BlackJack — Nirvana Seeds

Seb's take

Seb Silverback

BlackJack, Nirvana's cross of Black Domina and Jock Horror, is sweet and citrusy up front with an earthy pine finish, and does not travel discreetly, whatever the excuse. The trichome-heavy smoke helps loosen the shyest of tongues, running happy, creative, and relaxed with just enough uplift to stay social. Wonderful for a phone call; less so for a lift.

Growing BlackJack: 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.

A 11-week flowering run — the scenic route. Worth it, generally, but plan your season around her rather than the other way about. See the flowering stage.

Expect 400 – 500 g/m² — a working grower's yield, reliable rather than theatrical. The harvest guide will see it in safely.

Earthy on the nose — the old-school profile, done properly.

Effects report as chiefly uplifting — she raises the tone of a room rather than lowering the lights.
