SOP Implementation under GACP Standards
At Solar Farm—a GACP cannabis farm in Northern Bangkok—written, version-controlled SOPs cover propagation to packaging so each lot is consistent, traceable, and audit-ready for cannabis wholesale in Thailand.
- Mothers & clones: standardized cuts, rooting criteria, culling weak starts
- Nutrient mixing: fixed recipes; pH/PPM verified; sign-off before irrigation
- Irrigation: scheduled time/volume; logged per lot
- IPM: calendar scouting; action thresholds; only approved interventions; record date/room/lot/outcome
- Flowering controls: trellising and defoliation windows; weekly climate setpoints:
- Temperature
- Humidity
- CO₂
- VPD

- Post-harvest: cut criteria; drying curves; moisture and water-activity targets; curing checks

“SOPs only work when people do”
Employee Training and Knowledge Transfer
People and processes move together. Staff train on plant growth cycles, climate controls, IPM identification, and compliant data entry. Health and safety, PPE, and biosecurity are mandatory. Competency checks recur by role. New or revised SOPs trigger refreshers and sign-offs to keep execution uniform.
At Solar Farm, our GACP cannabis farm in Bangkok, we invest first in people so SOPs work on the floor.
- Paid onboarding with SOP shadowing and pass–fail assessments before solo work
- Role competency matrix; certification required per task and room
- Refreshers after any SOP change; sign-offs captured in training records
- Daily safety brief and PPE checks at shift start; biosecurity reminders at entries
- Cross-training across clone, veg, flower, and post-harvest to maintain coverage
- Deviation → root-cause → CAPA → targeted retraining, all documented
- Respectful-workplace policy, fair scheduling, and fatigue limits to reduce errors
- Coaching loops: supervisor walk-throughs with immediate feedback
All training records link to batch dossiers and audits. Result: fewer deviations, safer rooms, and consistent lots for licensed wholesale.

“Plants change by stage, controls must change with them”
Plant Monitoring by Growth Stage
Clone stage
- Track rooting daily around days 10–18
- Keep high humidity and stable temperature
- Transplant only vigorous clones
Vegetative stage
- Top to build an even canopy
- Run 18-hour light cycles
- Adjust fertigation for growth and maintain preventive IPM
Flowering stage
- Switch to 12/12
- Install trellis, prune strategically, and monitor CO₂, pH, TDS/PPM, and VPD
- Cull hermaphrodites and record actions

“Consistent lots start with consistent genetics”
Mother Plant Planning and Management
Genetics drive consistency. We start from verified seeds or trusted clones, feed to a stable schedule, and track each mother’s output. Plants are retired after defined hours and cuts to reduce drift. This protects clone quality for medical-grade production and wholesale reliability.

“If it isn’t logged, it didn’t happen”
Documentation and Compliance
Every run has records: propagation logs, nutrient and irrigation data, IPM actions, climate archives, and post-harvest documentation. Accredited third-party labs issue COAs per lot for potency, microbes, and contaminants. Batch dossiers, training records, and change-control files support audits and buyer reviews for cannabis wholesale in Thailand.
FAQs
