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 Sir Jack
Definitely one of the clones we like to work with and grow the most, selected around the year 2000, now presented in its "S1" version, crossed with itself so that you can enjoy this selection as much as we do; originally from Sensi Seeds Jack Herer. Sir Jack is a robust plant, which helps keep the weight of its large flowers. With an elevated level of resin, it is highly recommended for performing extractions, producing a super high quality "Ice-O-Lator". With Sir Jack we recommend monitoring the humidity of the room, since the density of its flowers, with a high relative humidity, can potentially cause Botrytis to appear. But if there is something worth highlighting about Sir Jack is its taste and effect, which has granted it multiple awards throughout its career, with a clearly marked incense and lemon flavour, which lingers on the palate, being a difficult taste to forget, like its effect, strongly brainy, which leads to a more Indica-type body feeling, without being disabling. This strain is not recommended for novice smokers. Yield m²: 550-600 g
Percentage Indica/Sativa: 30%-70% Outdoor harvest: October
