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 Silver Jack

This tart and sweet and VERY aromatic strain is a combination of our Jack Herer father plant and a tall and bushy Super Silver Haze Mother plant. You better have a good odor filter because this strain gets real stinky when the SSH and Jack flowers but it is worth it for the sweet flavored smoke it produces. Genetics: (SSH x Jack Herer) F1 Type: F-1; Sativa Hybrid Father: Jack Herer Mom: Super Silver Haze Yield: Medium High: Strong Head high Rank: Intermediate Skill Needed Flowering Time Indoor: 10 weeks Harvesting Outdoor: Early October
