Formulated and prepared in France 🇫🇷
A versatile substrate developed for most indoor plants.
For more than two years, we tested and refined different formulations between Thailand and France under real growing conditions.
Our goal: create an easy-to-use mix with a balanced combination of moisture retention, aeration, drainage and structural stability.
The high proportion of buffered coco coir helps maintain consistent moisture, while perlite, two grades of pine bark, coconut chips, clay pebbles and biochar provide structure and root aeration.
Each mix is then prepared, quality-checked and packed in our greenhouse near Paris.

How to use the indoor plant substrate
A versatile mix designed to simplify repotting while providing roots with a balanced growing environment.
It combines good moisture retention with enough aeration to prevent a dense growing medium from remaining constantly waterlogged.
For future watering, generally allow the surface to begin drying before watering again. Frequency should always be adjusted to the plant, season, light, temperature and pot size.
Indoor plant substrate composition
A versatile formula combining moisture retention, porosity and structural components in different particle sizes.
Forms the base of the mix and helps maintain consistent moisture while keeping the substrate light.
Increases porosity, keeps the mix light and reduces compaction around the roots.
Stabilise the structure and support even air and water circulation.
Provides finer structure around the root zone and improves aeration throughout the mix.
Creates larger air spaces and provides long-lasting structure to the substrate.
Complement the structure of the mix and create additional spaces between the different ingredients.
Its porous structure complements the mix and helps maintain a stable rooting environment.
WHAT THEY THINK
We changed their substrate. Apparently, their roots had a few things to say.
Monstera
Finally, a substrate with enough air. My roots had almost forgotten what breathing felt like.
Alocasia
Moist, but not waterlogged. Airy, but not dry. Finally, someone read my requirements.
Anthurium
Drainage, moisture, oxygen… my aerial roots are asking if they can move in too.
Philodendron
A coarse substrate, plenty of air around the roots… great, now give me a two-metre pole.
Homalomena
It stays fresh without turning into a swimming pool. I really wasn't asking for much.
Baby Plant
Yesterday I was in a flask. Today I have my own pot. Life moves fast.

FAQ
Would the Indoor Plant substrate be suitable for my plant?
Most houseplants originate from tropical or subtropical environments, where the soils are rich in organic matter, well-aerated, and constantly draining. This substrate is inspired by these natural conditions to recreate an environment close to their original habitat, while remaining perfectly suited to pot cultivation.
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 indoor plant 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?
