The shortest version: Fast Buds's take on indica genetics, 19-24% THC, 9-10 weeks from seed flowering, easy grow.

Fast Buds lists this at $37.91 — above the median of $31.46 across 15 listings. Pack options: 3-seed at $37.91, 5-seed at $63.18, plus larger sizes.

Lineage: Fast Buds' medical-focused auto, bred specifically to push CBD output while keeping THC in a range that clears legal thresholds in many jurisdictions. What makes this one unusual is the ratio — 20:1 CBD to THC — which puts it in a category most therapeutic growers actively search for but rarely find paired with a yield worth the effort. Indoors, expect 400–550 g/m² in roughly 9–10 weeks from seed, with a sweet, earthy profile that stays clean through dry and cure. Difficulty is low, so first-time cultivators won't need to overthink it, and it performs equally well in outdoor beds or a tent setup.

The THC sits in the 19–24% range on paper, but the dominant CBD presence effectively offsets that psychoactivity for most users — which is exactly the point. Best suited for growers supplying personal therapeutic use or anyone building a CBD-forward garden without sacrificing actual harvest numbers.

Growing CBD Auto 20:1

Indoor Growing: Expect a flowering time of 9-10 weeks from seed with yields of 400-550 g/m². Plants typically reach 70-90 cm 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 40-50% 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.

A smooth, candy-like sweetness defines the flavor, with subtle complexity on the exhale. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.
