Facility Design and Operational Principles of an EU-GMP Medical Cannabis Production Campus
Our facility has been designed to support the cultivation of medical cannabis under GAP-aligned agricultural principles and the processing of products under GMP-compliant pharmaceutical standards. Because the project is intended to supply both semi-finished and finished products to the market, every stage of cultivation, handling, and processing must be fully controllable, traceable, and verifiable.
Design Philosophy
From the earliest planning stages, the project has focused on raw material quality, the health and genetic consistency of seeds and mother plants, and the protection of cultivation areas from fungi, viruses, bacteria, and parasites. At the same time, documented Standard Operating Procedures, qualification, validation, and full traceability have been treated as core requirements rather than optional additions.
A defining regulatory condition of the project is that cultivation and processing must be carried out within the same facility. Since the harvested product cannot legally be processed in a separate external location, the entire campus has been designed as a fully integrated production and processing environment.
Building Materials and Cleanroom Approach
Early design studies showed that standard industrial construction materials would not be sufficient for a facility of this kind. Smooth, cleanable, and crack-resistant surfaces are essential in order to reduce the risk of microbial contamination and support repeated decontamination procedures.
For this reason, insulated wall and ceiling panels commonly used in cleanrooms and sterile environments were selected. These materials provide both hygienic surfaces and the high level of thermal insulation required to maintain stable internal temperatures. Walkable ceiling panels were also chosen so that technical systems installed above the rooms can be accessed without entering controlled production areas.
For flooring, seamless poured epoxy was selected due to its chemical resistance, water impermeability, and ease of cleaning.
Multi-Room Cultivation Strategy
Because plants require different light, nutrient, and environmental conditions at different stages of development, the facility has been designed around a multi-room cultivation model. This approach also reduces the risk of cross-contamination and helps limit the spread of disease between production zones.
Dedicated propagation rooms will be used for cloning in order to preserve plant standardization. From there, plants will be transferred into cultivation rooms, where they will complete their growth cycle before moving into processing.
Environmental Control and Decontamination
Each cultivation room has been designed with its own environmental control logic. Rooms can be maintained under negative or positive pressure depending on operational needs, especially during decontamination cycles involving hydrogen peroxide in vapor phase or diluted solution form.
The facility design includes CO2 sensors, hydrogen peroxide sensors, airflow control systems, filtration systems, and automated warning mechanisms. If pressure values move outside the intended range, both visual and audible alarms will notify operators immediately.
The air handling design also ensures 100 percent fresh air supply where required, helping maintain oxygen balance and environmental quality within the growing areas.
GMP Processing Area and Controlled Workflow
Within GMP areas, material movement and personnel movement have been planned carefully in order to reduce contamination risk and protect workflow integrity. Material pass-through systems are used where needed, while electrically locked doors and light-based transition warnings help maintain environmental separation and room pressure stability.
Cleanroom air quality is supported through controlled air-change rates, H14 HEPA filtration, and low-level extraction strategies. HVAC systems serving GMP areas are designed with full redundancy, allowing backup systems to automatically take over if needed in order to preserve pressure balance and environmental continuity.
Automation, Monitoring, and Data Recording
A central automation system will continuously monitor airflows, pressure, temperature, and humidity values in each room. All critical environmental parameters will be recorded in real time, supporting both operational control and quality assurance.
In case of any deviation, the system is designed to alert users and quality teams immediately, allowing pre-defined procedures to be activated without delay. This structure is essential for maintaining GMP discipline and ensuring repeatable, validated conditions.
Water, Nutrient, and CO2 Management
Each cultivation room will receive water and nutrient inputs through dedicated hydroponic pipelines. These lines will be connected to central storage tanks and dosing systems, and a dedicated software platform will automatically distribute water and nutrients according to the needs of each room.
Water supplied from the municipal network will pass through pre-treatment and specialized filtration systems. Its quality will be continuously monitored through a validated online control system, helping prevent exposure to undesirable minerals or microorganisms.
The rooms will also be connected to a central CO2 system, allowing air quality and growth conditions to be adjusted according to production requirements.
Lighting and Cooling Systems
The facility will operate entirely without daylight in the cultivation areas. Instead, plants will be grown under artificial lighting systems tuned to the required wavelengths.
Because these lighting systems generate substantial heat, additional filtered cooling equipment has been integrated into the environmental design. Conditioned water will be used in cooling units in order to avoid contamination risks. Separate chiller systems are planned for processing and cultivation areas, and each chiller will include multiple independent circuits to improve reliability.
Lighting schedules will be managed in a staggered manner so that energy use remains more stable throughout the day.
Raw Material Entry and Quarantine Procedures
All incoming raw materials will first be registered and weighed. Certified materials will be directed to pre-storage, while uncertified inputs will be isolated in quarantine rooms. Materials held in quarantine will be reviewed in the environmental laboratory before being approved for use.
If a material is found to be unsuitable, it will either be decontaminated where appropriate or removed from the facility in accordance with microbiological safety requirements.
Harvest, Processing, and Final Storage
After cultivation, harvested plants will move to cutting rooms and then onward to either drying rooms or wet-processing rooms. Material from drying will proceed to dry packaging, while wet-processed product will move into filling systems.
Finished products will then be transferred into a secure final storage room after barcode labeling and recording procedures have been completed. The final storage area is designed for high physical protection and controlled inventory management.
Plant waste generated during cutting and related processes will be collected separately and handled in accordance with regulations. Where permitted, treated plant waste may be repurposed as supplementary agricultural fertilizer.
Software and GMP Compliance
All major devices used in cultivation, cutting, drying, wet separation, and filling are planned as data-enabled systems. A GMP-compatible software environment will continuously supervise the equipment and confirm that production remains aligned with defined operating standards.
The same software structure will also support documentation, equipment tracking, and the follow-up of qualification and validation records, including IQ and OQ documentation.
Operational Outlook
The facility is planned as a 24-hour operation and is expected to create a meaningful source of employment in the region. More importantly, it is being built as a scalable, integrated, and pharmaceutical-grade production campus capable of serving the evolving European medical cannabis market with consistency, quality, and regulatory discipline.
