Indica / Sativa — retail shopping guide

Indica 70%Sativa 30%

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 Amsterdam

Skunk is the original hybrid - the first ever stable crossing of an Indica and a Sativa. Today skunk is often used to refer to any powerful marijuana, but only the original skunk can live up to its reputation: very smelly, and very, very strong. John Sinclair has been a long lover of potent ganja, and this is his own tribute to the widely loved Skunk: a fast growing, high yielding plant with exceptionally strong effects. Named after the smelliest inhabitant of the animal kingdom, the naming of this plant is not coincidental. You will recognize a skunk first and foremost by the pungent odour kicking your nostrils with solid force. When up in smoke, the skunk hits fast and heavy – this is a smoke for those who can take a punch! With both Sativa and Indica in her genes, the skunk gives a gorgeous combination of high and stone, one of the most sought-after effects in the entire world of cannabis! The Skunk is probably one of the most satisfying plants to grow. As the Skunk has been around for decades, its genetics have had time to stabilize properly, which gives John Sinclair Skunk a consistent structure and steady bud formation, and she delivers every single time.
