Chemotype
Type I
THC-dominant
Terpene profile most dominant first
Chemotype — the cannabinoid and terpene profile — is the signal that stays true to a cultivar’s genetics, which is why scientists classify cannabis by chemical profile (a “chemovar”) rather than by name (Hazekamp & Fischedick 2012). The dominant terpenes below are aggregated from community and lab reporting; aroma and effect associations are preliminary and not medical claims. Lab-verified COA profiles roll out as Areto’s data comes online.
Indica / Sativa — retail shopping guide
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 Emerald Jack
We crossed two of the strongest, most beloved and desired sativa-dominant hybrids in the world to create this symphony of flavors. Emerald Jack grows tall quickly, doubling in size after moving into the fl owering cycle, so don’t be afraid to flip it early indoors. Be sure to stake these early and often or employ a trellis to support the massive terminal bud growth.
Healthy doses of nitrogen, calcium and magnesium will be essential in getting the plant to its full potential. You will be rewarded for your labor by a thick harvest of resin-encrusted colas. The tropical fruit salad of the Jack Herer collides with the intense sour of the Emerald OG to create a tangy, unique taste that lingers on the palate. Emerald Jack produces an uplifting, energetic high, stimulating creative and euphoric thoughts. Genetics: Jack Herer x Emerald OG
