    Critical Mass Fast retains all the qualities that made its parent strain famous—huge buds, intense resin production and sweet, pleasant flavours—while cutting the flowering period nearly in half. Its 22% THC level ensures a potent body-heavy effect paired with a soothing mental calm. Buds develop quickly, densely and with impressive trichome coverage, making this version ideal for those who want high-quality harvests in record time.
  
  
Growing Information:

    This fast version thrives in almost any growing setup and is especially beneficial for regions with short outdoor seasons. Indoors, plants remain compact and manageable at 70–90 cm while still producing exceptional yields. Outdoors, they stretch to 1.8–2.2 metres and finish early—harvesting by early September—before autumn humidity becomes an issue. With a flowering period of only 40–45 days, growers can enjoy exceptionally quick results without sacrificing density or resin content.
  
  
Strain Flavour and Aromas:

    Critical Mass Fast features a sweet, sugary aroma accompanied by a smooth, rich palate. The flavour profile leans strongly toward sweetness with gentle earthy undertones, making it a pleasant and easy strain to enjoy. Its terpene expression enhances both aroma and effect, contributing to its soothing and relaxing nature.
  
  
Strain Lineage:

    Critical Mass Fast derives directly from Critical Mass through selective breeding to shorten flowering times. The original Afghan × Skunk #1 traits remain strongly present, ensuring abundant yields, dense buds and a sweet, resin-heavy character—now with a dramatically faster finishing cycle.
