Manufacturer Information
Genetics & Origin of Spontanica
KC Brains describes Spontanica as a stable cross between a “secret project no. 1” and a K.C. 33; the breeder reveals nothing more about the first parent. The genetics are dominated by Indica genes, and the manufacturer does not state exact shares. In growth, this shows in bushy plants with dark green leaves on a thin but sturdy stem. What is unusual is the size potential, which KC Brains highlights as a distinguishing feature: outdoors, individual specimens are said to reach up to 4.5 m. The breeder puts the THC content at 18 to 20% and does not state a CBD value. According to the manufacturer, the strain is considered mould-resistant and is particularly easy to clone. The seeds are feminised and photoperiod. Mind Bender, which you will find in our range, also comes from KC Brains.
Who Is Spontanica For?
Spontanica is first and foremost an open-ground strain. It suits:
- Outdoor gardeners with plenty of room upwards and to the sides
- Growers with a greenhouse who want to raise large plants
- Gardeners in damper locations who set store by mould resistance
- Growers who would like to take cuttings and keep a mother plant
- Lovers of sweet, aromatic Indica flowers with 18 to 20% THC
It is less suitable for low grow tents and for small gardens with little room upwards – up to 4.5 m are possible outdoors according to the manufacturer. More Indica-dominant strains can be found under Indica strains.
Growing Spontanica: Indoor & Outdoor
Indoor Growing
Although Spontanica was bred for outdoors, KC Brains credits it with excellent qualities for greenhouse and grow room. Indoors it retains its Indica character and, according to the manufacturer, stays at around 150 cm – still sizeable for many tents, which is why a short vegetative phase and tying down are advisable. Flowering takes 8 to 10 weeks; the data list says around 9 weeks. The breeder does not state an indoor yield in g/m². The flowers become large, compact and sticky; KC Brains recommends tying up the branches if necessary because of the weight. You will find the basics on training and climate in the Growpedia.
Outdoor Growing
Outdoors, the strain plays to its strength. According to the manufacturer, individual plants can grow up to 4.5 m tall, and the yield reaches up to 900 g per plant. Harvest is from late September to mid-October; in the data list, KC Brains states mid-October. The mould resistance helps in autumn, but the heavy, highly aromatic flower clusters should be supported or tied up. Plan for a sunny spot with plenty of distance from the neighbouring plants. Only grow where it is legal to do so.
Effect, Aroma & Flavour of Spontanica
KC Brains remains brief on aroma and effect. The breeder describes the flowers as highly aromatic, large, shiny and sticky; as early as towards the end of flowering they give off a soft, sweet flavour that is retained to the very end. It does not list individual aroma notes or terpenes: the manufacturer does not give a lab terpene profile. KC Brains sums up the effect in one sentence – very gentle, but strong. Whether it is felt more in the body or more in the head, how quickly it sets in and how long it lasts is left open by the strain description; we deliberately add nothing on this. The THC content is said to be between 18 and 20%. How intensely you experience the strain depends on dose and personal tolerance.
