Type and genetics

The cannabis seeds + Speed Auto by Sweet Seeds are the result of crossing Critical Mass Auto x Speed Devil #2 Auto, in which Critical brings the intense flavor and aroma so characteristic of this strain, and Speed Devil gives it a faster flowering stage.


+Speed Auto of Sweet Seeds is known for its vigorous growth, fast flowering and contained height. Due to its fast growth and short life cycle, it is recommended to water little by little during the first weeks of life in order not to drown its small roots and to increase its growth.
