Smuggled into the Netherlands as seed stock in the Seventies and quietly regarded as the best of the Northern Lights line to follow — modesty was never part of the story. At 29–33% THC, approach this 75% indica hybrid as you would a staircase in the dark. Everything home growers wanted then, apparently, still holds.
Where it comes from
The record is candid that fact and fiction blur around the earliest strains, but places the Northern Lights family's origins in the United States in the Seventies, before a batch of seeds was smuggled into the Netherlands and spawned the whole line. Of those, the record reckons #10 the best — modesty, as ever with this family, not part of the story. Herbies Seeds carry a 75% indica cut crossed with an undisclosed hybrid. A smuggler's inheritance, at the top of its class.
Nose & flavour
The tasting notes go unrecorded, so the heritage must speak — and the Northern Lights line runs to the sweet, earthy, resinous end throughout. From a plant this potent, expect a correspondingly concentrated aroma. What the record withholds in specifics, the pedigree fills in well enough.
The high
At 29 to 33% THC, this is a plant to approach as you would a staircase in the dark. The effect leans on the 75% indica share for its weight, and there is a great deal of it — a sipping strain, not a session one. The record calls #10 the best of a very good family, and at these figures it is not one to underestimate. Considerable respect advised.
Growing it
A medium plant, 120 to 150cm, finishing quickly at around 53 days — brisk, given the potency it packs into that window. Yields land at a heavy 549 to 641 g/m². For all its strength, she is a manageable size and a reasonable timeline, which makes the payoff more accessible than the THC figure might imply. A generous, potent grow for someone ready to handle the result.
