniques
To maximize yield and quality, certain low-stress and high-stress training (LST & HST) methods can be applied:
A. SCROG (Screen of Green)
- Encourages horizontal growth, allowing even light penetration.
- Reduces popcorn buds and maximizes yield per square foot.
B. LST (Low-Stress Training)
- Bending branches gently to improve airflow and light distribution.
- Increases bud sites without stressing the plant.
C. Topping & FIMing
- Topping (cutting main cola) results in multiple colas instead of one.
- FIMing (partial cut of new growth) enhances bushier growth.
D. Defoliation (Selective Pruning)
- Removes lower fan leaves to boost airflow and prevent mold.
- Increases the amount of light that reaches the lower bud locations.
Harvesting and Post-Harvest Processing
A. Trichome Maturity and Harvest Timing
- Harvest when trichomes are milky white for maximum potency.
- Amber trichomes indicate more sedative effects.
B. Curing for Enhanced Flavor and Potency
- Dry buds slowly at 60°F (15°C) and 50% RH for 7-14 days.
- Cure in airtight jars, burping daily to enhance terpene retention.
