PCO-1 is a biologically active growing media designed for consistent performance, strong roots, and efficient water and nutrient use.
At Purple Cow Organics, we believe in the power of nature to nurture growth. Our PCO-1 blend starts with a foundation of 100% plant-based compost, proudly produced in the Midwestern United States. This compost is the cornerstone of all our blends, driving biological diversity and consistent results.
Our thermophilic composting process harnesses heat-loving bacteria and fungi to break down carbon-rich materials. High temperatures eliminate weed seeds and pathogens while cultivating a biologically rich, OMRI Listed compost approved for organic production systems.
The result? A compost teeming with beneficial microorganisms that improve nutrient availability, root health, plant resilience, and water-use efficiency.
Even if you’re a conventional greenhouse grower, organic certification is a key signal of quality and integrity. It ensures that compost isn’t just filler—it’s a living, functional amendment designed to elevate plant performance.
Together, these components make PCO-1 a biologically active, high-performance substrate engineered to deliver consistent, vigorous growth across a wide range of greenhouse crops.
