AK

AK from Barney’s Farm Seeds keeps the old Amsterdam coffeeshop name alive in a modern, high-strength form. These are feminised seeds of a 70% sativa and 30% indica variety made from Mexican x Colombian x Thai x Afghan genetics, with THC listed at 26%.

The appeal is pretty easy to understand. AK has the big, pungent character people expect from the line, but the effect is described as more mellow and uplifting than the name might suggest. It mixes euphoric, cerebral effects with a soothing body feel, so the overall impression is bright and relaxing rather than flat or sleepy.

The aroma is bold and direct. Pungent, skunky notes come through first, with fresh citrus adding lift and earthy depth underneath. On the taste side, Barney’s Farm describes a citrus lead, followed by spicy heat and a grounded earthy finish. It is a familiar AK profile rather than a modern dessert-style flavour.

AK has a long-standing reputation as an Amsterdam classic, and this version keeps the wide four-way background that helped make the strain so recognisable. The Colombian, Mexican, Thai and Afghan blend gives it a sativa-dominant frame, while still producing compact, dense colas with a heavy, resinous look.

Indoors, plants reach around 100–140 cm and can produce up to 500 g/m². Flowering is listed at 60–70 days, or roughly 8–9 weeks, which is fairly quick for something with this much sativa in the mix. Expect a tall, robust structure with long, packed flowers and plenty of frost.

Outdoors, AK can reach 120–160 cm and produce up to 650 g per plant, with harvest around the second to third week of October. Barney’s Farm notes good vigour and adaptability across various climates, making it a sensible pick for growers who want proven genetics, strong resin production and a classic pungent citrus-earth profile.
