Turnkey Irrigation Projects Retrofit Success: Black Pepper Greenhouses Converted for Cannabis

This project involved the transformation of an existing black pepper cultivation site into a highly controlled cannabis production facility in Thailand. The adaptation demonstrates Metzer’s ability to retrofit greenhouse infrastructure to meet the demands of modern medical cannabis cultivation.

Location: Thailand
Project Size: 2112 m2 ha
Crop: Cannabis
Irrigation Type: Drip Irrigation

How We Made It Happen

Challenge

The main challenge was converting eight traditional greenhouses—originally designed for black pepper—into a state-of-the-art environment compliant with strict cannabis production regulations. This required integrating advanced irrigation and water treatment systems, climate control, and full-spectrum security measures within an already built structure.

Resolution

Metzer delivered a complete irrigation solution based on precise drip irrigation using Gali PC pressure-compensated drippers, ensuring uniform delivery across all plants. The scope included a reverse osmosis (RO) system for water treatment, advanced air circulation and purification systems, and the full design and installation of security infrastructure—meeting the highest regulatory standards. The result is a productive and secure cannabis cultivation operation built on repurposed infrastructure with minimal disruption.
