How to grow Black & White Mix

Black & White Mix — Green House Seeds

Seb's take

Seb Silverback

The Black and White Mix pairs Green House's White Rhino and White Widow, two award-winning indica-dominant strains with closely matched flowering times, eight and nine weeks respectively. Both are known for a soaring euphoria and sedative comedown, growing side by side without complication. Two classics, no half measures.

Growing Black & White Mix: 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.

Flowering runs the standard 9 weeks — no surprises, which in this business is a compliment. The flowering stage guide covers what each of those weeks should look like.

The yield is, in plain terms, heavy — 800 – 900 g/m² when she's looked after. Branches will need support before they need sympathy; see supporting heavy colas.

Breeder figures put THC around 20% — firmly in the strong band. The number speaks for itself; we'll not add adjectives to it.
