Genetics & Origin of K.C. 33
K.C. 33 is a stable Sativa-Indica hybrid from the breeder KC Brains whose ancestors come from Thailand and Brazil. According to the manufacturer, it was developed specifically for growing outdoors; its stable genes, however, also make it usable indoors. In its growth it behaves like a typical Sativa: large, slender plants with narrow, light green leaves and thick flowers. According to the breeder, it has inherited some traits of traditional landraces from its Thai and Brazilian ancestors, including a high resistance to fungi and diseases. KC Brains does not state exact Indica and Sativa proportions. On the THC content, the wording is cautious: the flowers are said to reach 20 to 22%. The seeds are feminised and photoperiod. You can find more strains with a landrace heritage under Classics and Landraces.
Who Is K.C. 33 For?
K.C. 33 is first and foremost an outdoor strain for large gardens. It suits:
- Outdoor growers with plenty of space for plants 250 to 375 cm tall
- Gardeners looking for a strain that, according to the manufacturer, is resistant to fungi
- Growers who want to harvest a lot outdoors – the manufacturer states around 900 g per plant
- Sativa lovers who like slender plants with narrow leaves
- Consumers who appreciate citrus aromas and a clear, energetic effect
It is less suitable for anyone who needs to rely on a fixed flowering time – the manufacturer's figures contradict each other here – and for small gardens or balconies. You can find more Sativa-leaning strains under Sativa strains.
Growing K.C. 33: Indoor & Outdoor
Indoor Growing
Although K.C. 33 was bred for outdoors, according to KC Brains it can also be kept in a grow room: there it stays under control and grows no taller than about 100 cm. The manufacturer points out that it needs a little longer to grow and ripen and demands more light. On flowering time, its figures diverge widely – the fact sheet states about 8 weeks, elsewhere it is 10 to 16 weeks. So do not rely on the calendar, but judge ripeness by the trichomes. KC Brains does not state a yield in g/m². According to the manufacturer, the strain is tolerant when it comes to watering. You will find the basics on indoor growing in the Growpedia.
Outdoor Growing
Outdoors, K.C. 33 shows what it was bred for. KC Brains states heights of 250 to 375 cm and an average yield of around 900 g per plant. According to the manufacturer, harvest can begin in late September and extends into October; the fact sheet states mid-October. The manufacturer describes the strain as very resistant to fungi and diseases. With this growth height, you need plenty of spacing, a spot in full sun and sturdy supports. Only grow where it is legal to do so.
Effect, Aroma & Flavour of K.C. 33
During flowering, according to KC Brains, K.C. 33 gives off a scent of fresh citrus fruit and sweet spices that becomes more intense with the first flowers; the breeder calls the ripe flowers aromatic. It does not describe the flavour in more detail. The manufacturer does not give a lab terpene profile. There are only a few indications on the effect: the manufacturer speaks of a clear, energetic effect. On the THC content, KC Brains is cautious in its wording – "it is said" that the flowers reach 20 to 22%; this is not a verified measured value. Because the data is thin, we deliberately do not add any further information. How strongly the strain acts depends on dose and personal tolerance.
