How to grow Double White
Seb's take
White Widow crossed with the 1997 Cup-winning Great White Shark, fruity and pungent in equal measure. Heavy-yielding and easy enough to grow without fuss, at 17 to 20% THC — two Amsterdam names combined without diluting either, and dense nuggets to show for it.
Growing Double White: 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.
A solid, dependable yield — 450 – 600 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 20% — firmly in the strong band. The number speaks for itself; we'll not add adjectives to it.
