Indicas tend to have short flowering times, around 7-8 weeks, while sativas usually have long flowering times, usually 8 to 9 weeks, or even longer. Pure Sativa strains can grow to heights of 20 feet because they grow so tall that indoor growers generally stick to indica strains. Sativa normally has a shorter vegetative cycle, but once the plant begins to bloom, it can take 10 to 12 weeks until it is ready for harvest. A pure Sativa strain takes 16 weeks to finish in bloom.
The flowering stage in cannabis plants is usually 8 to 11 weeks, depending on the strain. It is usually divided into weeks or three stages. The flowering period for Indica varieties is usually around 8 weeks, but can take up to 10 weeks. Sativa strains can take 10 to 12 weeks.
Typically, hybrid strains will take 6 to 10 weeks to fully develop. Cannabis sativa is well known for its production of psychoactive chemicals and medications, but it also has enormous potential to be a multipurpose crop. Grown for biofuels, building materials and textiles, cannabis has a high carbon sequestration rate and is sure to be a key player in future sustainable agriculture. Different cannabis applications are directly or indirectly related to flowering and require different flowering time phenotypes.
As a short-day annual plant, cannabis usually blooms in autumn, when days are shortened after a period of initial vegetative growth. However, differences in latitude, temperature and other environmental factors require the development of new cannabis cultivars adapted to local climatic conditions. As such, a comprehensive understanding of the physiological and genetic basis of flowering time is crucial to integrating cannabis into modern agriculture, benefiting global sustainability efforts. Hybrids grow rapidly during the vegetative stage, as do Sativa varieties, but have shorter flowering periods, which is common in most pure indica strains.
Sativa, Indica, and hybrid varieties grow differently and have different degrees of time they take to flower. Cannabis sativa (hereinafter Cannabis) is probably most famous for the valuable secondary compounds, called cannabinoids, which are produced in the trichomes of female flowers and which have a wide range of medical applications. They are also known to have shorter flowering periods than sativas, making them a popular choice for many experienced growers. For most cannabis strains, the flowering period will last between 7 and 9 weeks, although some sativas require even longer for their buds to mature.
If you want to grow Sativa strains, you can prepare for a longer journey, while Indicas will bloom much faster. His research focuses on the characterization of flowering time and plant height in Cannabis sativa, using genetic, transcriptomic and genomic mapping approaches. This simply means that the height of a sativa plant increases during the vegetative and flowering periods. For a hybrid cannabis strain with Sativa dominant traits, flowering periods may be longer and for strains with Indica dominant traits, they may be shorter.
