Sybastones Base Mix (Unfertilised) Is the Soilless Mix for Adventurous Plant Lovers

Take your houseplant care to the next level with SYBAStones Base Mix (Unfertilised), a mineral-based, soilless mix built for quicker root development, cleaner plant care, and zero pest problems. Whether you’re growing Alocasias, Philodendrons, or just want an upgrade from basic potting soil, this substrate gives your plants the structure, airflow, and hydration control they need to thrive—no fungus gnats, no breakdown, no mess.

Perfect for most houseplants, this mix is unfertilised, so you stay fully in control of feeding. Pair it with one of our slow-release fertilisers or your go-to mineral-based liquid feed for a custom setup that grows with your collection.

Why Switch to a Soilless Mix?

Traditional potting soil breaks down, compacts, and attracts pests. This all-mineral, peat-free mix doesn’t. With ingredients like pumice, zeolite, and lava rock, SYBAStones Base Mix (Unfertilised) holds its structure for years and stays free from fungus gnats, root lice, and mould.

  • 100% no fungus gnats—guaranteed
  • Reusable for years, just rinse and refresh
  • Perfect for transparent pots without drainage holes (yes, really!)
  • Soilless and compost-free, with no organic matter to degrade

Watering becomes easier and more predictable. Especially when paired with a self-watering pot, the mix delivers perfect moisture regulation while staying breathable and light around the roots.

Designed for Quick Root Development and Less Care

Thanks to its chunky grain size (4–8 mm), this mix supports healthy root oxygenation and strong growth while keeping the water-to-air ratio balanced. It suits most houseplants—big or small—and is especially great for those who love to tinker, tweak, and improve their care routine.

Each mineral serves a purpose:

  • Pumice adds lift and keeps the mix ultra-aerated
  • Zeolite stores and releases nutrients and moisture as needed
  • Lava rock adds weight and stability, anchoring roots and supplying trace minerals

All together, they form a breathable, long-lasting potting mix base that works with your routine—not against it.

Customisable Care With Your Choice of Fertiliser

Because this mix contains no added nutrients, you get complete control over plant nutrition. Use it with:

  • Sybotanica’s slow-release fertiliser range for a low-maintenance solution
  • A mineral-based liquid fertiliser for hands-on plant care

This flexibility makes it the perfect canvas for experienced and curious plant parents who know their plants—and want to keep them thriving long-term.

For the Adventurous Plant Lover

SYBAStones Base Mix (Unfertilised) isn’t just a soil replacement—it’s a smarter growing system for the indoor houseplant enthusiast ready to go beyond standard care. Want quicker root growth? Easier watering? No pest problems? A substrate that stays light and airy, even years down the line?

This is it.

You can use it in decorative transparent pots with no holes, self-watering containers, or anything in between. No compaction, no rot, no hassle. Just clean, sustainable, plant-forward design.

Sybotanica Makes Substrates Smarter

Sybotanica developed the SYBAStones series to solve common frustrations: soggy soil, gnat infestations, nutrient guessing, and endless repotting. This mix reflects years of experimentation and refinement by real plant lovers who wanted better tools—not just another bag of dirt.

This isn’t for everyone. But if you’re ready to grow smarter, SYBAStones Base Mix (Unfertilised) is your new standard.

Fair Production - Handmade in our social workplace

At Sybotanica we not only want to make plants happy, but people happy as well. In our production team we exclusively hire people with a distance from the workforce, and help them rehabilitate to the normal working life.

Take Peter for example:

Peter has been with Sybotanica since the 1st hour, and has now been promoted to head of production & a permanent contract! Where he was the first employee, he now manages a team of 3 production workers.

What makes this achievement even more impressive is that Peter achieved all this with only 10% visibility! 🕶️ With a few minor adjustments to his working environment, Peter is able to perform his job 100%.

Peter has now been through two moves and knows all the ins & outs of Sybotanica. He can even feel by the potting soil which variety it is. That's quite a challenge with 16 different mixes!

We are confident that Peter will keep production running smoothly in the coming years too! 💪

Customer video review of Fine Houseplant Mineral Mix

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.

Fine Houseplant Mineral Mix

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:)

Customer video review of Cacti & Succulent Mineral Mix

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.

Customer video review of Fine Houseplant Mineral Mix

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. 😊😊

Zeker een aanrader voor o.a. alocasia. Mijn planten hebben stabiele groei sinds ik ze in semi-hydro heb staan en de steentjes zien er ook nog eens mooi uit. Ik ben er blij mee!

Base Mineral Mix (SYBA-Hydro, Unfertilised)

Customer video review of Fine Houseplant Mineral Mix

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.

Fine Houseplant Mineral Mix

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

Fine Houseplant Mineral Mix

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.
