Leaf Production Optimization

Leaf-Focused Management:

• Remove lower leaves that touch growing medium (prevent disease)
• Maintain healthy leaf canopy for maximum photosynthesis
• Focus on young to medium-aged leaves (highest andrographolide content)

Flower Management:

• Allow some flowers to develop (complete compound profile)
• Remove excess flowers to maintain leaf production focus
• Harvest timing critical – peak compounds just before full flowering

Harvesting for Maximum Therapeutic Potency

Optimal Harvest Timing

Peak Andrographolide Indicators:

• Plant age: 12-16 weeks from seed (varies with growing conditions)
• Flowering stage: Just before or during early flowering
• Bitterness test: Leaves should be extremely bitter to taste
• Visual indicators: Healthy, dark green leaves with no yellowing
• Time of day: Early morning (2-4 hours after sunrise) when compounds peak

Environmental Timing:

• After controlled stress period: 2-3 weeks of slight water/nutrient stress
• Cool weather: If growing in natural conditions, cooler weather increases compounds
• Before seed set: Harvest before plants put energy into seed production

Harvesting Techniques

Whole Plant Harvest (Maximum Yield):

• Cut entire plant 2-3 inches above growing medium
