A.M.S. — Green House Seeds

Seb's take

Seb Silverback

Bred in the Swiss Alps from the rare Swiss Fragolina and the hybrid Swiss Gran Flora, and about as resilient as that origin suggests. Mint, earth and citrus on the nose, with a high that runs psychedelic, euphoric and energetic. The name is doing double duty — Amsterdam's airport code, and Anti-Mould Strain — which tells you exactly what she was bred to survive.

Growing A.M.S.: 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 — 700 g/m² when she's looked after. Branches will need support before they need sympathy; see supporting heavy colas.

Breeder figures put THC around 19.05% — firmly in the strong band. The number speaks for itself; we'll not add adjectives to it.

The aroma is citrus-forward: zest first, everything else in its wake.

Reported effects favour the creative: ideas arrive; whether they're good ones is between you and the morning.
