Description
Born from a cross of the legendary Northern Lights and Green-O-Matic, Greenhouse Seed Co.'s Northern Lights Auto carries the lineage of one of cannabis culture's most enduring indica classics into autoflowering territory. The aroma profile leans into cool mint layered over a familiar skunky earthiness, and the high THC range of 16 to 24% delivers a grounding, deeply relaxing experience that reflects its predominantly indica character.
As a feminised autoflower, this one is straightforward to plan around. Plants reach a medium height, keeping them manageable in a grow tent or a discreet outdoor plot. Indoor growers can expect 350 to 450 g/m2, while outdoor plants in a suitable climate can yield up to 200 g per plant. The 10 to 12 week seed-to-harvest window is a genuine asset, allowing multiple runs in a single season or year-round indoor cycling without the need to manage light schedules. For growers looking to bring a piece of Northern Lights history into their garden without the complexity of photoperiod timing, this is a quietly capable choice.

about this product
Northern Lights Auto brings legendary NL genetics into a fast, fuss-free feminised format — everything you need to grow a classic indica with confidence.
Northern Lights Auto is specifically rated as easy to grow, making it one of the more forgiving options for first-timers. The feminised autoflowering format removes a lot of the guesswork — no need to manage light cycles or sex plants — and the medium height keeps things manageable in a tent or small outdoor space.
The flavour profile is a distinctive combination of cool mint and skunky earthiness that reflects the classic NL character. The high THC range of 16 to 24% produces a grounding, deeply relaxing experience that leans toward the sleepy end of the spectrum, making it best suited to evening use.
From germination to harvest runs 10 to 12 weeks, which is impressively quick for a strain with this much heritage behind it. Indoors you can expect around 350 to 450 grams per square metre, so a 3-seed pack gives you a solid test run to dial in your setup before committing to a larger grow.
Greenhouse Seed Co. crossed the legendary Northern Lights — one of the most celebrated indica strains in cannabis history — with Green-O-Matic to create the autoflowering version. That pairing preserves the relaxing, resinous character NL has always been known for while adding the speed and light-cycle independence of a ruderalis-influenced auto.
