Mossari Inert Wicking Substrate – Self-Watering Planter Soil

6 Cups | Fertilizer-Free Soil for Self-Watering & Aquarium Planters

Engineered specifically for self-watering planters and aquarium-mounted systems, this 6-cup inert wicking substrate contains no added fertilizers or amendments. Plants receive moisture and nutrients entirely from the water source below.

This is the clean, controlled option for aquarium-fed growing.

Built for Wicking Performance

Self-watering systems require structure, aeration, and consistent moisture distribution. Traditional potting soils often compact or stay overly saturated at the base.

This blend is designed for continuous moisture environments and steady capillary action.

Includes:

• Coco coir for balanced moisture retention
• Coco chips for long-term aeration and structure
• Perlite for drainage and oxygen flow

The result is an evenly hydrated root zone that maintains airflow and resists compaction over time.

When to Choose the Inert Blend

Ideal for:

• Established aquariums with stable nitrate levels
• Growers who prefer full nutrient control
• Aquarium-fed plant systems
• Fertilizer-free setups

Plants rely entirely on nutrients drawn from aquarium water, creating a simple and predictable growing method.

Aquarium-Compatible

In Mossari aquarium-mounted planters, water moves upward through capillary action rather than flowing downward through the soil. This controlled movement supports stable root moisture while allowing plants to absorb nutrients from tank water.

One 6-cup bag fills:
