A medicinal cannabis greenhouse in Lesotho should be planned from the licensed activity, destination market, current GACP and GMP interpretation, product specification, site climate, security plan, quality system, and post-harvest workflow. Greenhouse equipment cannot certify a facility or guarantee export access. The RFQ should state which regulated process steps occur in each room and which party owns validation evidence.
Lesotho’s official investment and health guidance describes cultivation, processing, export licensing, seed-to-sale tracking, GACP, GMP, laboratory testing, and diversion controls. EMA’s revised GACP guideline covers medicinal plant starting materials. These sources make the design task broader than temperature and humidity control. The facility needs traceable materials, controlled movement, documented cleaning, calibrated monitoring, and a clear boundary between cultivation and later manufacturing steps.
Freeze the regulatory and product basis first
Before asking for a greenhouse price, identify the Lesotho licence pathway, target importing country, intended product, processing steps, testing route, and responsible quality team. Whole flower, biomass for extraction, and a finished medicinal product do not have the same facility or documentation needs. Obtain current written advice from the competent authorities and qualified regulatory professionals.
| Project decision | Buyer input | Evidence required in the design package |
|---|---|---|
| Licensed scope | Cultivation, primary processing, manufacture, storage and export activities | Room list, process map and responsibility matrix |
| Destination market | Importer, authority, product specification and current acceptance route | Regulatory basis list and unresolved approval items |
| Quality system | GACP, GMP interface, sampling, testing, release and record controls | Document map, equipment qualification list and data ownership |
| Security | Controlled perimeter, access levels, visitor process and product movement | Access zoning, alarm interfaces and diversion-control responsibilities |
| Product flow | Plant material, people, tools, waste, rejected product and cleaned equipment | Scaled flow drawings and segregation points |
Do not write EU-GMP-ready as a structure feature. GMP applicability can change by process step and destination-market interpretation. The buyer’s quality and regulatory teams should define the boundary. The greenhouse designer can then provide rooms, finishes, utilities, controls, data, and access features that support the approved plan.
Design climate control around product risk
Define temperature, humidity, light, air movement, filtration, pressure relationships where required, irrigation, and alarm duties for each crop stage and room. The responsible agronomist and quality team should approve the ranges. The equipment quotation should show sensor type, location, accuracy, calibration, data interval, retention, user permissions, alarm routing, and response to failure.
A single wall sensor cannot describe a large canopy. Ask for a mapping and qualification plan that covers representative zones, doors, supply air, return air, exterior walls, and known risk points. State how the system handles a failed sensor, communication loss, power interruption, stuck vent, fan fault, and unavailable backup source. Manual control should not erase the event record.
| Control area | RFQ detail | Acceptance evidence |
|---|---|---|
| Environmental sensors | Range, accuracy, location, calibration and replacement plan | Calibration certificates, mapping record and point-to-point check |
| Climate equipment | Vent, fan, cooling, heating, dehumidification and screen duties | Capacity basis, stage test, alarm test and recovery sequence |
| Data system | User roles, audit trail, retention, export, backup and time synchronization | Access test, sample report, change record and restore test |
| Utilities | Power quality, standby source, water treatment and critical loads | Load schedule, transfer test and defined safe state |

Join traceability to physical movement
Traceability works only when the building supports it. Identify where seed or clones are received, quarantined, identified, released, moved into production, sampled, harvested, weighed, transferred, rejected, destroyed, and dispatched. Show how labels remain attached to the correct lot and how the electronic or paper record follows every transfer.
Provide controlled points for clean tools, used tools, garments, waste, cleaning materials, samples, and retained material. Separate visitor routes from production movement. Decide how access is granted, reviewed, and removed. The security system and the quality record should use consistent zone names so an event can be investigated without guessing which room or door was involved.
Keep cultivation and post-harvest interfaces explicit
Harvest transport, drying, trimming, temporary storage, packaging, testing, and release can create more product risk than the greenhouse frame. List each step, room condition, maximum transfer time, container, cleaning method, sample point, hold status, and responsible party. The greenhouse supplier should not assume that the packhouse or processing area is included unless the quotation names it.
Humidity control in drying or storage must be sized from the material load, room envelope, outside conditions, air change, equipment heat, and intended operating range. Ask for normal and worst-case calculations. Provide condensate drainage, cleanable access, maintenance clearance, alarm response, and the means to document conditions. Do not accept a claim that one equipment model protects potency or prevents microbial failure.
Specify cleaning, pest control and maintenance access
Choose surfaces and details that can be inspected and cleaned for the approved risk level. Avoid inaccessible ledges, unsealed service penetrations, uncontrolled standing water, and equipment that can be serviced only by entering a clean crop route. The quality team should approve cleaning agents, contact materials, residue controls, and records.
Pest exclusion begins with the envelope, screens, doors, material inspection, and waste handling. Monitoring and control measures require a documented integrated pest-management plan. The system must also preserve the ventilation duty. A finer net that reduces airflow can shift the humidity and disease risk, so the climate and pest decisions need one calculation and one acceptance plan.
Use the greenhouse system overview to compare structure families. Use the commercial production greenhouse guide for general commissioning and handover. Neither page replaces the current medicinal-cannabis regulatory basis.
Commission records, alarms and fail states
Commissioning should verify room and equipment identity, sensor calibration, environmental mapping, controller sequences, user roles, audit trails, alarm delivery, access control, backup power, data backup, irrigation, sanitation points, waste routes, and operator training. Keep signed protocols, deviations, corrective actions, and final results.
Run approved failure tests before regulated production begins. Simulate loss of a critical sensor, controller communications, power, water, climate equipment, and alarm delivery. Confirm the safe state, event record, response time, escalation route, and recovery authorization. The qualification plan should distinguish supplier commissioning from the buyer’s regulatory validation.
