Combine representative bract trichomes, floral development, stigma condition, senescence, genotype, canopy position, and mold inspection rather than relying on one calendar week or stigma color alone.
FlowersMulti-signal flower maturity and risk inspection checklist
Interactive academic visual
Maturity & risk inspection
Use several maturity signals while actively checking for flower-health risks
Trichome observations
Use standardized bract sampling and magnification as one developmental observation, not a laboratory potency measurement.
Knowledge check
Can you explain what the visual is showing?
Practice
Why should flower maturity not be judged from stigma color alone?
