About

Form. Function. Harmony.
Aquarium planters designed to elevate your plants, your tank, and your space.

At Mossari, we believe nature deserves a place at the heart of your home — not in isolation, but in elegant harmony. That’s why we created the Mossari Planter: a modern, self-watering vessel that bridges the worlds of houseplants and freshwater aquariums.

Each planter is a sculptural, functional expression of our core philosophy: simple materials, smart design, and a seamless connection between aquatic and botanical life.

How It Works

Mossari Planters use a passive wicking system to draw water from your aquarium directly to your plant’s roots — keeping them hydrated and healthy, with no guesswork or overwatering.

Our planters help support the health of your aquarium by allowing plants to absorb excess nutrients from the water, creating a balanced, low-maintenance ecosystem.

How It’s Made

Every Mossari product is 3D printed in small batches using PETG, a premium, water-resistant material chosen specifically for long-term exposure to moisture and humidity. Unlike PLA (commonly used in hobby printing), PETG offers superior durability and performance in aquatic environments.

Each piece is:

  • Precision-crafted with clean geometry and seamless fit

  • Designed to support modular customization (via extensions and brackets)

  • Assembled and checked by hand for quality and consistency

We use only plant-safe materials and pair each planter with a carefully selected soil or substrate blend to promote airflow, prevent rot, and encourage healthy growth.

Our Philosophy

We’re not a mass-produced plastics company. We’re a small studio with a passion for plants, aquariums, and meaningful design. Mossari is about reconnecting with nature in a way that feels intentional — functional beauty, inspired by the rhythms of water and growth.

Whether you’re a lifelong aquarist, a houseplant enthusiast, or someone discovering the joy of combining the two — Mossari is here to help you create living art in your space.
