Vermiculite and BioVermiculite values from independent lab analysis. Perlite values from published industry data. Values may vary by batch and grade.
Engineered for biology, optimized for drainage, designed for sustainability — BioVermiculite™ exceeds conventional growing media components across every key metric.
BioVermiculite™ incorporated as a 1:1 volumetric replacement across two independent commercial trials. BioVermiculite™ is shown on the right in each comparison. Trials conducted under standard commercial production conditions.
Commercial greenhouse propagation facility. Standard vermiculite substrate (left) vs. BioVermiculite™ substituted 1:1 (right).
Equivalent shoot development. BioVermiculite™ (right) shows comparable root mass with improved moisture retention between irrigation cycles.
Commercial nursery container production. Standard vermiculite substrate (left) vs. BioVermiculite™ substituted 1:1 (right).
Superior shoot emergence and comparable root development in BioVermiculite™ (right) vs. standard vermiculite substrate (left). Demonstrates performance parity or better as a 1:1 substitution in conifer nursery production.
