Description
Born from the storied cross of Afghani and Thai genetics, Northern Lights has earned its place as one of the most respected indicas in cannabis history, and Seedsman's autoflowering feminised interpretation preserves everything that made it a classic. The aroma is grounded and earthy, with that characteristic resinous weight that old-school growers will recognise immediately. Effects lean into the indica side, producing a heavy, relaxing quality that settles in with quiet authority. THC sits in the 16 to 24% range, with minimal CBD.
For cultivation, this is a practical and rewarding choice. As a feminised autoflower, Northern Lights Auto moves from seed to harvest in 10 to 12 weeks, making it well-suited to perpetual indoor cycles or short outdoor windows where timing matters. Indoors, expect 350 to 450 g/m2 from a medium-height plant that fits comfortably in a standard tent without requiring aggressive training. Outdoor plants yield an average of 200 to 450 grams per plant. Its indica structure keeps internodal spacing tight and manageable. For growers who want a reliable, heritage-backed variety with minimal fuss, Northern Lights Auto is a natural first choice.

about this product
Northern Lights Auto brings legendary Afghani x Thai genetics into an effortless autoflowering format, ready for beginner growers who want potent, earthy results without the fuss.
Northern Lights Auto is widely regarded as one of the most beginner-friendly strains available, and Seedsman's feminised autoflowering version leans into that reputation. The feminised format removes the need to identify and remove male plants, while the autoflowering trait means it moves from seed to harvest in just 10 to 12 weeks without any light-schedule management required.
Indoor growers can expect somewhere in the range of 350 to 450 grams per square metre under good conditions, which sits comfortably in the average bracket for an auto. Individual plants can produce between 200 and 450 grams depending on pot size, light intensity, and how well environmental conditions are dialled in.
This is very much an after-dark cultivar. The Afghani-dominant genetics push the experience firmly toward deep physical relaxation with a sleepy, settling quality that makes it better suited to winding down than staying productive. THC runs between 16 and 24%, so the potency is genuine rather than subtle.
The aroma and flavour stay true to the classic Northern Lights profile — earthy, resinous, and grounded, with that old-school hash-adjacent depth that longtime growers associate with authentic Afghani lineage. It's not a complex fruit-forward terpene profile, but for those who appreciate traditional indica character, it delivers exactly what you'd hope for.
