Genetics & Origin of Critical Sour
Female Seeds calls Critical Sour the next generation of its own hybrids. The aim was a very early-ripening outdoor strain. To achieve this, the breeder crossed a mother of Maroc × Grapefruit with an inbred father of Auto NL × Auto NL × Auto Critical, which was meant to speed up flowering. According to the manufacturer, the strain shows traits that clearly come from the mother and from the Auto Critical genes. Critical Sour is Indica-dominant, without percentages being stated, and is listed in the shop as photoperiod. The breeder openly mentions one peculiarity: one in thirty plants can be autoflowering. The strain grows compactly with a strong, flexible stem and carries considerably more flowers than leaves. Female Seeds does not give a THC or CBD value. From the same breeder, the shop also stocks Grape Amnesia.
Who Is Critical Sour For?
Critical Sour is designed for early harvests outdoors. It suits:
- Outdoor gardeners who, depending on the region, would like to harvest as early as September
- Growers looking for a robust plant with an open, well-ventilated flower structure
- Growers for whom a restrained smell is important
- Indoor growers who plan for 8 to 9 weeks of flowering
- Consumers who like a fast-onset, relaxing body high
It is less suitable if top yields are what matter to you – the manufacturer states 180 to 250 g per plant outdoors. You can find more strains of this kind under Indica strains.
Growing Critical Sour: Indoor & Outdoor
Indoor Growing
Indoors, according to Female Seeds, Critical Sour flowers for 8 to 9 weeks and grows 80 to 140 cm tall; the yield is 300 to 450 g/m². The plant grows compactly with a strong, flexible stem, and the wide internodes stretch at the start of flowering. Thick, resinous and dense flowers form, which grow long and rather slender. Because, according to the breeder, one in thirty plants can be autoflowering, you should watch out for individual specimens that start to form flowers before the switch to 12/12. According to the manufacturer, the smell is not particularly strong. Female Seeds gives no training recommendations. You will find the basics on light, climate and feeding in the Growpedia.
Outdoor Growing
Critical Sour was bred for the outdoors: depending on the region, according to the manufacturer, it can be finished as early as the beginning of September. Female Seeds states a height of 100 to 250 cm and 180 to 250 g per plant; at the same time, it is said to stay shorter than the breeder's other outdoor strains. The plant is considered very robust, and the open flower structure lets air circulate, which prevents mould in the final stage. The strain description does not contain exact harvest times for individual regions. Only grow where it is legal to do so.
Effect, Aroma & Flavour of Critical Sour
Female Seeds describes the aroma of Critical Sour as fruity, earthy and spicy. On the inhale the flavour is smooth and delicate and, according to the breeder, reminiscent of the pineapple phenotype of Grapefruit; it attributes the spicy, earthy note to Maroc. Overall, according to the manufacturer, the strain does not smell particularly strong. The manufacturer does not state a lab terpene profile. The effect sets in almost instantly as a body high. The breeder sees in it the strength and couch-lock of NL and Critical, combined with the delicate, subtle high of Maroc and Grapefruit – all in all cheerful, uplifting and relaxing for the whole body. Female Seeds does not state a THC value. How strongly you feel the effect depends on dose and individual tolerance.
