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 TC substrate works ?

This substrate has been specifically formulated to meet the needs of Tissue culture plant and baby plants

Its composition provides a precise balance between drainage, aeration, and moisture retention, which is essential for healthy root development in tissue culture plant and baby plants, whether juvenile or well established.

Thanks to its airy yet stable structure, the roots benefit from excellent oxygenation while maintaining consistent and controlled moisture levels.

This effectively limits the risks of excess water, root rot, and fungal diseases, while supporting steady and long-term growth.

A substrate inspired by the natural habitat of tropical plants

This substrate is directly inspired by these natural conditions in order to recreate an environment close to their original habitat, while remaining perfectly suited for container cultivation.

Tissue culture plant and baby plant care recommendations

Water regularly to keep the substrate slightly moist, without ever allowing it to become waterlogged. Make sure no standing water remains at the bottom of the pot. A simple finger test helps ensure the substrate stays fresh between waterings.

tissue culture plant and baby plant thrive in bright indirect light, a humid atmosphere, and good air circulation, while being protected from cold drafts.

Regular but moderate fertilization, combined with a suitable substrate, promotes healthy foliage, strong vigor, and balanced growth.

How to use the tissue culture plant and baby plant substrate ?

Gently remove the agar from around the roots. Rinse the roots with lukewarm water to remove remaining residues and inspect them, trimming any damaged parts if necessary.

Place a layer of substrate at the bottom of the pot, position the plant in the center while ensuring the crown is not buried too deeply, then gradually fill in around the roots.

Lightly firm the substrate to stabilize the plant without compacting it, then water thoroughly to encourage healthy root establishment.
