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.

No Nutrients

This mix contains no added fertiliser.

When growing most houseplants on this, we would recommend our Tropical Slow Release Plant Food, which lasts for about 6 months.

Frequently Asked Questions

Is this mix natural?

Yes, the SYBAStones Base Mix is completely natural (not certified) as this mix contains no fertilisers.

How long do the fertilisers in the mix last?

This mix contains no added fertiliser. When growing most houseplants on this, we would recommend our Tropical Slow Release Plant Food, which lasts for about ~ 6 months.

How to use fertilisers for the basic SYBAStones mix?

Both hydroponics fertilisers as slow release osmocote fertilisers can be used with our SYBAStones mix. Our other SYBAStones Basic does not contain fertiliser so, be sure to add your prefered fertiliser!

Is this different from soil care?

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.

How to transplant from soil to SYBAStones?

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.

Which SYBASupport fertilisers do I use with SYBAStones?

Our slow-release fertilisers (not organic) are made for SYBAStones and other semi-hydro setups.

Is this for my plant?

  • Cactus & Succulent Mix – suitable for cacti and succulents
  • Orchid Mix – ideal for orchids
  • Houseplant Mix – great for aroids, Calatheas, Ficus, Alocasias, Marantas, Dieffenbachia, and more

How do I prepare the SYBAStones before use?

Rinse the mix before use. Some dust can form during transport, which is totally normal and easy to wash off.

Are the SYBAStones allergen free?

These mixes are allergen-free thanks to their stone-based composition.

I have mold growing in my pot with SYBAStones!

Noticed a smell or slimy texture after transplanting? A few things could be going on:

  • The roots were not fully cleaned
  • The mix is too wet
  • Some roots are dying from transplant shock

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.

What plant pots do I use?

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.
