The perfect harvest time determines potency and effect. Read trichomes correctly and find the optimum harvest time.
Determining the optimum harvest time is crucial for potency, flavour and effect:
**Trichome examination (main indicator):**
*Trichome stages:*
- Clear/transparent: immature, low THC levels
- Milky/cloudy: Peak THC, energetic effect
- Amber coloured: THC converts to CBN, relaxing effect
- Optimal: 70-80% milky, 20-30% amber
*Trichome examination:*
- 60x magnifying glass minimum for field inspection
- 100x+ microscope for detailed analysis
- Smartphone macro lenses as a budget option
- Inspect multiple flower areas
- Evaluate main colas and side shoots separately
*Observe trichome distribution:*
- Upper flowers ripen first
- Lower areas take longer
- Staggered harvest possible
- Achieve different effects
- Whole plant vs. area harvest
**Pistil development (secondary indicator):**
*Pistil stages:*
- White, erect hairs: Early flowering
- 50% brown/orange: Mid-flowering
- 70-90% brown: Harvest window
- 100% brown: Possibly overripe
*Pistil assessment:*
- Look at main colas
- New white pistils = not ready yet
- Retracted pistils in Calyx
- Genetics-specific differences
- Consider environmental influences
**Calyx swelling:**
*Signs of maturity:*
- Calyx swells significantly
- "Foxtailing" normal for some varieties
- Flowers feel firm and compact
- Resinous, sticky surface
- Intense odour reaches peak
**Variety-specific timing:**
*Indica-dominant varieties:*
- Often 7-9 weeks flowering time
- Faster trichome development
- Compact, dense flowers
- Less foxtailing
- Clear maturity signals
*Sativa-dominant varieties:*
- 9-14 weeks flowering time
- Slower trichome development
- Airier flower structure
- More frequent foxtailing
- Patient approach required
*Autoflower varieties:*
- 8-12 weeks total
- Less clear signs of maturity
- Grower specifications as a guideline
- Often earlier harvest optimal
- Trichomes most important indicator
**Effect according to harvest time:**
*Early harvest (more clear trichomes):*
- Energetic, cerebral effect
- Less sedating
- Higher THC-V levels possible
- Suitable for daytime use
- Less couchlock
*Standard harvest (milky trichomes):*
- Balanced High
- Peak THC content
- Euphoria and relaxation
- Versatile effect
- Mostly optimal timing
*Late harvest (amber trichomes):*
- Highly relaxing/sedative
- CBN-rich (from THC breakdown)
- Sleep-inducing
- Pain-relieving
- Evening/night use
**Consider environmental factors:**
*Mould risk:*
- High humidity = harvest earlier
- Poor ventilation = risk increases
- First signs of mould = harvest immediately
- Dense flowers more susceptible
- Safety before perfection
*Light degradation:*
- UV light breaks down THC
- Reduce strong lighting late in flowering
- Observe natural sunlight outdoors
- Protect trichomes from light burn
**Harvest preparation:**
*Flushing:*
- 1-2 weeks before planned harvest
- Only give pH-corrected water
- Remove excess nutrients
