This is a moisture-retentive, peat-replacement terrestrial houseplant mix with added aeration.

It is designed for plants that naturally grow on the forest floor, not in canopy or epiphytic conditions. This mix sits firmly in houseplant soil territory, prioritizing steady moisture, softness, and root contact over speed of drainage or extreme airflow.

Think classic tropical understory conditions—consistent moisture, buffered roots, and a forgiving but not careless substrate.

COMPONENTS

(Formulated for moisture retention with balanced aeration)

Coco Coir – Primary peat-replacement matrix. Provides continuous moisture retention, uniform root contact, and a soft structure that supports fine and fibrous roots while drying more cleanly than peat.

Orchiata Bark – Structured organic aeration. Introduces durable pore space, slows compaction, and improves oxygen availability within an otherwise moisture-dominant mix.

Perlite – Lightweight aeration component. Interrupts the fine matrix to preserve gas exchange and reduce the risk of total saturation.

Worm Castings – Fine, biologically active fraction. Contributes low-level nutrition, microbial life, and increased moisture retention; a major reason overpotting must be avoided.

Biochar – Nutrient buffering and microbial habitat. Increases CEC, moderates nutrient swings, and adds long-term biological stability without acting as a fertilizer.

This mix uses a coir- and casting-based matrix to replace peat while maintaining a biologically active, moisture-dominant structure. Aeration components are included to prevent complete collapse, but the mix is intentionally slow-drying and soil-like in behavior.

This is not a chunky or structural mix. It is designed to behave like a modern, improved houseplant soil.

WHO THIS MIX IS FOR

This mix is designed for standard tropical houseplants that prefer consistent moisture, moderate aeration, and a soft, biologically active root zone.

Best suited for:

• Forest-floor tropicals

• Plants with fine to medium root systems

• Species that struggle in fast-draining or chunky mixes

• Growers seeking a peat alternative with familiar soil behavior

This mix favors moisture stability over oxygen dominance.

NON-NEGOTIABLE RULES FOR SUCCESS

• Never overpot. Coir and castings together will compact if excess volume is used.

• Use containers sized tight to the root ball.

• Water thoroughly, then allow partial dry-down before rewatering.

• Best results occur in warm, temperate environments.

Overpotting is the primary failure mode for this mix.

OPTIONAL BOOSTER PACKS

Optional booster packs are formulated to work with this mix and contain 100% natural ingredients to support establishment after repotting.

They do not replace regular feeding.
They support plants for approximately 1–2 months while roots re-establish.

Mix thoroughly into the substrate before use.
Do not apply as a surface top-dress.

INGREDIENT QUALITY & FORMULATION

All mixes are hand-blended to order using high-quality ingredients sourced from reputable suppliers. Nothing is pre-mixed or mass-produced.

These formulations were developed with professional grower input and refined through extensive testing across multiple climates and growing conditions.

USE & RESPONSIBILITY

Plant performance depends on environment and cultural practices. We are not responsible for outcomes resulting from improper lighting, watering, feeding, pest pressure, or mismatched plant selection.

These mixes are tools. Results vary based on how they are used.
