OSH designs grow environments that empower cultivators to focus on what matters most: healthy plants, strong yields, and a business built to last.


Your cultivation facility is the foundation of your business. Getting it right means years of efficiency and reliability. At Open Source Horticulture (OSH), we design cannabis facilities that actually work. Every layout, system, and workflow decision strengthens your daily operations and long-term success. In cultivation, it’s often the smallest oversights that cause the biggest problems. A misplaced drain. An undersized chiller. A sensor that fails in peak season. Those details can set back production and eat into profits for years. Our team catches what others miss and coordinates every component so your facility runs as intended from day one. We focus on precision, communication, and practicality. No commissions. No upselling. Just experienced guidance backed by over 1.7 million square feet of licensed cannabis facilities.

A good floor plan isn’t just about plant placement. It’s about designing a space that flows. OSH plans cultivation facilities that maximize worker efficiency, space utilization, and biosecurity while setting the stage for precise environmental control.
Your plants depend on consistency. Temperature, humidity, airflow, light, and nutrients all have to work in sync. OSH integrates all cultivation equipment into one coordinated system that delivers precision, reliability, and control.
We align mechanical, electrical, and environmental systems so your lighting, irrigation, HVAC, CO₂, and benching operate seamlessly together. From early design through installation coordination, we make sure every component fits, functions, and communicates as one.
Great design is measurable. Every OSH project culminates in a complete, data-driven Basis of Design that defines your facility’s technical and financial roadmap. This documentation gives architects, engineers, and investors a clear direction forward.
Markets evolve, and your facility should evolve with them. We design spaces that grow, adapt, and perform year after year. Whether it is a phased buildout or a full-scale expansion, OSH plans every system with future scalability in mind.
Your facility should never hold you back. OSH designs grow environments that empower cultivators to focus on what matters most: healthy plants, strong yields, and a business built to last.
