How to grow Amherst Sour Diesel
Seb's take
Chemdawg and Amherst Super Skunk behind a lineage the breeder keeps deliberately vague — 70:30 Sativa-leaning, and unbothered by the mystery. At 27% THC the high is long, euphoric and considerable; give her the headroom outdoors and she will happily reach three metres. Indoors she stays modest and still delivers 400-600g/m² in 65-70 days.
Growing Amherst Sour Diesel: 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 10 weeks — no surprises, which in this business is a compliment. The flowering stage guide covers what each of those weeks should look like.
Tall, at 300 cm or better. Indoors that means training from early on; outdoors it means picking a spot the neighbours can't see over.
A solid, dependable yield — 400 – 600 g/m² under decent conditions. Nothing that requires bragging; everything that justifies the effort. The yield lesson covers getting to "decent conditions".
