Growing Information:

    Growers of all skill levels will appreciate this strain’s adaptability and resilience. Indoors, plants stay compact at 80–90 cm and can easily fit into small or medium grow spaces. Outdoors, they reach up to 2.2 metres and produce abundant yields before the autumn rains, thanks to their mid-September finishing time. The fast flowering period of only 50–55 days allows for multiple indoor harvests per year and makes outdoor growing viable in climates with short summers.
  
  
Strain Flavour and Aromas:

    Critical Lemon Fast offers a vibrant citrus bouquet characterised by lemon zest and grapefruit notes. The flavour is bright, refreshing and tangy, often accompanied by a light sweetness on the exhale. The terpene profile suggests strong limonene dominance, contributing to its energising aromatic character.
  
  
Strain Lineage:

    This fast version is derived from Critical Lemon combined with early-finishing genetics to reduce flowering time while maintaining potency and flavour. The result is a vigorous, aromatic hybrid that retains the heavy production and citrus richness of its parent but with a significantly quicker life cycle.
