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.

A cross between our best Green Haze mother (#19) from the Oldtimer's Haze line, and the elite clone of A5 Haze (NL # 5 x Original Haze male A) from Nevil, resulting in a hybrid of almost pure Haze expression with renewed vigour, combining legendary old expressions of green Haze (19, similar to the old green Colombians and Colombian Gold) and brown Haze (A5), both very incense and of excellent quality, which recall some of the best Colombian sativa expressions of the 60s and 70s. The Green Haze #19 mother clearly dominates in this hybrid with her tropical sativa character, both in growth and flowering traits as well as in her psychoactivity. The powerful A5 Haze brings plenty of vigour and yield, and its distinctive classic Colombian Haze aromas which, together with the aged and exotic terpenes of Oldtimer's Haze, come together to create a bouquet, personality and effects that will excite the most purist of Haze hunters. The extremely stable pure Oldtimer's Haze genetics provide uniformity to the highly heterozygous F1 NL Haze, fixing its tropical nature and pure Haze traits so that the influence of Afghan indica
