How to grow Auto Black JH
Seb's take

Growing Auto Black JH: what to expect
An autoflower: she flowers on age, not on light hours, which removes the single biggest way to get the schedule wrong. The auto versus photoperiod lesson explains what that changes — which is nearly everything.
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.
A middling 120 cm or so at maturity — tall enough to yield, short enough to manage. Standard tent territory; the light planner sorts the hanging height.
A solid, dependable yield — 450 g/m² under decent conditions. Nothing that requires bragging; everything that justifies the effort. The yield lesson covers getting to "decent conditions".
Breeder figures put THC around 18% — firmly in the strong band. The number speaks for itself; we'll not add adjectives to it.
The nose runs sweet — dessert-adjacent, without apology.
Reported effects lean relaxed — the sitting-down sort.
