The search for the perfect substrate is at the core of our philosophy. Over more than two years, we researched, tested, and refined multiple formulations to create substrates tailored to the specific needs of each plant. This in-depth work was carried out between Thailand and France, under real growing conditions, with extensive testing focused on drainage, aeration, water retention, and root health. The final formulation of our substrates is completed in France. All our substrates are then prepared and packaged in our greenhouse in the Paris region, under strict quality control, ensuring reliable, high-performance, and long-lasting growing media.

How our base substrate works

This substrate has been specifically formulated to be used as an active drainage layer, placed at the bottom of the pot and representing approximately 10 to 20% of the total pot volume.

Its composition provides a precise balance between drainage, aeration, and moisture management, which is essential to protect the root systems of all indoor plants, including the most sensitive ones.

Thanks to its stable and highly aerated structure, excess water is quickly evacuated while air circulates freely at the base of the pot.

This effectively reduces the risks of standing water, root rot, and fungal imbalance, while creating a healthy and long-lasting root environment.

An active drainage layer inspired by natural conditions

In their natural habitats, many plants grow in stratified soils where water drains naturally and roots benefit from excellent oxygenation.

This base substrate is inspired by those conditions to recreate, at the bottom of the pot, a draining, aerated, and biologically balanced environment perfectly suited for container cultivation.

How to use the base substrate

Place a layer of the base substrate representing approximately 10 to 20% of the pot height. Then add your main growing substrate on top and install the plant.

This active drainage layer helps secure watering, improves substrate longevity, and promotes healthy root development over the long term.
