Sour Crack Auto
The fastest autoflower from Mephisto Genetics. From seed to harvest in just 60-65 days with energizing sativa effects and mouth-watering sour candy flavor.
Sour Crack Auto by Mephisto Genetics is legendary in the autoflower community for being one of the fastest-finishing cannabis strains available anywhere. Created by crossing Green Crack with 24 Carat, this sativa-dominant hybrid delivers a potent, energizing experience in record time.
With a seed-to-harvest time of just 60-65 days, Sour Crack Auto allows Canadian growers to achieve multiple harvests in a single season - something that was previously impossible with traditional photoperiod strains in our northern climate.
Perfect for Canada's Short Growing Season
The ultra-fast lifecycle of Sour Crack Auto makes it uniquely suited for Canadian outdoor growing. Even in regions with shorter summers like the Prairies or Northern Ontario, growers can confidently plant in June and harvest before September frost. Southern growers in Ontario, BC, and the Maritimes can potentially achieve two full outdoor harvests.
The compact size (45-75cm) makes Sour Crack Auto perfect for balcony grows, guerrilla growing, or discreet backyard gardens. Despite its small stature, the dense, resinous buds pack a serious punch with 20-24% THC content.
Mephisto Genetics Quality
Mephisto Genetics is renowned for producing some of the highest-quality autoflowering genetics in the world. Their breeding program focuses on creating stable, potent autos that rival photoperiod strains in quality. Sour Crack Auto exemplifies this commitment to excellence.
Speed Growing Tips
- Plant directly in final container (7-15L) - no time for transplant recovery

How fast can I harvest Sour Crack Auto?

Yes! Due to its 60-65 day lifecycle, you can potentially grow 2-3 cycles outdoors in southern Canada. Start the first batch in late May, second in mid-July, and harvest both before frost. In northern regions, you can reliably get at least one full cycle.
