Northern Lights #10 — Herbies Seeds

Seb's take

Seb Silverback

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.

Growing Northern Lights #10: what to expect

Feminized photoperiod seed: every plant a female, and flowering starts when you change the lights — which puts the calendar in your hands. The photoperiod lesson covers using that control well.

She finishes flowering in around 8 weeks — brisk work by any standard. Read up on the flowering stage before she starts, because she won't wait while you do.

A middling 150 cm or so at maturity — tall enough to yield, short enough to manage. Standard tent territory; the light planner sorts the hanging height.

The yield is, in plain terms, heavy — 549 – 641 g/m² when she's looked after. Branches will need support before they need sympathy; see supporting heavy colas.

The listed THC is 33%, which wants no exaggeration from anyone. Among the strongest figures in the catalogue.
