Auto Biodiesel Mass XXL by Advanced Seeds
Auto Biodiesel Mass XXL is a high-production autoflowering cultivar bred by Advanced Seeds. As an evolution of their original Auto Biodiesel Mass, this "XXL" iteration was selectively bred for increased floral density, heightened resin production, and larger overall yields. The genetic lineage is a deliberate cross between Auto Diesel and Auto Critical, effectively merging the pungent aromatic profile of Diesel genetics with the heavy structural traits of the Critical Mass family.
Cultivation of this strain is efficient and highly rewarding, suitable for various skill levels. The plant demonstrates vigorous vegetative growth before transitioning into a heavy flowering phase, completing its entire life cycle in 60 to 70 days. Indoor plants typically reach heights of 80 to 120 centimeters and respond exceptionally well to strong, sustained lighting, with a 20/4 light schedule highly recommended. Outdoor specimens can stretch further, reaching up to 1.6 meters under optimal sunlight.
The yield potential of Auto Biodiesel Mass XXL is a primary defining characteristic. Indoor environments can produce 450 to 500 grams per square meter, while well-maintained outdoor plants can exceed 200 grams per plant. The mature flowers are characterized by a strong, fuel-forward aroma accented by sweet citrus notes. Testing at approximately 17% THC, the harvest provides a potent and aromatic end product backed by consistent agricultural performance.

Growing Auto Biodiesel Mass XXL: what to expect
Because Auto Biodiesel Mass XXL is an autoflower it runs on age, not photoperiod: keep it under 18–20 hours of light from sprout to harvest, start in its final pot, and go easy on training after week 3 — autos never pause to recover. Growers familiar with NYC Diesel or Ruderalis will recognize much of its behavior. Whatever the listing says, the cut in YOUR tent is the ground truth: log feedings, readings, and photos, and let the trends — not the label — drive decisions.
