Two phenotypes of the 1998 original Black Domina crossed back into each other, doubling down on a name that already meant business. Yields run to a full kilo per plant outdoors, at a medium potency that asks little fuss for the return.

Growing Double Black: 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 8 weeks — no surprises, which in this business is a compliment. The flowering stage guide covers what each of those weeks should look like.

A solid, dependable yield — 500 g/m² under decent conditions. Nothing that requires bragging; everything that justifies the effort. The yield lesson covers getting to "decent conditions".
