Grow with PCO: PCO-1 Professional Growing Media | Organic Transplant Mix
Grow with PCO: A Foundation Rooted in Biology
At Purple Cow Organics, we believe better growing starts below the surface. Through Grow with PCO, we share practical education, product knowledge, and soil biology insights to help growers make informed decisions from transplant to harvest.
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.
The Power of Thermophilic Composting
Our thermophilic composting process harnesses heat-loving bacteria and fungi to break down carbon-rich materials. High temperatures help eliminate weed seeds and pathogens while cultivating a biologically rich, OMRI Listed compost approved for organic production systems.
The result is a compost teeming with beneficial microorganisms that support nutrient availability, root health, plant resilience, and water-use efficiency.
Why Organic Certification Matters
Even if you are a conventional greenhouse grower, organic certification is a key signal of quality and integrity. It ensures that compost is not just filler — it is a living, functional amendment designed to elevate plant performance.
As part of Grow with PCO, our goal is to help growers better understand what goes into professional growing media and why each ingredient matters.
What Makes PCO-1 Different?
- Grower Grade Sphagnum Peat Moss: Balances water-holding capacity, structure, and pH.
- Coarse Perlite: Improves porosity and oxygen diffusion in the root zone.
- Professional-Grade Wetting Agent: Ensures even moisture distribution.
- Balanced Starter Nutrient Charge: Supports early root development.
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.
