Grow tropical houseplants directly from your aquarium with this large self-watering wicking planter designed to fit both rimmed and rimless tanks.

Made from aquarium-safe materials, the Mossari Large Wicking Pot mounts securely to your tank and uses passive capillary action to draw water from the aquarium into the root zone above. No pumps. No plumbing. No daily watering.

Your aquarium becomes the irrigation system.

How the Aquarium Wicking System Works

A wick extends from the planter into your aquarium water. As the plant uses moisture, water is continuously drawn upward and distributed evenly throughout the substrate.

This creates a stable, consistently moist root zone that avoids the extreme wet-dry cycle of traditional watering. Many tropical houseplants thrive in this steady moisture environment.

Ferns, trailing vines, compact foliage plants, creeping species, and other humidity-loving tropical plants adapt especially well to this system.

Substrate Options – Choose Your Growing Strategy

Customize your planter with one of two wicking substrate blends, depending on how you want your aquarium system to perform.

Enriched Wicking Blend – Added Nutrient Support

Designed for stronger early growth and root development (happy roots, happy plants).

Includes:
• Coco coir, perlite
• Worm castings
• Kelp meal
• Neem meal
• Gypsum

Why upgrade to Enriched?

Worm castings provide gentle, plant-available nutrients and beneficial microbial activity that support root health.

Kelp meal supplies trace minerals and natural growth compounds that encourage fuller foliage and stronger development.

Neem meal contributes organic matter and supports a balanced root-zone environment.

Gypsum provides calcium for structural support and helps maintain substrate structure without dramatically affecting pH.

This option works especially well for lightly stocked aquariums, newer tanks, or growers who want more vigorous above-tank growth.

When used properly in a Mossari wicking system, amendments remain primarily concentrated in the root zone rather than freely washing into the aquarium.

Inert Wicking Blend – Aquarium-Fed Only

Designed for fully aquarium-driven nutrient systems.

Includes:
• Coco coir
• Coco chips
• Perlite

No added fertilizers or amendments.

Plants rely entirely on nutrients drawn from aquarium water. Ideal for established tanks with steady nitrate production or growers who prefer complete nutrient control.

Designed for Plant and Fish Health

The wicking system separates the plant root zone from direct water flow. Water moves upward through capillary action rather than pouring through the substrate.

This helps:

• Maintain stable root moisture
• Avoid heavy nutrient dumping into the aquarium
• Allow plants to assist in nutrient uptake from tank water
