Genetics, Propagation & the Mother Room
Uniformity is a decision you make in propagation — clone clean, feed light, root right, and never let a viroid touch a blade.
Genetics & Source Selection
The Mother Room
Mother-Plant Health, Selection & Sizing
Keeping stock plants vegetative, vigorous, and clean — with the exact light, feed, NPK bias, and rotation targets, plus the math for how many mothers you actually need.
SOP: Mother-Plant Maintenance
The flagship stock-plant routine — light, feed, pruning, HpLVd screening, rotation, and sizing — as a printable procedure.
Cloning & the Rooting Environment
The Rooting Environment — Coco vs. Rockwool
Why rootless cuttings die from too much light, and the exact dome RH, air temp, PPFD, plug EC/pH, hormone, and rooting timeline that get you ≥80% success.
SOP: Clone / Cutting
The flagship cutting procedure, step by step from plug pre-soak to transplant, targeting ≥80% rooting success.
Transplant Progression & HpLVd Biosecurity
Transplant Progression — Trigger Every Move on Roots
Plug → block → slab/pot, with the exact visual and dryback triggers for each move, plus how the first irrigation is timed.
HpLVd Awareness & Tool Sterilization
The hop latent viroid that silently halves potency in ~90% of surveyed CA facilities — how it spreads, how to test, what sanitation actually works, and the only reliable cure.
Pheno-Hunting, Selection Scoring & Tissue Culture
Pheno-Hunting & the Selection Scorecard
How to run a structured pheno-hunt at commercial scale — pop size, how many seeds to find a keeper, a weighted scoring rubric across yield, potency, morphology, and grow-ability, and the two-stage cull that turns 200 seeds into one mother.
Tissue Culture vs. Cuttings — When to Move to a Lab
The real trade-offs between traditional cuttings and micropropagation — multiplication rate, footprint, contamination risk, and cost — plus the stages of a TC pipeline and the economic break-even that tells you when a clean-stock lab pays for itself.
HpLVd Eradication & Mother Scheduling at Scale
Running an HpLVd Eradication Program
Beyond awareness — the facility-level program to drive a viroid out and keep it out: a tiered indexing cadence, the meristem + thermotherapy clean-up pipeline, zone-based containment, water-line control, and re-testing gates before clean stock re-enters production.
Mother Scheduling & Capacity Planning at Scale
The production-math layer above single-mother care: converting a flower-room turn schedule into a weekly cutting demand, sizing the mother bench with buffers, staggering mother rotation so output never dips, and staging clean replacements through a rolling refresh — with a worked example.
