Fast flowering and early cannabis strains

There are 392 products tagged as Fast flowering genetics

The tag fast flowering cannabis includes all photo-dependent cannabis strains that complete their maturation in a period of about 8 weeks or less at 12/12 cycle.

Difference between Early and Fast flowering cannabis

Early Version are varieties resulting from crosses between a photo-dependent and an auto-flowering strain. The resulting in a photo-dependent plant, yet with a faster flowering period compared to a 100% photo-dependent plant. That is approximately 2 weeks earlier.

When cannabis flowering start?

Cannabis cultivation involves several stages: germination, growth, pre-flowering, flowering and harvest.

Cannabis flowering begins when the first flowers appear, usually around 10-20 days after the photoperiod change to 12/12, the so-called pre-flowering period. In auto-flowering varieties, flowering does not depend on the photoperiod, so it starts automatically from 2-4 weeks after the seed germination.

Once in photoperiod flowering, the plants perform the last stretch, also known as stretching. The plant can double or even triple its size depending on the genetics.

It is important to mention that some growers and seedbanks begin to count the flowering period after the photoperiod change to 12/12. Others when the pre-flowering ends and appear the first flowers. This is why it can be a small range of about two weeks in some seedbank specifications. It is important to look at the trichomes at harvest time using the seedbank information as a reference.

How long does cannabis flowering last?

Cannabis plants complete flowering, flower maturity, in more or less time depending on the variety. Some cannabis hybrids require about 8 weeks or less at 12/12 photoperiod, while other may need even more than 14 weeks.

In indoor cannabis cultivation, choosing fast flowering strains allows for several harvests per year. Outdoors, the risk of possible pests is minimised, less exposure time, and can be harvested before the October and November rains in the Northern Hemisphere.

Here we present the fast flowering strains offered in our catalogue. They are cannabis seeds with a theoretical period of about 8 weeks or below after the change to 12/12. We include Fast Versions or Early Version, both feminised and regular.
