Mendocino Farms runs this as a sativa feminized line — 25% THC lab range, citrus/earthy-dominant terps, 10-11 weeks from flip.

Lineage: Mendo Breath × Headband × Trainwreck, all three sourced from NorCal's Emerald Triangle region, make Blob OG a sativa with a clear origin story rather than a mystery cross. At 25% THC and a 10–11 week flower period, it sits on the longer end for a feminized sativa, so growers running tight seasonal windows in Ontario or Quebec should plan accordingly. The flavor profile leans citrus and pine with a grounding earthy base—nothing shocking, but the terpene combination holds well through cure. Indoors, expect around 450 g/m²; outdoor runs in BC or Alberta's southern valleys can push that further with a late-September harvest target. Plants stay manageable in height, which helps under grow-tent ceilings.

Intermediate growers comfortable with moderate feeding schedules and some canopy management will get the most out of this one—beginners may want a few runs under their belt first.

Genetics & Lineage

Blob OG traces its genetics to Proprietary cross (Mendocino Farms). This sativa-dominant feminized seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by Mendocino Farms, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and euphoric effects, making this strain ideal for evening use and unwinding after a long day. The body-centered stone builds gradually, easing tension and promoting deep physical relaxation. With THC levels reaching 25%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Blob OG delivers THC levels of 25%, placing it in the high-potency category alongside powerhouses like Gorilla Glue and Girl Scout Cookies. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within minutes, starting as a cerebral buzz that gradually expands.

Growing Blob OG

Blob OG is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 10-11 weeks with yields of 450g/m2. Plants typically reach 100-160cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. Maintain temperatures between 68-80°F with relative humidity around 45-55% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with dense flower formations.

Flavor, Aroma & Terpene Profile

Blob OG features a citrus, earthy, pine terpene profile that develops complexity throughout the flowering cycle. Bright lemon and orange zest punch through on the inhale, with a tangy, refreshing finish. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, Blob OG is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.
