The expert in soil
Say goodbye to soggy soil, fungus gnats, and compacted roots. SYBAStones Houseplant Mineral Mix is a peat-free, soilless substrate developed for strong root growth, stable moisture, and long-lasting structure—no breakdown, no pests, no stress. With 180 days of slow-release tropical fertiliser already mixed in, it’s the easiest upgrade for lush, thriving foliage.
Built on a base of lava rock, pumice, and zeolite, this mix supports everything from leafy aroids and upright Calatheas to trailing Pothos and Monstera cuttings. Whether you’re repotting your favourite tropicals or starting fresh with a self-watering setup, this mineral mix delivers the support your plants need to grow stronger and stay pest-free.
SYBAStones Houseplant Mineral Mix comes in two grain sizes so you can match it to your plant’s root system and watering style:
Both versions provide excellent drainage and oxygenation while holding on to just enough moisture to keep roots active and healthy.
Traditional potting soil breaks down and compacts, creating the perfect conditions for root rot and fungus gnats. SYBAStones Houseplant Mineral Mix is 100% organic-free, meaning no decaying matter, no mould, and zero fungus gnats—guaranteed.
This is the future of plant care: mineral-based, smartly structured, and made to last.
Every component in this mix supports long-term growth and healthier roots:
Together, these ingredients form a stable, airy environment that keeps your plant hydrated—but never waterlogged.
This mix includes a balanced, plant-safe slow-release fertiliser specifically formulated for tropical houseplants. That means no feeding for the first 180 days—your plants get all the nutrients they need with no extra effort. After that, top up with:
This is clean, low-maintenance indoor gardening at its best.
SYBAStones Houseplant Mineral Mix isn’t just an alternative to potting soil—it’s a smarter foundation for growing. No compaction. No decay. Just structure, airflow, and nutrient support that actually lasts.
Use it in self-watering pots, transparent pots without drainage holes, or even hanging planters. Your plants stay grounded, the roots stay happy, and you stay in control.

If the pot is differently shaped (Square, oval, e.t.c.), the calculations might not be accurate. You can also check out the plant pots product pages to check their total volume.

With soilless mixes there is no chance of soil-borne pests, such as fungus gnats, root lice or mould.
Since this mix is based on stones, there is no degrading soil or compaction risk. Making these stones endlessly reusable.
In combination with a selfwatering pot, this makes plant care and watering easier for you! Easily check the water level of the waterreservoir. And no more worries about over or underwatering your plants!
Both hydroponics fertilisers and slow-release osmocote fertilisers can be used with our SYBAStones mix.
Our SYBAStones Houseplant already contains fertiliser for up to 6 months, so no extra fertiliser is needed until after 6 months of using the mix.
Yes, the SYBAStones Houseplant mix itself is natural. However, the slow-release fertilisers are not. To ensure these fertilisers are of high quality and release nutrients slowly, it is not possible to produce them naturally.
Our Tropical Slow-Release Plant Food, which is added to this mix, lasts for ~6 months.
Both hydroponics fertilisers and slow-release osmocote fertilisers can be used with our SYBAStones mix.
Our other SYBAStones Houseplant already contains fertiliser for up to 6 months, so no extra fertiliser is needed until after 6 months of using the mix.
Yes, growing in SYBAStones works a bit differently from using regular soil. Watering, fertilising, and transplanting all follow new rules.
It’s a great method, but not every plant is a fan. Always check if your plant is suited for semi-hydro. More info below.
Got a cutting grown in water? You can plant it directly into SYBAStones. For soil-grown plants, it's best to remove all old soil before transplanting, especially if you've had fungus gnat issues. Clean roots are key.
Our slow-release fertilisers (not organic) are made for SYBAStones and other semi-hydro setups.
Rinse the mix before use. Some dust can form during transport, which is totally normal and easy to wash off.
These mixes are allergen-free thanks to their stone-based composition.
Noticed a smell or slimy texture after transplanting? A few things could be going on:
If you're sure the roots were clean or you're using a water cutting, the issue might be from dead plant material. Flush the pot thoroughly to rinse it out.
If the problem continues, inspect the roots. Some plants don't adapt well to mineral substrates and might not make the switch.
We recommend to use a self-watering plant pot!
You can use a water reservoir pot with your SYBAStones to create a semi hydroponics set up.
Most plants that love moist soils will appreciate this, such as aroids, calatheas, marantha, ficus, dieffenbachia, anthuriums and alocasias.
However for cacti & succulents, and other plants preferring dry soils, this is not recommended as these plants do not appreciate having moist roots all the time. Use a regular pot with drainage holes.

Heel erg blij mee. Ik ben al mijn zelf gestekte planten op de steentjes aan het zetten. Zowel de wortelgroei als bladgroei worden hartstikke goed gestimuleerd. Daarnaast vind ik het een stuk makkelijker qua water geven. Je ziet in een oogopslag of het aangevuld moet worden.

Store owner replied: Bonjour Christine, Merci pour ton avis. Le mélange minéral reste sec en surface. J’aimerais bien examiner avec toi pourquoi le fond est trop humide. Dans quel pot as-tu mis tes orchidées ? Je te demanderais de nous envoyer un e-mail afin que nous puissions déterminer ensemble pourquoi le fond est trop humide.

Ein wenig großstückigeres Substrat als eine bekannte Marke deren Substrat bisher von mir verwendet wurde, was durch die größeren Stückchen für mehr Belüftung der Wurzeln sorgen dürfte. Sieht qualitativ hochwertig aus, ob meine Pflanzen der gleichen Meinung sind und sich wohl fühlen, wird sich über die Zeit zeigen :)

Hatte viele Schwierigkeiten mit Trauermücken, trotz umtopfen, Wurzen abwaschen, teure Erde gekauft... Bin auf das Mineral Substrat von SYBotanica gestoßen und total begeistert. Sieht nicht nur hübsch aus, sondern ist auch super praktisch und meine Pflanzen mögen es und keine Schwierigkeiten mehr mit Fliegen:)

I transferred my poinsettia into the mineral mix and pruned it shortly after, and after a short transition period where it looked a bit droopy, it seems to be really thriving now! My succulent leaf propagations are also doing really well in it and have lots of strong roots.
Elisabeth 5/5
I received an import plant with almost just an aerial roots. I decided to put it on chuncky mineral mix from Sybotanica and Let it sit on a self watering pot. I must say it does what it promise from their website. It is a game changer!!! As you can see on the video it has healthy roots and soon it needs a repotting! If you havent tried it, I recommend you start doing it and you will not regret. 😊😊

I received the plant with almost only aerial roots and I decided to put it on chuncky mineral mix from Sybotanica and have it in a self watering pot and jupiiii now plants has healthy roots and soon need a repotting.

Claire S. 5/5
Insgesamt bin ich mit den Sybastones sehr zufrieden, meine Monstera variegata hat sich sehr schnell an sie gewöhnt und nach dem Umtopfen keine Anzeichen von Stress gezeigt. Die einzige Kritik die ich habe ist, dass die Steine relativ schwer sind. Ich habe Pflanzen die in einem ähnlichen Substrat stehen deren Töpfe deutlich leichter sind, ich werde deshalb beim nächsten eintopfen etwas Blähton untermischen, um die gesamte Mischung etwas leichter zu machen.

Substrat très sale, pas évident de rincer 5L avant usage. Granulométrie intéressante pour maintenir les grosses plantes lourdes (chunky).
Sandra T. 3/5
Store owner replied: Bonjour Sandra, Merci pour ton avis. C'est vrai que le rinçage demande pas mal de travail. Malheureusement, d'un point de vue logistique, il n'est pas possible de livrer le produit déjà propre. De plus, il est important de bien le laver juste avant utilisation. N'hésite pas à nous envoyer un e-mail si tu as d'autres questions, nous serons ravis de t'aider. Femke de Sybotanica
Substrat minéral très très sale, contrairement aux avis que j'avais lus. Fine ou chunky, c'est la même chose. 4 sacs à nettoyer avant usage, vraiment pas pratique... Dommage car granulométrie intéressante.
Sandra T. 3/5
Store owner replied: Bonjour Sandra, Merci pour ton avis. Nos mélanges minéraux peuvent en effet être un peu poussiéreux, car de la poussière se forme pendant le transport. C'est pourquoi nous recommandons de rincer le mélange avant utilisation. Nous expédions les mélanges minéraux légèrement humides afin d'éviter une formation excessive de poussière, mais malheureusement, cela peut tout de même arriver, et l'éliminer peut demander un peu de travail. Je suis désolée d'apprendre que les granulés sont plus gros que ce à quoi vous vous attendiez. Avec une granulométrie de 4 à 8 mm, notre mélange minéral Fine Houseplant possède l'une des plus petites granules de notre gamme et convient aux racines et aux plantes de petite taille.
