Formulated and prepared in France 🇫🇷

The search for the ideal substrate is at the heart of our approach.

For more than two years, we tested and refined multiple formulations between Thailand and France under real growing conditions.

Drainage, aeration, water retention and root health were studied to create a mix suited to the needs of young plants and tissue culture plants.

The final formulation is completed in France. Each mix is then prepared, quality-checked and packed in our greenhouse near Paris.

🇫🇷 Formulated, prepared and quality-checked by our team in France.

Substrate for young & tissue culture plants

A mix designed for small plants, young specimens and plants freshly removed from tissue culture.

Its structure balances drainage, aeration and moisture retention to support developing roots without keeping the growing medium waterlogged.

1
Carefully remove the agar surrounding the roots.
2
Rinse the roots with lukewarm water and remove damaged areas if necessary.
3
Add substrate to the bottom of the pot and position the plant without burying the crown too deeply.
4
Fill around the roots and firm very lightly without compacting the mix.
5
Water evenly, then keep the substrate slightly moist but never waterlogged.

Young plants generally prefer bright indirect light, high humidity and good air circulation.

💧 The goal: consistent moisture while keeping plenty of air around developing roots.

Substrate composition

Each ingredient plays a specific role in balancing aeration, moisture and drainage.

50%
Fine maritime pine bark
Provides a breathable structure and supports oxygenation around developing roots.
35%
Perlite
Keeps the mix light, improves aeration and strongly reduces compaction.
10%
Hydroponic clay pebbles
Stabilise the structure and help maintain even air and moisture circulation.
5%
Horticultural biochar
Adds complementary porosity and helps maintain a stable rooting environment.
🌱 A very airy, lightweight mix designed to retain useful moisture without suffocating developing root systems.

WHAT THEY THINK

We changed their substrate. Apparently, their roots had a few things to say.

M

Monstera

★★★★★ roots finally breathing

Finally, a substrate with enough air. My roots had almost forgotten what breathing felt like.

A

Alocasia

★★★★★ demanding but satisfied

Moist, but not waterlogged. Airy, but not dry. Finally, someone read my requirements.

Anthurium

★★★★★ root connoisseur

Drainage, moisture, oxygen… my aerial roots are asking if they can move in too.

P

Philodendron

★★★★★ ready to climb

A coarse substrate, plenty of air around the roots… great, now give me a two-metre pole.

H

Homalomena

★★★★★ moisture approved

It stays fresh without turning into a swimming pool. I really wasn't asking for much.

★★★★★ fresh out of tissue culture

Yesterday I was in a flask. Today I have my own pot. Life moves fast.

FAQ

Would the Tissue Culture substrate be suitable for my plant?

This substrate is directly inspired by these natural conditions in order to recreate an environment similar to their original habitat, while remaining perfectly adapted to pot cultivation and healthy, sustainable long-term growth.

When should I repot my plant?

  • Roots growing out of the bottom of the pot
  • A substrate that dries out very quickly between waterings
  • A plant that has become too heavy or unstable, and tends to tip over
  • Roots that push the plant upwards and out of the pot
  • Repotting is recommended every 1 to 2 years , depending on the plant's growth.

How long can the substrate be stored?

A sealed substrate , stored in its original bag, dry and away from light, can be kept for 12 to 18 months while preserving its physical and biological properties. Once opened , the substrate remains fully usable for 6 to 9 months , provided it is properly resealed and stored in a dry environment.

A used substrate (already potted and watered) remains effective for 9 to 18 months , depending on the plant, watering frequency, and growing conditions. Beyond this period, the structure and biological activity gradually decrease; it is then recommended to repot or renew the substrate every 1 to 2 years to maintain an optimal root environment. 🌿

How much Tissue Culture substrate do I need?

Use the jar volume calculator available on the product page to determine the quantity you need.

What should I do if my plant doesn't seem happier with its new substrate?

If your plant doesn't seem to be thriving in this substrate, please don't hesitate to contact us . We'll help you diagnose the situation (substrate, watering, light, environment) and find the best solution to ensure healthy and sustainable growth for your plant 🌿
