Rhino Skin 5L – Potassium Silicate Strength Additive by Advanced Nutrients

Reinforce Plant Structure With a Reliable Silica Source

Rhino Skin 5L is a potassium silicate–based additive formulated to strengthen plant cell walls and improve structural resilience throughout the vegetative and flowering stages. Silica is not naturally abundant in hydroponic solutions or refined substrates such as coco, so Rhino Skin provides a stable and plant-available source to help support thicker stems, improved rigidity, and better overall plant tolerance to environmental stress.

Unlike raw silica products that can be difficult to dissolve or cause pH instability, Rhino Skin is engineered to blend cleanly with nutrient solutions and remain stable within hydroponic systems. This makes it suitable for growers seeking a straightforward, dependable silica supplement.

Key Features:

• Volume: 5L – suitable for medium to large-scale gardens

• Silica Source: Potassium silicate – supports stronger stems and cell walls

• Increases Structural Strength: Helps plants support heavier flowers

• Supports Environmental Resilience: Silica contributes to improved tolerance to physical stress

• System-Friendly: Mixes cleanly in hydroponic reservoirs and coco/soil feeds

• Usage Window: Can be used in vegetative and flowering stages

• 1 × 5L bottle of Advanced Nutrients Rhino Skin

• Secure tamper-evident cap

• Label with full mixing instructions and safety information

How to Use the Product & Best Usage Recommendations:

Dosage:

• Add 2 ml per litre of water

• Use throughout the vegetative stage and continue into early and mid-flowering

• Discontinue during the final week or two of bloom if you are performing a flush

Mixing Instructions:

• Shake the bottle well before use

• Add Rhino Skin to your reservoir after base nutrients

• Ensure good circulation for even distribution

• Compatible with all Advanced Nutrients base nutrients and supplements

Growing System Compatibility:

• Hydroponics (DWC, recirculating, NFT, RDWC) – stable in solution and non-clogging

• Coco coir – helps compensate for coco’s naturally low silica content

• Soil – supports stronger stems and improved structural development

Best Usage Recommendations:

• Use Rhino Skin continuously during veg for the best structural foundation

• Combine with strong lighting and good airflow to encourage thicker stems naturally

• Avoid mixing concentrated silica with highly acidic inputs—always dilute into water first

• Maintain stable pH when adding Rhino Skin, especially in hydroponics

• Stronger stems help support heavier flowers later—using Rhino Skin early optimises this benefit

Rhino Skin is ideal for growers who want reliable stem strength, better structure, and increased plant stability, especially in high-yield or high-intensity lighting setups.
