Houseplant Mineral Mix

SYBAStones Houseplant Mineral Mix Is the Cleanest Way to Grow Happy, Healthy Plants

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.

Fine or Chunky? You Choose the Structure

SYBAStones Houseplant Mineral Mix comes in two grain sizes so you can match it to your plant’s root system and watering style:

• Fine (4–8 mm): Ideal for medium-rooted plants like Calatheas, Philodendrons, Marantas, and Anthuriums that enjoy consistent airflow but also need gentle moisture control.
• Chunky (8–16 mm): Perfect for large aroids, mature houseplants, and plants that prefer to dry out a bit more between watering. Chunky grains keep the substrate extra open and reduce the chance of overwatering.

Both versions provide excellent drainage and oxygenation while holding on to just enough moisture to keep roots active and healthy.

Soilless, Pest-Free, and Endlessly Reusable

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.

• Pre-fertilised with 180 days of slow-release tropical nutrients
• Perfect for use in self-watering or (transparent) drainage-free pots
• Ultra-breathable and moisture-stable
• No organic matter = no decay, no pests, no mess
• Fully reusable—just rinse between uses

This is the future of plant care: mineral-based, smartly structured, and made to last.

Each Mineral Plays a Role in Plant Health

Every component in this mix supports long-term growth and healthier roots:

• Lava rock: Anchors the plant while providing trace minerals and weight
• Pumice: Improves airflow and drainage, keeping the mix light
• Zeolite: Naturally absorbs and releases nutrients and moisture as needed
• Tropical slow-release fertiliser: Feeds your plant steadily over 180 days

Together, these ingredients form a stable, airy environment that keeps your plant hydrated—but never waterlogged.

Just Pot It and Forget It (For Six Months)

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:

• Sybotanica’s slow-release fertiliser range, designed to support your plants through every season

This is clean, low-maintenance indoor gardening at its best.
