As greenhouse production continues to expand worldwide, growers increasingly rely on horticultural consultancy to achieve stable yields, consistent quality, and efficient operations. In Japan, Zebra Greens partnered with Cultivators' experts to support the development and optimization of their hydroponic leafy greens production through structured training, technical guidance, and ongoing greenhouse cultivation support.
This collaboration demonstrates how targeted knowledge transfer and long-term horticultural advisory support can help growers successfully operate modern controlled environment agriculture (CEA) facilities.

From knowledge transfer to practical hydroponic cultivation
The cooperation between Cultivators and Zebra Greens began with an extensive training program designed to build a strong foundation in hydroponic leafy greens cultivation. To ensure practical relevance and effective learning, the training was delivered through multiple formats, including on-site training in the Netherlands, introducing European greenhouse standards, cultivation strategies, and best practices; in-country training sessions in Japan, adapted to local conditions, facilities, and operational realities; and remote online meetings, enabling continuous learning and follow-up support.
The program covered the entire cultivation cycle, including crop planning, climate management, irrigation and nutrient strategy, hygiene protocols, and harvest quality. In parallel, Cultivators provided technical guidance on greenhouse systems, equipment, and cultivation technologies, ensuring alignment between technical performance and crop needs.
Building a skilled cultivation team for greenhouse operations
Investing in high-tech greenhouses demands significant capital, making a successful launch critical for long-term profitability. Production losses during the startup phase can rarely be fully recovered, making a smooth and efficient beginning essential.
No new greenhouse starts without challenges; technical or managerial issues are inevitable. The key to success lies in having a well-prepared team capable of identifying and adapting to these potential setbacks.

Before introducing plants, Cultivators guided the Zebra Greens team through a structured startup process, ensuring that all technical equipment connected to the climate computer was thoroughly tested for functionality. While this may seem obvious, it is often overlooked when installation schedules are tight and equipment is installed in phases. The pressure to meet final delivery deadlines can easily lead to rushed completion. To avoid complications, Cultivators recommends testing every system as early as possible during the commissioning phase. Ensuring alignment between computer settings and equipment performance is crucial; Cultivators therefore recommends conducting at least two "dry runs" to verify that everything operates as intended.
The same principle applies to process-related tasks such as pot filling, precision seeding, substrate wetting, and material routing within the facility. Each step must be meticulously checked to ensure smooth operations.
A well-instructed workforce is vital for a seamless startup. Clearly define roles and responsibilities, and ensure your team understands potential issues from the outset. Awareness of potential issues enables timely and effective action.
By addressing these factors early in the project, growers can move more quickly toward stable production and profitability.
A key focus of Cultivators' horticultural consultancy approach is strengthening internal team capabilities. For Zebra Greens, this meant not only understanding crop physiology but also developing confidence in daily decision-making and operational workflows.
As part of this process, Cultivators trained the Zebra Greens team in key cultivation competencies, including crop monitoring and interpretation of plant signals, climate and irrigation adjustments based on crop stage, standard operating procedures for cultivation teams, aligning greenhouse technology with cultivation objectives.
By embedding knowledge within the organization, Zebra Greens builds long-term resilience and reduces dependency on external intervention.
Ongoing greenhouse cultivation support for stable quality and yield
To maintain stable production, predictable yields, and consistent quality, Cultivators continues to support Zebra Greens through biweekly greenhouse cultivation support sessions.
During these sessions, both teams review crop development and plant health, climate and irrigation performance, operational challenges and improvement opportunities, and progress against production targets.
This structured, ongoing support allows for early identification of risks and continuous optimization of the cultivation strategy, ensuring that performance improvements are sustained over time.
A partnership driven approach to CEA
Together with the Zebra Greens team, Cultivators acts as a long-term horticultural partner, combining hands-on training with strategic greenhouse cultivation consulting. This partnership supports Zebra Greens in moving confidently from project development to stable commercial greenhouse operation, while continuously refining their hydroponic production system.
