Biochar Propagation Matrix

PROGENESIS

PROGENESIS is a fine-screened, peat-free propagation substrate built for seed trays, plug cells, small starts, and early root development. The mix is designed for close seed contact, even cell filling, balanced moisture movement, and steady oxygen availability during germination and early plug formation.

BLACKACRE SUPPLY CO.™ Progenesis Biochar Propagation Substrate showcasing a precise tweezer seed-sowing workflow

Ingredient Profile

PROGENESIS is built from a fine-screened propagation base using mineral, carbon, and organic inputs selected for tray handling, early moisture balance, and clean plug development. Each batch is mixed by measured formula and screened for a consistent fine texture. Ingredient categories are disclosed for transparency while blend ratios remain proprietary.

Label Disclosure

Base Structure

Coco Coir + Fine Horticultural Perlite

Expanded coco coir and fine-screened horticultural perlite provide the physical base for plug-cell filling, moisture movement, and oxygen availability in propagation trays.

Mineral + Carbon

Biochar + Volcanic Zeolite

Biochar and natural volcanic zeolite are included as carbon and mineral components within the fine propagation profile.

Biological Amendment

Earthworm Castings + Micronutrient Support

Earthworm castings and a controlled-release micronutrient component are included as low-rate support inputs in the finished formula.

Component Preparation Protocol

Before blending, key inputs are prepared for the role they play in the finished propagation substrate. Coco-based materials may be rinsed, buffered, screened, and batch-checked as needed to support cleaner handling, better calcium and magnesium balance, and more consistent early root-zone behavior.

Prepared Before Blending

Coir Preparation

Buffered When Needed

Coco-based inputs are reviewed before use and may be rinsed or buffered when a component lot calls for additional preparation.

Seed-Sensitive QC

Salinity-Aware Handling

Because propagation work is sensitive to excess salts, PROGENESIS is built with extra attention to EC awareness, moisture movement, and fine texture consistency.

Internal Review

Batch Checks

Internal quality checks may include EC review, pH awareness, moisture behavior, and texture inspection depending on the component lot and finished batch.

Aggregate Calibration Reference

PROGENESIS uses the micro-fraction class from the BLACKACRE SUPPLY CO.™ screening workflow. The image is shown against the metric side of a ruler; sizing represents a nominal screen-class range rather than a guarantee that every particle is identical.

Micro Class

$PROGENESIS micro-fraction perlite class measured against the metric side of a ruler$

Reference Image

Micro-Fraction Class

Fine aggregate sizing screened above the fines cutoff and below the coarse class, selected for propagation plugs, tray cells, and small-volume seed starting work.

Nominal Range

~2–3 mm / 0.2–0.3 cm

Small particle architecture helps improve seed contact and even cell filling while still preserving air movement inside compact propagation volumes.

Natural Variation

Screened, Not Machined

Perlite is a natural expanded volcanic material. Screening targets a functional class range, so small variation within the finished mix is expected.

Substrate Architecture Check

A closer look at the PROGENESIS mix. The fine-screened mineral fraction, carbon component, and organic amendments are blended for even filling and reliable handling in small plug cells.

Protocol 03

Cohesive Plug Extraction

Early root development shown straight from the cell tray. The roots bind the mix into a clean plug, which can help reduce disturbance during transplanting.

Use Notes

Fill trays or cells loosely, level gently, and water carefully after sowing. Do not compact heavily. Use containers or trays with drainage. Store sealed and dry until use.

Customer Use

Best For

Seeds, Plug Cells, and Small Starts

Seed starting, propagation trays, plug cells, small-cell starts, herbs, vegetable starts, and early-stage seedlings.

Fill Disclosure

Settling Allowance

Labeled at 4 dry cups. Packed above stated volume to allow for natural settling from screening, packing, and transit.

Handling

Fine Texture, Light Fill

Use a loose fill and avoid heavy compression so the fine aggregate class can maintain air space inside small cells.

Package

4 Dry Cups

Measured by dry volume. Natural variation in perlite shape, color, and particle size is expected.
