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 indoor plant substrate works

This substrate has been designed to meet the needs of most indoor plants, from the most common to the most demanding. Its formulation promotes an optimal balance between drainage, aeration, and water retention, allowing roots to develop in a healthy and stable environment.

Carefully selected components ensure proper air circulation around the roots while maintaining controlled moisture levels. This structure helps reduce the risk of excess water, root rot, and fungal diseases, while supporting active and long-lasting growth.

A substrate inspired by the natural habitat of indoor plants

Most indoor plants originate from tropical or subtropical environments, where soils are rich in organic matter, well-aerated, and consistently free-draining. This substrate is inspired by these natural conditions to recreate an environment close to their original habitat, while remaining perfectly suited for container growing.

Indoor plant care tips

Water moderately and allow the surface of the substrate to dry slightly between waterings. A simple finger test helps determine the moisture level. Most indoor plants prefer a slightly humid atmosphere and bright, indirect light.
Reasonable and regular fertilization, combined with a high-quality substrate, helps maintain balanced, resilient, and healthy plants.

How to use the indoor plant substrate

Using this substrate is simple and effective. Start by gently removing as much of the old substrate as possible from around the roots. To make removal easier, lightly squeeze the pot from the sides to release the plant. Then rinse the roots under lukewarm water to remove any remaining residue.
Take this opportunity to remove any damaged or dry leaves using clean scissors. Your plant is now ready to be repotted. Add a thin layer of substrate to the bottom of the pot, then place the plant in the center.
Gradually add substrate around the sides, ensuring that the base of the plant is just covered. Gently firm the substrate to stabilize the roots without excessive compaction. Water thoroughly after repotting to help the substrate settle and promote strong root establishment.
