Sour Stomper Auto by Mephisto Genetics
Sweet red grape, sour tension and raw funk give Sour Stomper Auto a sharper identity than a generic balanced automatic. GrapeStomper OG brings the darker fruit line, while Sour Crack F5 adds the compact automatic timing and the sour edge behind the profile.
Mephisto Genetics lists the variety as an F7 Feminised Automatic from GrapeStomper OG [Gage Green Genetics] x Sour Crack F5. The official full cycle is 65-75 days from sprout, with plants usually finishing around 60-100 cm. For a separate shop flowering field, the pure flowering phase can be handled as approx. 6-8 weeks.
The plant sits in the medium range and has enough frame to carry its output without needing to be treated like a tall open auto. Early leaf tucking, light Low Stress Training and moderate defoliation can help when the middle begins to close or lower sites need more light, but late heavy shaping is not the point of this line.
Mephisto gives the yield range as 120-150 g per plant. No verified indoor yield per square metre is provided by the breeder, so the per-plant figure remains the clean data point. High growth odour is part of the official profile and should be planned for, especially in tighter multi-plant layouts.
The aroma direction combines sweet red grape with pine-lemon undertones, sour notes, spice and a raw, slightly meaty funk edge. That keeps Sour Stomper Auto denser and more angular than a simple grape automatic. It stands as a medium Mephisto Original with a clear grape-sour signature, strong per-plant output and enough profile definition to sit apart from softer fruit-led lines.
