Automatic cannabis seeds
The auto-flowering gene occurs only in Cannabis Ruderalis species. They usually come from Canada and Russia and produce very low levels of THC.
Characteristics of automatic marijuana seeds
In recent years, the automatic flowering trait has been transmitted to THC, photoperiod strains through several breeding steps, thus achieving automatic flowering plants with high psychoactivity. At the same time, the yields of the original Ruderalis varieties have been increased notably, since they're normally very low.
Autoflowering seeds do not depend on photoperiod - which is to say, do not respond to the day / night light cycle - but will start flowering three or four weeks after seed germination.
Growing autoflowering seeds
Autoflowering seeds can be grown at any time of the year. However, in order to optimize their performance, we recommend planting them from March to late August. Notice that it can take from 60 to 70 days from seed germination to harvest, so it would be possible to make 3 to 4 crops per year, mainly depending on the latitude and evironmental conditions of our growing spot.
Indoors, we recommend a photoperiod of 20h of light and 4 hours of complete darkness a day for the entire cycle. Since autoflowering seeds can be harvested after 60 or 70 days from germination, a 10L pot is enough for the entire cycle. There's no need to grow in larger containers since we will get virtually the same harvest, and we should always plant our Auto seeds into the definitive container (they hate transplants).
Autoflowering strains can not be cloned because they automatically start blooming even before developing a nice rootball or receiving a minimum growth period.
