Manufacturer Information
Genetics & Origin of Runtz S1
Runtz is hard to get hold of as a cutting and at the same time in enormous demand – this is how Elev8 Seeds describes the starting point. For Runtz S1, the breeder crossed an original Runtz, distributed only as a clone, with itself: Runtz × Runtz, original lineage Gelato × Zkittlez. S1 denotes the first generation of such a selfing. According to Elev8 Seeds, some phenotypes correspond exactly to the clone, while others are very similar to it but lean towards one of the two parents. The manufacturer lists the strain as a hybrid without an Indica-Sativa ratio; it does not state THC and CBD values. The seeds are feminised and photoperiod. For comparison, you will find Runtz by Barney's Farm in our range and, with Gelato by Nirvana, a strain from one of the two original lines.
Who Is Runtz S1 For?
Runtz S1 is the seed version of a coveted cutting. It suits:
- Runtz fans who have no access to the original clone
- Selectors looking for the one closest to the clone among several phenotypes
- Indoor growers planning for 8 to 9 weeks of flowering
- Outdoor gardeners with room for large plants and a harvest in October
- Lovers of fruity-sweet aromas
If you expect completely uniform plants, you are less well served by this strain, because according to the breeder the phenotypes turn out differently. You can find more strains with an extra under Bonus Seeds.
Growing Runtz S1: Indoor & Outdoor
Indoor Growing
Elev8 Seeds gives the flowering time as 8 to 9 weeks; it begins after the switch to 12/12. The breeder simply calls the yield “good”, and 450 to 550 g/m² are given as a guide value. The manufacturer does not state a height in centimetres. Because, according to Elev8 Seeds, some phenotypes correspond to the clone and some lean towards one parent, it is worth labelling all plants and taking cuttings before flowering – that way you keep the best plant. Good air movement and a carbon filter are part of the basic equipment during flowering. There is more on climate and cuttings in the Growpedia.
Outdoor Growing
Outdoors, Runtz S1 can grow into a large plant. October is given as the harvest time in the northern hemisphere, and the yield as around 700 g per plant. The breeder itself states no figures for outside. A sunny, sheltered spot helps to bring the flowers through the autumn dry. Only grow where it is legal to do so.
Effect, Aroma & Flavour of Runtz S1
Elev8 Seeds itself gives no information on aroma and effect – the breeder refers solely to the closeness to the original Runtz clone. The strain is described as fruity-sweet, with hints of fruit sweets and tropical fruit. The manufacturer does not state individual terpenes or a lab terpene profile. The effect is considered euphoric and cheerful in the head and later turns into physical relaxation. Elev8 Seeds does not state a THC value; so we do not put a figure on it. Because, according to the breeder, the phenotypes of an S1 turn out differently, the aroma can also differ from plant to plant. How intense the effect is depends on phenotype, dose and individual tolerance.
