About Sour Crack
Sour Crack was originally created by Mephisto Genetics and has been carefully preserved by Preservation Seeds.

Sour Crack is a hybrid of 24 Carat and an Auto Green Crack that was still in development at the time. Through careful selection and breeding, it was stabilized into a fully autoflowering variety. Both original photoperiod parents are known for being exceptionally quick and heavily frosted.

The Green Crack side delivers an energetic, rushing high, while the Sour Boggle lineage contributes a deep, Afghan-style narcotic body stone. Together, they create a powerful yet balanced experience that hits hard without feeling one-dimensional.

Sour Crack truly lives up to its name. After extensive testing and refinement, it proved to be the fastest autoflowering variety we have ever grown—and that is saying something considering how many autos we have cultivated over the years. Speed is not its only standout trait; it also produces thick layers of resin and impressive potency to match.

Growing Characteristics
Our goal was to develop a strain ideal for discreet, rapid cycles that could also perform exceptionally well in a commercial-quality autoflowering Sea of Green setup.

When grown in smaller containers, plants remain compact and transition into flowering quickly before powering through to harvest at full speed.

The buds finish dense and solid, with an excellent flower-to-leaf ratio that makes trimming straightforward. They are heavily coated in trichomes and visually striking. Overall, Sour Crack is a beginner-friendly plant. Start it in a light soil mix; once established, it can handle heavier feeding without issue.

Cultivation Details
All performance figures are based on restricted-pot cultivation in organic soil. Plants are started in 1-liter containers and transplanted into 11-liter pots once sex is confirmed.
