Perlite's low density drives a 55% freight premium despite weighing half as much. BioVermiculite delivers the lowest landed cost of the three amendments. Actual freight varies by origin, destination, and carrier.
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 –2.50 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.
