The Most Bioavailable Form of Silica—Engineered for Maximum Plant Performance

Not all silica supplements are equal. Pathway is a breakthrough in horticultural technology, delivering a unique 40% Mono Silicic Acid formula—the most bioavailable form of silicon available, supplying significantly higher amounts of plant-active silica than standard potassium silicate products.

Where conventional silica additives rely on potassium silicate (which must be converted by the plant before use), Pathway delivers mono silicic acid in a form plants can absorb and utilise immediately—at a fraction of the dose.

The go-to choice for growers searching for the best mono silicic acid supplement in Australia, a highly bioavailable silica for hydroponics, or a next-generation plant strengthener that outperforms standard silica products.

Why Mono Silicic Acid Outperforms Standard Silica

Silicon plays a critical role in plant health—but only in forms the plant can actually absorb. Mono silicic acid (Si(OH)₄) is the only form of silicon directly taken up by plant roots and translocated into tissue.

Immediate Bioavailability — No conversion required—plants absorb and utilise mono silicic acid directly, unlike potassium silicate which requires enzymatic breakdown first.
Higher Silica Deposition — More silicon reaches plant tissue, building stronger cell walls, thicker stems, and improved structural integrity.
Increased Pest & Disease Resistance — Silica deposited in epidermal cells creates a physical barrier against mites, insects, and fungal pathogens including powdery mildew.
Heat & Stress Tolerance — Improves plant resilience under high temperatures, intense lighting, and environmental stress—particularly relevant in Australian growing conditions.
Enhanced Nutrient Transport — Strengthens vascular tissue, improving the movement of water and nutrients throughout the plant.

Performance Benefits Across the Full Cycle

Stronger stems and branches capable of supporting heavier yields
Thicker, more resilient leaf structure
Improved resistance to pests, disease, and environmental stress
Better water use efficiency and drought tolerance
Increased yield potential through improved structural support

How to Use Pathway

Critical Mixing Order: Always add Pathway to water first, before adding any other nutrients or additives. This prevents precipitation and ensures full bioavailability.

Root Feed Dosage: 1ml per 10L of water

Frequency: At least once per week—can be used with every watering

Growth Stage: Suitable for all stages of vegetative and bloom growth. Cease use 7 days before harvest.

Foliar Application: Mix 2ml per 10L of water and spray during lights off or low lighting conditions. Apply once per week from early growth stages until the 4th week of flowering.

Compatible With: Hydroponics · Coco Coir · Soil

Perfect For

Growers wanting the most bioavailable silica supplement available
Hydroponic and coco growers seeking stronger plant structure without raising pH significantly
Indoor growers dealing with pest pressure, heat stress, or weak stems
Anyone searching for mono silicic acid in Australia, a bioavailable silica for hydroponics, or a next-generation alternative to potassium silicate

Frequently Asked Questions

How do I add Pathway 40% Mono Silicic Acid to my feeding program?

Add Pathway 40% Mono Silicic Acid to your nutrient solution after mixing your base nutrient. Always add additives to water rather than directly to concentrated nutrient solutions. Stir well after each addition and check EC and pH before use. Start at the lower end of the recommended dose range and increase progressively — additives are potent and more is not always better.

Is Pathway 40% Mono Silicic Acid compatible with organic and mineral nutrient programs?

Pathway 40% Mono Silicic Acid is compatible with most hydroponic nutrient programs including both mineral and organic-based systems. If running a fully organic or biological program, check the formulation — some mineral additives can inhibit beneficial microbial populations. When in doubt, contact us at hello@apexgrow.com.au for compatibility advice specific to your setup.

Can I use Pathway 40% Mono Silicic Acid in soil, coco, and hydro?

Yes — Pathway 40% Mono Silicic Acid is suitable for use across all growing mediums including soil, coco coir, perlite, rockwool, and all recirculating and run-to-waste hydroponic systems. Dose rates may vary slightly between growing systems — always follow the manufacturer's feeding chart for your specific medium.

Does Pathway 40% Mono Silicic Acid ship fast within Australia?

Yes — Pathway 40% Mono Silicic Acid ships from our Australian warehouse with fast tracked delivery Australia-wide. Most east coast orders arrive within 2–5 business days. WA, NT, and TAS orders typically arrive within 5–12 business days.
