Advanced Plant Care & Training Techniques
Proper plant training and care techniques are essential for maximizing yields, improving plant health, and managing garden space efficiently.
Fundamental Training Methods
Topping Technique
Purpose: Redirects plant energy from vertical to lateral growth, creating multiple main colas and a bushier plant structure.
Timing: Perform during vegetative stage after plant develops 3-5 nodes and establishes a strong root system (usually 3-4 weeks from germination).
Method: Using sterilized sharp scissors, cut just above a node where new growth emerges. This removes apical dominance and encourages lateral branching.
Recovery: Allow 7-10 days between topping sessions. Plants may show slight stress initially but will resume vigorous growth.
Strategic Pruning
Selective Defoliation: Remove large fan leaves that block light penetration to lower branches and developing bud sites.
Timing Considerations: Light pruning throughout vegetative growth, moderate pruning in early flowering (weeks 1-3), minimal pruning after week 4 of flowering.
Benefits: Improved light distribution, better air circulation, reduced mold risk, and energy redirection to productive growth.
Technique: Remove no more than 20% of foliage at one time. Focus on older, yellowing, or damaged leaves first.
Low Stress Training (LST)
Concept: Gently bend and secure branches to create an even canopy without cutting or damaging the plant.
Implementation: Use soft plant ties or LST clips to gradually bend branches outward, exposing more bud sites to light.
Benefits: No recovery time needed, suitable for autoflowering varieties, creates multiple main colas.
Maintenance: Adjust ties regularly as plants grow, ensuring no branches are restricted or damaged by tight ties.
Super Cropping
Advanced Technique: Carefully damage the internal structure of branches without breaking the outer skin to control height and increase yields.
Method: Gently squeeze and bend branches until you feel the internal fibers break, then support the branch as it heals.
Recovery: Plants typically recover within 3-7 days and often show increased vigor at the bend point.
Caution: Practice on less important branches first. Not recommended for beginners or autoflowering varieties.
Advanced Training Systems
SCROG (Screen of Green)
Setup: Install horizontal screen or net 20-25 inches above growing medium. Use fewer plants (1-4) with longer vegetative period.
Space Requirements: Allocate 3-4 square feet per plant to allow full canopy development through the screen.
Management: Weave branches through screen openings, maintaining even canopy height. Continue training until screen is 75% full.
Benefits: Maximizes light efficiency, creates uniform cola development, ideal for limited height spaces.
SOG (Sea of Green)
Concept: Use many small plants (1-2 square feet each) with minimal training to create a canopy of uniform colas.
Plant Count: Higher plant count with shorter vegetative time. Switch to flowering when plants are 12-18 inches tall.
Container Size: Use smaller pots (1-3 gallons) as plants don't need extensive root systems.
Advantages: Faster harvest cycles, reduced vegetative time, uniform cola development, easier management.
Advanced Defoliation (DEFOL)
Strategic Timing: Major defoliation sessions at day 1 of flowering and day 21 of flowering for maximum benefit.
Technique: Remove fan leaves that don't contribute to energy production, focusing on interior and lower growth.
Benefits: Improved light penetration, better air circulation, larger bud development, reduced larfy (small, underdeveloped) buds.
Recovery: Plants typically recover within 3-5 days and show increased flower production.
Lollipopping Technique
Method: Remove all lower growth below the canopy level to create "lollipop" shaped plants with energy focused on top colas.
Timing: Perform during early flowering (weeks 1-2) to redirect energy before buds fully develop.
Benefits: Eliminates small, low-quality buds; concentrates energy on main colas; improves air circulation at plant base.
Maintenance: Monitor for new lower growth throughout flowering and remove as needed.
