Why Choose Biology?

  • Disease Suppression

    Through competitive exclusion, healthier plants will out-compete disease pressures

  • Enhanced Nutrient Availability

    Improve nutrient cycling and facilitate nutrient absorption

  • Plant Resilience

    Better able to survive, adapt, and recover from all environmental stresses

  • Water and Nutrient Efficiency

    Utilize and maximize all of your inputs, both water and nutrient

  • Biomimicry

    Living biology mimics natural ecological processes in the greenhouse

  • pH Buffering

    Maintain a stable pH range for plants to thrive throughout the growing cycle

Grower Feedback

  • PCO-1 delivers consistent, high performance results with optimal moisture, aeration, and nutrition for healthier roots and stronger plants.

  • Very balanced mix of aeration vs. density. Doesn't compact down or become too dense.

  • Great water retention. Seeing better nutrient carryover with this mix, too.

Every component has been carefully selected to meet the demands of commercial growing:

Sphagnum Peat Moss delivers natural moisture retention while maintaining structure.

Plant-Based Compost enriches the media with organic nutrients and diverse beneficial microbes, increasing chemical buffering while offering disease-suppression qualities.

Perlite enhances aeration, preventing compaction and supporting optimal root oxygenation.

Starter Fertilizer provides essential early nutrition for a strong, uniform start.

Wetting Agent ensures even water distribution throughout the media, from first irrigation to final harvest.

Our Process

Our thermophilic composting method utilizes heat-loving bacteria and fungi to break down carbon-rich materials, raising the internal temperature of the compost piles. This process not only eliminates weed seeds and pathogens but also results in a biologically rich certified organic compost that is approved for use in organic production systems with the OMRI stamp of approval. This certification ensures that the compost is more than just a filler, it's a living, functional amendment designed to elevate plant performance at every level.

The Result?

A grower mix that drains freely yet holds essential moisture, supporting faster establishment, healthier roots, and stronger plants — from transplant to finish.
