Lab IDs: Vermiculite (21-189-36, Vigoro); BioVermiculite (18-155-08, Biochar Pre-Composting Rogue). Values may vary by batch.
Scanning electron micrograph reveals the detailed pore network derived from the pine wood carbon matrix — delivering exceptional air porosity and water-holding efficiency.
Nutrients dispersed throughout the carbon matrix attract microroots. Roots penetrate interconnected pores, accessing stored water and bio-available nutrients for vigorous early establishment.
Uniform 2–4mm particle size creates optimal pore space, reducing waterlogging and compaction in professional potting mixes.
1.4× water-holding capacity vs vermiculite (641% vs 459% wt). Supports healthier root development and improves drought tolerance.
Provides an ideal habitat for beneficial microbes, promoting plant vigor while mitigating pathogens. Premium biochar soil conditioner.
Use as a direct replacement for vermiculite and perlite, formulated to replace peat moss in your existing blends — no reformulation required.
Produced from responsibly managed forestry residues. Permanently sequesters carbon. Net –3.5 tCO₂e/ST vs +1.03 for mined vermiculite.
Available in full truck loads (52 × 2CY supersacks) or full container loads (32 × 1.8CY). Shipped on 48″ × 48″ pallets, stackable two-high.
