Red Rock delivers a straightforward, dependable approach to growing, providing cultivators with a substrate as rugged and reliable as the landscapes that inspired its name. Emphasizing quality, uniformity, and pristine performance, Red Rock has earned the confidence of growers seeking precise control over their cultivation spaces.
The core of Red Rock’s product is high-grade expanded clay aggregate—a lightweight, porous, and neutral medium formed by heating natural clay to temperatures exceeding 2,000°F. This process creates a substrate that excels in airflow, drainage, and stability, offering a clean, pH-consistent base perfect for hydroponics, aquaponics, and soilless systems.
Carefully refined to remove dust and ensure even sizing, every batch promotes steady root growth and efficient nutrient delivery. Whether used in deep water culture, ebb and flow, or drip irrigation setups, Red Rock’s substrates provide a durable, reusable solution that drives robust root systems and streamlined, effective growing cycles.
