Critical Fast Seeds
Price range: $52.00 through $255.00
Critical Fast Seeds are a fast-flowering photoperiod expression of the Critical cultivar family, selected to retain the compact structure, heavy branching, dense flower formation, and sweet-skunky aroma associated with Critical while shortening the bloom period. Fast versions are produced through different breeding routes, so the exact additional parentage should not be treated as universal.
- Lineage: Critical-family genetics selected or crossed for faster photoperiod flowering; exact fast-line parentage varies
- Growth type: Indica-leaning fast photoperiod hybrid
- Plant structure: Short to medium, sturdy, with short internodes and strong lateral branching
- Stretch: Low to moderate
- Indoor flowering: Typically about 7–8 weeks (roughly 49–56 days)
- Outdoor harvest: Typically late September in the Northern Hemisphere, with some phenotypes extending into early October
- Flower structure: Dense, compact clusters with substantial weight on the main stem and upper branches
- Resin production: Moderate to high
- Colour: Bright to medium green with orange-to-amber pistils
- Aroma: Sweet fruit, skunk, earth, spice, and light citrus
- Best suited for: Growers wanting a compact photoperiod plant with a materially earlier finish than standard Critical selections
Critical Fast generally develops a balanced, sturdy canopy that is easy to manage indoors. Topping or low-stress training can help distribute growth across several productive branches, while the relatively short internodes keep the plant compact compared with more sativa-leaning cultivars.
Indoors, a practical target is approximately 49–56 days after the switch to 12/12. Flowers usually stack densely during the second half of bloom and can place considerable weight on the upper branches. Good airflow is useful as the flower clusters tighten.
Outdoors, the fast trait is most valuable where autumn weather becomes unreliable. A practical Northern Hemisphere target is late September, with slower phenotypes capable of extending into the first part of October. Exact timing depends on latitude, seasonal conditions, and the particular fast line.
The aromatic profile commonly combines sweet fruit and skunk with earthy, spicy, and lightly citrus notes. Critical Fast Seeds are best suited to growers looking for compact structure, dense flowers, and a seven-to-eight-week photoperiod bloom.
