Genetics & Origin of K.C. 42
According to KC Brains, K.C. 42 is a stable Sativa/Indica hybrid. For it, the breeder crossed "New Zealands best" from 1999 with a K.C. 639 male from 2001 and describes the result as "very hazy". The strain is Sativa-dominant and behaves like a typical Sativa: tall, slender plants with narrow, light green leaves and yet thick, compact flowers. According to KC Brains, some characteristics of a traditional landrace come from the New Zealand ancestors. The breeder speaks of lower CBD and higher THC levels; the flowers are said to reach 20 to 22% THC. It does not give an Indica/Sativa ratio in figures. The seeds of this item are feminised and photoperiod. From the KC Brains programme, you will also find Brasil x K.C. and Mind Bender in our range.
Who Is K.C. 42 For?
K.C. 42 is a tall-growing Sativa hybrid with a late harvest. It suits:
- Outdoor gardeners with room for plants of 2 to 2.5 m
- Growers in regions with a long, mild autumn
- Yield-focused gardeners – the manufacturer states around 1,300 g per plant
- Lovers of Haze-like Sativas with citrus and hash notes
- Consumers who prefer a clear, energetic effect
The strain is less suitable for short summers and low grow rooms: it only ripens from the end of October and grows up to 170 cm tall even indoors. You can find more strains of this type under feminised Sativa strains.
Growing K.C. 42: Indoor & Outdoor
Indoor Growing
Indoors, according to KC Brains, K.C. 42 stays under control and grows no taller than about 170 cm. The manufacturer gives two different figures for the flowering time: in the summary data it states 9 to 12 weeks, elsewhere 6 to 9 weeks. So, to be on the safe side, plan with the longer range and judge ripeness by the trichomes. The breeder points out that, as a Sativa, the strain needs a little longer to grow and ripen and requires more light. It does not state a yield in g/m². Because of its growth height, it pays to send the plants into flower early and tie down the shoots. You will find the basics on this in the Growpedia.
Outdoor Growing
Outdoors, according to the manufacturer, K.C. 42 reaches 2 to 2.5 m and produces around 1,300 g per plant. Flowering outdoors takes 9 to 14 weeks depending on the figure; harvest begins at the end of October and can extend into November. KC Brains describes the strain as very resistant to fungal infestation and pests. For such a late harvest, however, you need a warm spot with a long, dry autumn as well as sturdy supports. Only grow where it is legal to do so.
Effect, Aroma & Flavour of K.C. 42
KC Brains describes the smell during the flowering phase as a fresh citrus note with light hash, which becomes more intense with the first flowers; the breeder calls the ripe flowers aromatic and sweet. About the cross, it notes "very hazy". The manufacturer does not give a terpene profile. It describes the effect as rather clear-headed and energetic, which it attributes to lower CBD and higher THC levels. KC Brains puts the THC content at 20 to 22%, but phrases this cautiously – the flowers are "said to" reach this value. It does not state a CBD value. We deliberately do not add any estimates of our own. How intense the effect is depends on dose and individual tolerance.
