TerraRoot
Labs™

TerraRoot Labs™ produces small-batch, peat-free substrate systems for propagation, container crops, and collector tropical plants. Every formulation is mixed by measured formula, mechanically screened, and built around repeatable root-zone structure.

Measured Aggregate Structure

Screened aggregate classes are selected for each product so the finished mix has a consistent texture profile for its intended use.

Carbon + Mineral Support

Biochar and volcanic zeolite are included as carbon and mineral components that support a more stable container media profile.

Moisture + Air Balance

Each mix is built to balance moisture movement and open pore space when used in containers or trays with proper drainage.

Screened, Not Random-Scooped Perlite, castings, and structural inputs are handled for consistency before each finished product is packaged.

Ingredient Transparency

TerraRoot Labs™ substrate systems are built from disclosed ingredient classes including coco-based organic structure, screened horticultural perlite, biochar, natural volcanic zeolite, earthworm castings, and product-specific fertility amendments where appropriate. Exact ratios and processing sequences remain proprietary.

Ratio-Protected Disclosure
Structural Base

Coco + Screened Aggregate

Coco-based organic structure and screened perlite fractions create the physical foundation for air space, drainage, and moisture balance.

Mineral + Carbon

Biochar + Volcanic Zeolite

Biochar and volcanic mineral inputs are included to support media structure, retention, and a more stable container root-zone profile.

Organic Support

Earthworm Castings

Earthworm castings are screened and incorporated as an organic amendment across the substrate line.

Measured Root-Zone Structure

TerraRoot Labs™ formulations use mechanically screened aggregate fractions to support repeatable structure across propagation, container agriculture, and collector tropical environments.

Technical Specifications
Protocol 01

Biochar Component

Biochar is included as a carbon component within the finished media structure.

Protocol 02

Structural Aggregate Profile

Screened aggregate classes help maintain an open physical profile through normal watering and dry-back cycles.

Protocol 03

Volcanic Zeolite Component

Volcanic zeolite is included as a mineral component within the substrate profile.

Aggregate Calibration Protocol

TerraRoot Labs™ formulations are mechanically graded through calibrated screening processes designed to isolate practical particle-size classes. The reference images below use the metric side of a ruler, so the size callouts are listed as nominal screen-class ranges rather than exact particle guarantees. Because expanded perlite varies naturally in shape and fracture pattern, our grading targets functional architectural ranges that reduce excessive fines and help preserve open pore structure.

Calibration Matrices
TerraRoot Labs™ calibrated micro-fraction aggregate baseline check with scale
PROGENESIS

Micro-Fraction Class (~2–3 mm / 0.2–0.3 cm)

Fine-graded structural aggregates screened above the fines cutoff and below the coarse class. Built for plug trays, cell trays, and early root development where close seed contact still matters.

TerraRoot Labs™ coarse-graded structural aggregate baseline check with scale
YIELDFORGE

Coarse Structural Class (~3–6 mm / 0.3–0.6 cm)

Mid-range aggregate sizing screened between the micro and macro classes. Built for container production where drainage, moisture retention, and root-zone oxygen need to stay balanced.

TerraRoot Labs™ macro-fraction aggregate baseline check with scale
TROPICAL VELVET

Macro-Fraction Class (~6 mm+ / 0.6 cm+)

Large-profile aggregate structures retained above the coarse screen class. Built to maintain open pore space and strong drainage pathways for sensitive epiphytic root zones.
