Based in Portugal’s Alentejo region, Herdade das Barrocas combines agricultural heritage with modern cultivation technology. Its philosophy, “Where nature meets technology,” reflects a commitment to working in harmony with the natural environment while using advanced production systems to cultivate medical cannabis for regulated markets.
The partnership brings together HDB’s EU-GMP cultivation and processing capabilities with Curaleaf Laboratories’ MHRA-approved manufacturing, quality assurance and distribution infrastructure in the UK. Together, the companies aim to strengthen supply continuity, support pharmaceutical quality and expand the range of cannabis-based medicinal products available to UK specialist prescribers.
What Sets Herdade das Barrocas Apart From Other Medical Cannabis Producers?
Herdade das Barrocas has developed a distinctive approach to medical cannabis cultivation, combining controlled-environment agriculture with an emphasis on genetics, quality and environmental responsibility.
The company operates on a 240-hectare agricultural estate in Alentejo, Portugal, where its high-end production facilities occupy a relatively small proportion of the wider property. The estate includes traditional agricultural landscapes, olive trees, cork and oak pastures, and meadows. HDB states that its wider agricultural activities, including these traditional farming areas, are bio-certified.
This connection to the land sits alongside a technologically advanced medical cannabis operation designed to meet the requirements of regulated pharmaceutical markets.
HDB’s approach combines:
• Automated glasshouse cultivation and environmental management.
• Specialist cannabis genetics and tissue culture propagation.
• Controlled drying, processing and packaging in validated cleanrooms.
• In-house analytical testing and dedicated quality management.
• Solar energy generation and treated irrigation water.
HDB describes its ambition as producing superior-quality medical cannabis flower while balancing technological innovation with sustainability and respect for the natural environment.
Its cultivation and processing operations are EU-GMP-aligned, providing an important foundation for its work supplying international medical cannabis markets.
A State-of-the-Art Pharmaceutical Cultivation Facility
At the heart of Herdade das Barrocas’ operation is a 4,000 m² glasshouse, designed to combine natural sunlight with automated environmental controls.
The facility uses a controlled-environment approach to manage the conditions that influence plant development, helping provide a consistent cultivation environment across production cycles.
Key features include:
- Automated climate control: Heating, ventilation and air conditioning systems manage temperature, humidity and airflow.
- Controlled lighting: Automated lighting systems, blackout screens and shading systems help regulate the growing environment.
- CO₂ injection: Pharmaceutical-grade CO₂ injection forms part of the facility’s environmental management systems.
- Automated fertigation: Irrigation and nutrient delivery are managed through automated systems.
- Natural sunlight: Glasshouse production makes use of the region’s strong solar radiation and natural light spectrum.
By combining natural light with automated environmental management, HDB aims to create a controlled growing environment that supports its cultivation and quality objectives while making use of the local climate.
This approach reflects the company’s wider philosophy of combining nature with technology rather than relying exclusively on either traditional agricultural methods or energy-intensive indoor cultivation.
Precision Cultivation and Environmental Management
Consistency between batches is an important consideration in medical cannabis production. Cultivation conditions, genetics, harvesting and post-harvest handling can all influence the characteristics of the finished flower.
Herdade das Barrocas addresses these considerations through a combination of environmental management, controlled irrigation, specialist genetics and defined processing procedures.
Water Treatment and Irrigation
Water quality is an important part of controlled cultivation. HDB uses water from onsite wells and collected rainwater, which is treated through a reverse osmosis system before being used for irrigation.
Reverse osmosis provides a water-treatment process that removes many dissolved impurities, supporting greater control over the water supplied to the plants.
Combined with automated fertigation, this system enables HDB to manage irrigation and nutrient delivery within its wider cultivation process.
Solar Energy and Resource Efficiency
HDB’s glasshouse benefits from natural sunlight, helping reduce reliance on artificial lighting compared with a fully indoor cultivation model.
The company also operates a 1,200 m² solar power installation, which supplies a proportion of the energy used by its facilities.
These features reflect HDB’s stated objective of reducing its environmental footprint while maintaining the controlled conditions required for medical cannabis production.
The combination of natural light, solar energy and treated irrigation water provides a distinctive aspect of HDB’s approach, bringing resource efficiency into its wider cultivation strategy.
Genetics, Tissue Culture and Batch Consistency
Cannabis genetics play an important role in the characteristics of individual cultivars, including their cannabinoid and terpene profiles.
Herdade das Barrocas works with cannabis breeders in California, drawing on specialist genetic expertise and cultivar knowledge to develop its production portfolio.
The company also operates a tissue culture laboratory and nursery, which it uses to produce clean, healthy and genetically consistent clones for cultivation.
Tissue culture techniques allow plants to be propagated under controlled conditions. When combined with appropriate selection and cultivation practices, this can help maintain genetic consistency across successive plantings.
HDB identifies this approach as an important part of its strategy for maintaining batch consistency and achieving the desired cannabinoid and terpene characteristics of its cultivars.
Its genetics programme brings together:
- Collaboration with specialist cannabis breeders.
- Cultivar selection based on desired characteristics.
- Tissue culture and nursery propagation.
- The use of genetically consistent planting material.
- Continued attention to batch consistency and product quality.
By combining genetics expertise with controlled cultivation, HDB aims to establish a repeatable foundation for producing medical cannabis flower for demanding regulated markets.
EU-GMP Processing and Controlled Post-Harvest Handling
Medical cannabis quality depends on more than the conditions in which plants are grown. Harvesting, drying, handling, testing and packaging are also important stages in the production process.
Herdade das Barrocas has built, implemented and validated cleanrooms for processing, drying and packaging its flower within an EU-GMP environment.
The company describes a series of procedures designed to support consistent handling and quality management throughout these stages.
Integrated Harvesting and Processing
HDB states that harvesting and processing are coordinated for each greenhouse bay, with both processes starting and finishing on the same day.
This integrated approach supports the coordination of crop handling and post-harvest operations, helping minimise unnecessary delays between harvesting and processing.
Controlled Drying
Following harvest, flower undergoes a slow drying process in a dedicated 50 m² drying room.
HDB describes drying at low temperatures under controlled humidity and airflow. These parameters are important considerations in post-harvest processing, as drying conditions can influence the moisture content and quality characteristics of the finished flower.
The use of a dedicated drying environment allows these conditions to be managed as part of the company’s wider processing procedures.
Stainless-Steel Contact Surfaces
HDB states that, from harvesting onwards, its flowers come into contact only with stainless-steel surfaces.
Stainless steel is widely used in regulated processing environments because it can be cleaned effectively and is suitable for controlled handling processes.
This detail illustrates HDB’s attention to the materials used throughout its post-harvest workflow.
Total Quality Management
HDB describes its quality approach as part of a Total Quality Management (TQM) framework applicable across the facility and its equipment.
The company also operates an internal laboratory that performs much of its analytical testing for its own production, supported by a dedicated quality structure.
Together, these measures form part of HDB’s approach to maintaining control over cultivation, processing and product quality within its regulated production environment.
