Ingredient architecture of Rainbows & Unicorns Aroid Potting Mix.

Structural Components in This Aroid Substrate

Chunky Coco Coir

Creates the primary structure of the mix, forming air channels that prevent compaction while retaining usable moisture.

Coco Pith

Balances hydration levels and buffers fluctuations in indoor watering cycles.

Perlite

Increases air-filled porosity and improves drainage performance.

Diatomaceous Earth

Enhances drainage and contributes silica within the soil matrix.

Biological & Organic Inputs

Worm Castings

Provide natural slow-release nutrients and improve substrate structure.

Compost

Supports microbial diversity and nutrient cycling.

Microbial Root Enhancer

Includes mycorrhizae, beneficial bacteria, and trichoderma to assist nutrient absorption.

Humic Acids

Improve nutrient availability and microbial interaction at the root zone.

Mineral & Nutrient Support

Azomite

Supplies trace minerals that maintain balanced nutrient availability.

6-2-4 Fertilizer

Provides steady macronutrient support for foliage and root development.

Rooting Supplements

Encourage strong root establishment during planting and repotting.

Why Ingredient Structure Matters for Aroids

Aroids require consistent oxygen at the root zone. Dense, fine soils restrict airflow. A structured chunky substrate maintains drainage channels while delivering biological and mineral support.
