Fast flowering strains

Cannabis cultivation involves several stages. Seed germination is followed by the growth and flowering of the plants, which are harvested later on, when they're ripe.

The bloom phase is the most important stage of your crop. It ends when we finally harvest our plants.

When does the flowering period start?

The bloom period begins with the appearance of the first flowers, about 10-15 days after switching the photoperiod to 12 hours of continuous light followed by 12 hours of complete darkness. Autoflowering strains do not depend on photoperiod to develop flowers, for they automatically start flowering 2 or 3 weeks after seed germination.

How long does the flowering stage take?

Cannabis plants need more or less days to ripe depending on the grown strain. Some varieties bloom very fast - taking less than 2 months to ripe - while others may extend their bloom for more than 3 months.

Indoors, a quick flowering allows us to perform several harvests per year. Outdoors, faster strains avoid the risk of rains and molds in October and November.

Here we list the fastest flowering strains on our catalog, with a theoretical bloom period of 8 weeks.
