Top 7 best Auto flowering Sativas

The best autoflowering Sativas are some of the most demanded varieties by seed collectors around the world. They are genetics with special characteristics, as will be seen below. Today’s article will present some of the best specimens of this seed lineage.

Sativa autoflowering began to grow thanks to pioneer breeders such as Neville Schoenmakers or Arjan Roskam, who began to bring varieties from areas near the equator, such as seeds from the Haze family, which were combined with Ruderails varieties so that they were not photodependent.

Although at the beginning the first experiments carried out in this field did not give the best results in terms of performance, active cannabinoids, resistance or short life cycle, with the passage of time these errors have been corrected.

Today it is possible to enjoy the best autoflowering Sativas in collector’s seed format. These varieties have been duly stabilized to maintain the main Sativa characteristics of their parents while maintaining a short life cycle and the ability to start flowering without the need to perceive a change in photoperiod.
