Indica / Sativa — retail shopping guide

Indica 50%Sativa 50%

Indica, sativa and hybrid are a retail shopping convention — not a reliable guide to genetics or effects. When researchers analysed 89,923 commercial samples across six states, these labels did not predict a plant’s terpene or cannabinoid profile, and a genome-wide study found sativa- and indica-labelled plants to be genetically indistinct (PLOS ONE 2022; Nature Plants 2021). The labels are so fluid that AK-47, a hybrid, won “Best Sativa” at the 1999 Cannabis Cup and “Best Indica” four years later. For an accurate, genetics-true picture, see the chemotype above.

About Runtz Fast

Runtz (fast) feminized seeds deliver the full sensory profile of the original Runtz in a shortened flowering window, finishing approximately one week ahead of the standard 8–9 week schedule. This strain sits just on the indica-dominant side of balanced hybrid, producing dense, resinous buds with the striking purple and lime-green colouration the variety is known for. Consistent genetics across the pack mean predictable structure, aroma, and potency from seed to harvest. Genetics & Lineage Runtz is a cross of Gelato and Zkittlez, two strains that between them carry some of the most sought-after terpene and resin profiles of the past decade. Gelato contributes the creamy, dessert-leaning depth and the tendency toward compact, frost-heavy flower structure. Zkittlez brings the tropical fruit intensity, the colour expression, and a relaxing physical quality that anchors the high. The fast-flowering trait has been bred in without sacrificing these characteristics — the result is a feminized strain that retains the full genetic expression of the original while reducing the total grow cycle by roughly seven days. Aroma, Flavour & Effects The terpene profile is led by Limonene and Linalool.
