Genetics & Origin of K.C. 42
K.C. 42 is one of the numbered creations from KC Brains. According to the breeder, a New Zealand line – "New Zealand's best" from the year 1999, elsewhere described as a landrace – was crossed with a K.C. 639 male for it. The outcome is a stable, predominantly Sativa-influenced hybrid; KC Brains does not state exact percentages of Sativa and Indica. According to the manufacturer, the THC content is 20 to 22%, and the CBD content is low. The strain is photoperiod, and this item contains regular seeds: the seeds grow into male and female plants, which makes selection and your own crosses possible. The breeder highlights the resilience and the tolerance of moisture. If you do not want to select, you will also find the strain as K.C. 42 in the feminised version.
Who Is K.C. 42 For?
K.C. 42 is a large, late-ripening Sativa with a focus on open ground. It suits:
- Experienced outdoor growers with room for plants of 200 to 250 cm
- Gardeners in mild locations where harvesting is possible into November
- Selectors who choose mother and father plants from regular seeds
- Yield-focused growers aiming for up to 1,300 g per plant
- Consumers looking for a clear, stimulating strain for the daytime
It is not intended for a first grow, and in regions with early frost the harvest from the end of October becomes a risk. You can find more strains for open ground under regular outdoor seeds.
Growing K.C. 42: Indoor & Outdoor
Indoor Growing
KC Brains gives two different figures for the flowering time: the data sheet states 9 to 12 weeks indoors, while elsewhere the manufacturer speaks of 6 to 9 weeks. To be on the safe side, plan with the longer span and judge ripeness by the trichomes. Indoors the plants grow up to 170 cm tall and, according to the breeder, have a high light requirement – a tall room and strong lighting are a prerequisite. The manufacturer does not state a yield per area in g/m². During flowering the strain smells strongly, and KC Brains recommends a filter. As the seeds are regular, you determine the sex in pre-flowering and remove male plants if you do not want to produce seeds. More on this in the Growpedia.
Outdoor Growing
K.C. 42 shows its strength outdoors: there it grows 200 to 250 cm tall and, according to the manufacturer, produces up to 1,300 g per plant. Outside, flowering takes 9 to 12 or 9 to 14 weeks, depending on which figure you go by; harvest is at the end of October, according to the data sheet in some cases as late as mid-November. That requires a long, mild autumn. KC Brains describes the strain as tolerant of moisture and recommends mild to temperate regions. Only grow where it is legal to do so.
Effect, Aroma & Flavour of K.C. 42
KC Brains describes the scent of K.C. 42 as fresh citrus with a light hash undertone; for the flavour, the manufacturer cites fruity, tart notes with a spicy, Haze-like finish. The manufacturer does not state a lab terpene profile. According to its information, the effect is clear and cerebral: motivating, stimulating and energetic, with a creative note – a strain for the daytime and for sociable hours. With 20 to 22% THC and a low CBD content, K.C. 42 is strong. Because plants from regular seeds vary more than cuttings from one mother, aroma and effect can differ somewhat from plant to plant. How intense the effect is also depends on harvest time, dose and personal tolerance.
