FSR-2089-0401 — Greenline Partner Nursery Survey
Routine scheduled survey of the Greenline Partner Nursery collection under the quarterly partner-site cadence. Full walk-through with the PhytoSense handset, baseline metrics captured, two minor advisories logged; no remediation required. Outcome CLOSED.
Engagement classification. Benign GCL-1 scheduled survey under a standing partner service contract. Single-technician dispatch permitted (no two-person rule for GCL-1). Standard horticultural PPE only; observation and baseline-capture engagement — no intervention planned.
1. Site & Conditions
| Field | Entry |
|---|---|
| Site name / client | Greenline Partner Nursery (Tier-2 propagation partner, contract VC-LEG-CT-0188) |
| Location / access | Three poly-tunnel ranges + one shadehouse; full-day staff access. Open-perimeter commercial grow. |
| Engagement type | Survey |
| Ambient temp / RH | 19 °C / 62 %RH; tunnels well ventilated |
| Conditions on arrival | Collection visually healthy; uniform growth; no pest pressure or disease signs observed on walk-through. |
| Public proximity | None — staff-only commercial site. |
2. Specimen Identification
| Field | Entry |
|---|---|
| Collection | Propagation nursery stock — 1,240 liners across 14 cultivar lines (ornamental + understock) |
| Accession scope | Partner-propagated under license; no GreenWorld vault stock on site. No UF- linkage. |
| Assessed GCL grade | GCL-1 (benign; no toxin, predation, or dispersal hazard) |
| Primary issues | None requiring action; two minor advisories logged (substrate-moisture variance in Range 2; light algal film on a bench in the shadehouse) |
| Hazards | None to personnel; standard horticultural handling. |
3. Work Performed
- Met partner grower; reviewed since-last-visit log and any flagged concerns (none raised).
- Walked all three poly-tunnel ranges and the shadehouse with the PhytoSense handset; captured baseline CVI and Fv/Fm per cultivar line (Section 4).
- Spot-sampled substrate pH and moisture across representative trays in each range.
- Visually inspected for pest, disease, and nutrient-deficiency signs across all 14 lines; none warranting remediation found.
- Logged two minor advisories: uneven substrate moisture on the Range 2 ebb-flow bench, and a light algal film on one shadehouse bench surface.
- Briefed the grower on both advisories with low-effort corrective suggestions; confirmed next quarterly survey date.
- Captured the survey baseline to the partner metric record; no departure/arrival delta as this was an observation-only visit.
4. Readings Captured
| Metric | Unit | Nominal Band | Arrival | At Securing |
|---|---|---|---|---|
| CVI — overall collection | % | ≥ 90 | 95.7 | 95.7 (survey baseline) |
| CVI — lowest line (Range 2 ebb-flow) | % | ≥ 90 | 91.4 | 91.4 |
| Chlorophyll Fluorescence (Fv/Fm) | ratio | ≥ 0.78 | 0.81 | 0.81 |
| Substrate pH (representative) | — | 5.8–6.2 | 6.0 | 6.0 |
| Substrate Moisture (Range 2 variance) | % | 60–70 | 54–72 (uneven) | 54–72 |

5. Parts & Consumables
| Item | Part / Lot | Qty | Notes |
|---|---|---|---|
| PhytoSense calibration check strip | PS-CAL-19 | 1 | Pre-survey handset verification |
| Substrate sample vials | LAB-VIAL-3 | 4 | Spot pH/moisture, returned for record |
6. Containment Actions
- PPE: nitrile gloves, eye protection (GCL-1 horticultural standard)
- Containment method: N/A (GCL-1 survey — no specimen handled or removed)
- Two-person rule: N/A (GCL-1)
- Field dispersal control: N/A — no hazardous material on site
- Decon on egress: N/A — standard handset/tool wipe-down only
7. Outcome & Disposition
| Outcome | Closed |
| Specimen disposition | Collection retained by partner; no specimen handled or removed. Observation-only survey. |
| Site left in condition | Collection healthy; two minor advisories briefed to grower; baseline logged. |
| Emergency procedure triggered? | No. |
8. Follow-Up Actions
- Grower to balance Range 2 ebb-flow bench drainage for even substrate moisture — owner: client — confirm by 2089-05-17.
- Grower to wipe down and dry the affected shadehouse bench to clear algal film — owner: client — confirm by 2089-05-10.
- Log survey baseline to partner metric record (metrics) — owner: T. Vetch — Done
- Next scheduled quarterly survey — owner: T. Vetch — 2089-08-02.
9. Lessons Learned
Note. Clean survey with a strong collection baseline (CVI 95.7%, Fv/Fm 0.81). The only items of note are low-severity husbandry advisories that the grower can resolve without GreenWorld intervention. Capturing the per-line baseline now gives the next survey a delta reference to catch drift early — the intended value of the scheduled-survey cadence under VC-SOP-0512. No SOP change recommended.
