Indica / Sativa — retail shopping guide

Indica 30%Sativa 70%

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 Chernobyl S1

Created from pre-fire F1 seed stock, Chernobyl S1 preserves the legendary legacy of Subcool’s original masterpiece. Unlike “Slymer” phenos, the true F1 Chernobyl grows massive, vigorous, sativa-leaning plants — especially suited for outdoor cultivation. It produces a dense sparkle of trichomes across the buds and sugar leaves, making it an old-school favorite for hash makers. Classic, loud, and unmistakably nostalgic — this is the real Chernobyl experience. Lineage: Bloodwreck x Jack the Ripper (F1) Reversed. Flowering Time: 8-10+ Weeks Indica/Sativa: Sativa Dominant Height: 3’–5’ Indoors / 7’–10’ Outdoors Phenotypes: Longer-flowering phenotypes are heavy sativas bursting with sharp lime flavor. Faster-finishing types are funky, earthy, and seriously DANK. Our keeper finishes in 8 weeks, has FAT buds, and we can barely keep it in the head stash! High Type: Clear-headed and energetic, with a light, relaxing body effect. Aroma/Terps: Bright lime, pine, and earthy funk. Yield: Heavy producer indoors and outdoors. Grow Notes: Vigorous, sturdy plant with strong lateral branching. Outdoors, expect towering 7’–10’ giants in 15–30 gallon pots. Watch for early bud development — fast-finishi
