Key item features

  • Massive Expansion: Each 11-pound compressed block expands to 75 quarts (2.5 cubic feet) of fluffy growing medium when hydrated with 3-4 gallons of warm water, filling 7-10 standard seed trays.
  • Superior Growth: Triple-washed low-salt coco coir (EC <0.5) provides ideal moisture retention while maintaining 30% air porosity for optimal root oxygenation and faster germination rates.
  • Versatile Medium: Perfect for seed starting, microgreens, hydroponics, indoor houseplants, raised beds, and soil amendment, working as a sustainable peat moss replacement with a neutral pH (5.5-6.5).
  • Premium Processing: Aged 18+ months and buffered to remove excess salts, this coco coir is compressed at optimal density for easy breaking and sourced from mature coconut husks for consistent fiber quality.
  • Multi-Purpose Applications: Ideal substrate for reptile terrariums, worm composting bins, mushroom cultivation, and moisture control in container gardens, naturally resistant to fungal growth.
  • Enhanced Root Growth: Supports successful germination and healthy root development, allowing roots to absorb nutrients while maintaining pH balance and shedding excess water saturation.
