6 Cups | Nutrient-Amended Soil for Self-Watering & Aquarium Planters

Engineered specifically for self-watering planters and aquarium-mounted systems, this 6-cup enriched wicking substrate provides structured aeration with added root-zone nutrient support.

Enriched with:

• Worm castings 
• Kelp meal
• Neem meal
• Gypsum

Unlike standard potting soil, this blend is designed for continuous moisture environments where water is drawn upward through capillary action rather than poured from above.

This is the performance-focused option for growers who want stronger establishment and more vigorous foliage growth.

Built for Wicking Performance

Self-watering systems require the right balance of moisture retention and airflow. Traditional potting soils often compact or remain overly saturated at the base.

This blend is structured for steady capillary action and long-term stability.

Includes:

• Coco coir for balanced moisture retention
• Perlite for drainage and oxygen flow

The result is an evenly hydrated root zone that maintains airflow while supporting consistent moisture.

Why Choose the Enriched Blend

In addition to structural performance, this blend includes naturally sourced biological and mineral amendments that support root development.

• Worm castings provide gentle plant-available nutrients and microbial activity
• Kelp meal supplies trace minerals and natural growth compounds
• Neem meal contributes organic matter and supports a balanced root environment
• Gypsum provides calcium and helps maintain substrate structure

This added nutrient buffering is especially helpful for:

• Lightly stocked aquariums
• New tanks building nutrient levels
• Early plant establishment
• Growers who want fuller, faster above-tank growth

Aquarium-Compatible

In Mossari aquarium-mounted planters, water moves upward through capillary action rather than flowing downward through the soil. This controlled movement helps keep amendments concentrated in the root zone while allowing plants to draw moisture from aquarium water.

How Much Does 6 Cups Fill?

One 6-cup bag fills:

• One Large Aquarium-Mounted Wicking Pot
