The ideal time to harvest depends on the strain and personal preference. Fast-maturing strains like Indicas might be ready in 40 days of flowering, while Sativas could take up to about 100 days
Visually, without a magnifying glass, the buds should be swollen,
and the pistils partly oxidized (brown).
Under zoom, if the trichomes are still clear, wait
harvest when you see a milky/amber mix.
The maturation time given by breeders, from the first pistil to harvest, is a good guideline. For example, if you have a Skunk with a theoretical harvest on day 55, and the first white pistil appears on day 10 of flowering, aim to harvest around day 65 of flowering. Similarly, if you have a Haze meant to be harvested in 10 weeks, and the first pistil appears after 2 weeks of 12/12 light schedule, plan to harvest around the 9th week of the 12/12 light schedule.
