Outdoor crops that cannot be protected should be harvested if there is a chance of frost or a violent storm. Indoors or outdoors, harvest in the morning whenever possible. When harvesting the Sativa variety, there is one extremely crucial quality: patience. In the experience of most expert growers, sativa-dominant hybrids are usually ready to harvest 70-77 days after their flowering cycle.
On the other hand, pure Sativa strains, as well as specific sativa dominant hybrids, may need 83 to 98 days to finish and be ready for harvest. The first way to approach harvest time is to look at the type of strain. You must harvest Indica strains before Sativa strains. The harvest time for Indicas takes eight weeks after flowering and Sativa varieties ten weeks after flowering.
However, it should also be noted that this indicator is strain-specific. For example, pure Sativa and sativa dominant strains are best harvested when most trichomes are still milky white in color. Pure indicas and indica-dominant strains are best harvested after at least some of the trichomes have turned amber in color. But if you wait too long and allow the trichomes to degrade, your buds will be significantly less potent than they should be.
Sativa-dominant strains can require a lot of patience, usually taking 3 to 4 months to complete flowering. Indica dominant and hybrid strains are faster. They can be ready for harvest with 2-3 months of flowering. A photoperiodic cannabis cultivation outdoors involves a considerable investment of the grower's time.
It could take 6 to 9 months from the day the seeds germinated before harvesting a stash. In general, the most sativa strains should be harvested with a mixture of clear and milky resin heads to ensure an uplifting euphoric high. Some Sativas are in the range of 60 to 75 days to bloom and some are even longer up to 80 to 120 days of flowering for some strains. However, if you want to experience a sativa-like effect with your indica strains, you can start harvesting around day 55.If you extend the flowering period, you run the risk of diminishing both the flavor and the stimulant effect typical of sativas.
For example, I tend to harvest Sativas with fewer amber trichomes than Indicas, since I want a more stimulating and energetic effect. Sativa plants grown outdoors will bloom later than indica plants because they will depend on the growing season. These are the guidelines for Indica, Sativa and Hybrid strains, but the guidelines for individual strains are even more precise. As for the maturity level, which, again, greatly influences the effect, just consider whether your autoflowering plant is an indica or a sativa and follow the tips above.
When 70% of these trichome heads are milky and 30% are amber, it's the perfect time to harvest mainly Sativa hybrids and long-flowering strains (such as Haze). The only difference here is in the structure of the flowers, which have a more swollen calyx and are a little more open, somewhere between an indica and a sativa. Determining the right time to harvest your marijuana plants depends largely on the type of strain you're growing, whether it's indica or sativa. The effect is clear and psychedelic, as in the case of Super Silver, Royale Haze, Dinamex, Moby Dick and Santa Sativa.
On the other hand, Sativa plants grow much taller and have very thin leaves, with flexible stems and a much longer flowering period.
