Why we ship cuts in from California and hold them to F4.

14 February 2026 · 5 min read

The short version: California has spent the last twenty years accumulating genetics you cannot find anywhere else. Cuts from Lumpy’s, Supernova Gardens, Doc D, Wizard Trees — those are the work of specific people with specific names, and every cut carries the signature of its breeder. We bring cuts in physically — not seeds “inspired by,” but live material in sealed carriers — and we work with that material directly.

What S1 is, and why it matters.

A cut is a clone. A clone does not reproduce true from seed, so the first job is to get seeds out of it. We make S1 (selfed first generation) by pollinating the plant with its own reversed pollen. The result is offspring carrying the genes of a single parent, in which we look for phenotypes as close to the mother as possible. That is the first culling pass.

F2, F3, F4 — why four seasons.

From the strongest S1 seedlings we select a pair — a mother and a father — and make F2. Then we repeat: F2 → F3 → F4. Each generation we keep only what reproduces the character of the mother cut: aroma, bud density, flowering speed, mould resistance. By F4 the phenotype is locked in tightly enough that 90% of the offspring repeats the mother cut. That is what a stabilised line means.

Why two independent grow cycles.

Before a line lands in the catalogue we run it once more — in a different room, on a different substrate, with different water. If the terpene profile and structure hold, we release it. If anything drifts, we go back to selection. The process is slow, but it is the only way to sell aroma instead of a lottery.
