Greenhouse Harvest & Post-Harvest Hydration Solutions

1. Overview & Business Value#

This comprehensive operational guide details the architecture, business workflows, configuration parameters, and execution steps for Greenhouse Harvest & Post-Harvest Hydration Solutions within SmartERP.

Manage morning harvest cutting schedules, cut-stage standards, sanitation of harvesting shears, and chemical hydration solutions.

2. Prerequisites & Security Access Groups#

• Required Modules: smarterp_commodity_export, smarterp_agri_traceability
• Security Groups:
  • Cold Chain & Packhouse Officer (Technical ID: smarterp_export.group_export_user)
  • Floriculture Quality Inspector (Technical ID: smarterp_export.group_export_qa)
  • Floriculture Export Manager (Technical ID: smarterp_export.group_export_manager)
• Master Data Dependencies: Greenhouse greenhouse blocks, rose stem varieties, cold storage temperature telemetry (2°C–4°C), Ethiopian Airlines Bole Cargo space bookings, and European auction buyers.

3. Step-by-Step Configuration & Execution#

Step 1: Navigating to the Module Interface#

1. Log into your SmartERP instance at https://smarterp.et/odoo.
2. Open the main App Switcher (grid icon in the top-left corner).
3. Select the Floriculture Export app icon.
4. From the top navigation bar, open Floriculture Export → Greenhouse → Harvest / Cold Chain / Packhouse / Air Waybills.

Step 2: Creating and Parameterizing Records#

1. Click the New button in the top-left control panel.
2. Complete the mandatory fields in the record form:
   • Greenhouse Harvest Batch (Mandatory): Block origin, stem length (cm), and cut date/time
   • Rose Variety & Head Size (Mandatory): Commercial cultivar (Rhodos, Red Naomi, Athena) and bud profile
   • Pre-Cooling Verification (Mandatory): Confirmed forced-air cooling record achieving 2°C–4°C core temperature
   • Bole Cargo e-AWB Number (Mandatory): Ethiopian Airlines booked air waybill identifier
3. Configure optional operational parameters and localized tags as required:
   • Cold Chain Logger ID (Optional): Digital temperature datalogger serial number placed in pallet
   • Auction Consignment Code (Optional): Royal FloraHolland auction lot reference
   • MoA Phytosanitary Seal Number (Optional): Official government export inspection security tag
4. Click the Save icon in the control bar to commit the record.

Step 3: Validating and Processing Transactions#

• State Transitions: Execute operational state progression (Harvested → Pre-Cooled (2°C) → Packhouse Sorted → Cold Truck Transit → Bole Airport Loaded → Cleared).
• Ledger & System Impact: Direct greenhouse labor and packaging costs absorb into crop inventory; e-AWB air freight dispatch recognizes export revenue in foreign currency.
• Audit Verification: Automated recording of author ID, timestamp, and immutable revision history.

Morning Harvest Timing & Cut-Stage Standards#

Cut roses are harvested strictly during cool early morning hours ($06:00 - 10:00$) before ambient greenhouse heat elevates plant transpiration:

• Cut Stage 2.0: Tight bud, sepals completely reflexed; ideal for distant transit markets (Japan, USA).
• Cut Stage 2.5 – 3.0: Petals loosening, point of color emergence; standard for European auction markets (Aalsmeer, Netherlands).
• Harvest Shear Sanitation: Shears are disinfected every 10 plants in quaternary ammonium solution (Menno Florades) to prevent spreading viral prunus necrotic ringspot virus (PNRSV).

Hydration Uptake Protocols#

1. Immediately upon cutting, stems are placed upright in plastic harvest buckets containing clean hydration solution.
2. Solution formulation:
   • Demineralized or Reverse Osmosis (RO) water ($pH\, 3.5 - 4.5$).
   • Aluminum Sulfate or Citric Acid as water acidifier.
   • Broad-spectrum germicide (slow-release chlorine or DICA) inhibiting bacterial vascular blockage in stem xylem vessels.
3. Buckets are tagged with RFID harvest batch cards and transferred to the packhouse receiving area within 30 minutes of cutting.

4. Advanced Configuration Points#

• Automated Actions & Scheduled Tasks (Crons):
  • Cold Chain: Alert temperature breach above 4°C (smarterp_export.ir_cron_temp_monitor): Runs every 15 minutes checking IoT temperature telemetry
  • Air Cargo: Track Bole cargo flight departure (smarterp_export.ir_cron_flight_status): Runs hourly checking Ethiopian Airlines cargo flight tracking
• Custom Print Templates & Reports:
  • Cold Chain Temperature Compliance Certificate
  • MoA Phytosanitary Export Inspection Dossier
  • Bole Cargo Air Waybill (e-AWB) & Pallet Manifest
  • Consignment Net Realization & Auction Settlement Summary
• Multi-Company Rules: Record-level security isolation under Company 1 (Ashewa Technology Solutions S.C.), preventing cross-company ledger leakage across parent and subsidiary legal entities.
