About G13

G13 is an indica-leaning strain. You may also see it sold as G-13, G Thirteen. People who try it most often describe feeling sleepy, euphoric and hungry.

THC and potency

Public lab results give a good picture of its strength: 25 flower samples tested between 2022 and 2024 came in at a median of 16% total THC (the middle half ranged from 14.5% to 17.6%). That is in line with most flower on Canadian shelves. Potency varies by grower and batch, so always check the label.

Aroma, flavour and terpenes

Its reported terpene profile is led by myrcene, with limonene and caryophyllene. Myrcene is known for earthy, musky notes with a ripe-fruit edge, while limonene adds bright citrus-peel freshness. Consumers most often describe the flavour as pine, earthy and woody.
