Been using this stuff for a few years now and have had great results! I add it as a top dress to every new cycle then monthly when the garden is established and mix it in when making new batches of living soil.
No more mucking around with lime and rock dust.


STONE-AGE – Mineral Composite Plant Supplement
STONE-AGE is a 100% active organic mineral composite designed to deliver full-spectrum nutrition and soil regeneration without synthetic binders or fillers. Featuring rare volcanic and ancient mineral deposits, it provides a complete suite of plant-available calcium, magnesium, potassium, phosphorus, silica, sulphur, iron, and trace elements—complexed with raw Australian humic and fulvic compounds for optimal bioavailability. Unlike harsh synthetic boosters, STONE-AGE works synergistically with your soil biology, enhancing flower size, resin production, pest resistance, enzymatic function, and structural integrity while improving CEC, pH balance, and water retention.

What Is STONE-AGE?
STONE-AGE is a full-spectrum mineral amendment engineered for high-performance organic cultivation. It remediates mineral depletion, improves plant vigor, and supports a living, biologically resilient rhizosphere by supplying calcium, magnesium, potassium, phosphorus, sulphur, iron, silica, and a full suite of trace minerals—without resorting to synthetic chelators.
The carefully balanced ingredients are derived from geological and volcanic sources including Wollastonite, Montmorillonite, Leonardite, and natural shell-based limes. These are complexed with raw humic and fulvic acids to ensure bioavailability without interfering with soil life. Whether you're creating a new living soil, recharging an existing mix, or top-dressing plants in active growth, STONE-AGE provides a foundational mineral matrix to elevate plant health, flower quality, and microbial stability.
The Science Behind STONE-AGE
Sourced from volcanic flows, seabed sediment, and fossilized deposits, STONE-AGE includes Wollastonite, Leonardite, Azomite, Montmorillonite, Basalt, Sulphur, Shell Lime, and more—each selected for specific contributions to soil and plant performance.
High levels of bioavailable Silica enhance flower density, resistance to stress, and terpene/flavonoid synthesis. This supports increased trichome development, pest defense, and visual appeal.
Multiple forms of calcium and magnesium correct common deficiencies and buffer soil chemistry. These minerals promote enzyme activity, root integrity, and improved water/nutrient retention.
Naturally improves soil texture, porosity, and moisture-holding capacity. Humic and fulvic acids enhance microbial colonization, nutrient transport, and long-term soil vitality.
STONE-AGE is safe for use in all soil systems. It is slow-release by design, minimizing leaching and risk of burn. Works seamlessly with living soils and organic inputs.
How to Use STONE-AGE
Soil Building
- Use at up to 3.5% of total mix volume.
- For 50L of soil at 3%, apply 1.5L of STONE-AGE.
- Best combined with HERB-SUPERB at a 1:1 ratio for optimal biological and mineral balance. Mix thoroughly with moist materials and rest covered for 2+ weeks before planting.
Soil Recharging
- Apply at up to 2.5% of mix volume.
- For 50L at 2%, apply 1L STONE-AGE.
- Combine with HERB-SUPERB at a 2:1 ratio. Best results come with full incorporation and resting for microbial activation.
Planting Holes
- Incorporate at up to 2% into backfill soil.
- A generous adult handful per planting hole is ideal.
- Promotes early root establishment and balanced nutrition.
Top Dressing
- Small plants: 1 teaspoon per plant
- Medium plants: 1 tablespoon per plant
- Large plants: Up to 1 cup per plant
- Apply around the drip line, avoid direct contact with stem, water in thoroughly.
Compost Teas
- Add 0.5–1 teaspoon per 20L tea brew.
- Brew for 24 hours in oxygen-rich conditions.
- Enhances microbial mineral access and boosts soil activity when applied immediately.
- Use at up to 3.5% of total mix volume.

Frequently Asked Questions
What is STONE-AGE and what does it do?
STONE-AGE is a 100% active organic mineral blend that delivers complete nutrition, enhances soil structure, and supports plant health without synthetic chelates or harsh chemical binders.
How is STONE-AGE different from synthetic bloom boosters?
Unlike harsh PK boosters, STONE-AGE boosts phosphorus, potassium, calcium, and silica naturally—without harming microbes. It improves yield, resin, and structure while building soil fertility long-term.
Can STONE-AGE fix nutrient deficiencies?
Yes. It treats calcium, magnesium, and trace element deficiencies with balanced, plant-available minerals. It also enhances uptake through raw humic and fulvic complexes—no EDTA required.
Is STONE-AGE safe for living soil systems?
Absolutely. It’s fully compatible with living soils. STONE-AGE feeds microbes, improves pH and CEC, and works in harmony with your rhizosphere to regenerate and support healthy soil biology.
How do I use STONE-AGE—topdress or mix in?
You can do both. Topdress for ongoing support or mix into new or used soil blends. It also works well in compost teas or as part of a recharging mix.
What minerals are included in STONE-AGE?
It provides calcium, magnesium, potassium, phosphorus, silica, sulphur, iron, and full-spectrum trace minerals—sourced from volcanic, fossil, and rare mineral deposits for long-lasting plant and soil benefits.
