G13 Genius — Brothers Grimm Seeds

Seb's take

Seb Silverback

Sour lime and lemon on the nose, from an Airborne G13/HP cross paired with the straightforwardly named Genius. The high is psychedelic yet grounding, calming and relaxed rather than scattered. Consistent, resinous, connoisseur-grade harvests — a plant that lives up to its own name, which takes some doing.

Growing G13 Genius: what to expect

Feminized photoperiod stock. You control when she flowers, which is a responsibility as much as a convenience; the light schedule guide keeps you on the right side of it.

She takes a conventional 10 weeks to flower. Conventional is underrated; so is knowing what week you're in.

Expect 450-600 g/m² — a working grower's yield, reliable rather than theatrical. The harvest guide will see it in safely.

The aroma is citrus-forward: zest first, everything else in its wake.

Grower reports give her a relaxed lean: unhurried company for an unhurried evening.
