Fortify your crop's internal framework and build unshakeable structural resilience with Plagron Silic Rock. This professional-grade, high-performance additive delivers a highly bio-available form of silicon ( $SiO_2$ ) that acts as a structural shield for your plants.

By reinforcing individual cell walls from the inside out, Silic Rock produces significantly thicker stems and sturdier, rigid branches capable of supporting massive, heavy yields without bowing or snapping. Investing in early cell wall development accelerates overall growth rates, improves nutrient transport efficiency, and drastically heightens your plants' natural defences against environmental stressors, pests, and systemic diseases.

Core Cultivation Advantages:

Structural Cell Wall Reinforcement: Silicon integrates directly into the plant's cellular matrix. This structural reinforcement can produce stems up to twice as thick as those left untreated, providing the ultimate framework for heavy fruit and flower development.
Optimised Hydration & Drought Efficiency: By tightening and strengthening cellular barriers throughout the foliage, Silic Rock minimises unnecessary water transpiration, significantly reducing water loss and helping plants thrive during high-temperature spells.
Natural Shield Against Pests & Pathogens: The hardened plant tissue acts as a physical barrier. Sucking insects (like aphids or spider mites) and fungal spores (such as powdery mildew) find it incredibly difficult to pierce or penetrate the toughened outer cells.
Enhanced Nutrient Transport Channels: Thicker, more robust stalks feature expanded vascular systems. This allows the plant to efficiently absorb and transport water and vital macro-elements from the root zone up to the top canopy.

Application Timing & Dosing

Silic Rock is highly concentrated and should be run smoothly at a minimal dose throughout both the vegetative growth and flowering cycles:

Target Growth Phase	Recommended Dosage	Application Frequency
Vegetative Growth Phase	0.5ml to 1ml per 1 Litre of water	Add to your nutrient tank at every single feeding.
Full Flowering Phase	0.5ml to 1ml per 1 Litre of water	Add to your nutrient tank at every single feeding until flush.

⚠️ CRITICAL OPERATIONAL NOTE: Plagron Silic Rock is formulated exclusively for soil and coco coir mediums. It is not suitable for use in active hydroponic growing systems (such as DWC, NFT, or recirculating rockwool setups) as it may cause fluid instabilities.

Step-by-Step Usage Instructions:

1.Shake the bottle thoroughly:Agitation.

Before measuring out your daily dose, shake the Silic Rock container vigorously to ensure the silicon compounds are completely redistributed for an even concentration.

2.Add to your fresh water tank first:Silicon First Mixing.

Always add Silic Rock to your fresh water reservoir before your base nutrients. Dilute a maximum of 1ml per 1 Litre of water ( $1:1000$ ) and stir the water vigorously for 10 seconds.

3.Introduce your primary feeds:Base Integration.

Once the silicon is completely dissolved into the water, proceed to add your standard vegetative or flowering base nutrients (such as Terra or Alga) and stir thoroughly.

4.Check and adjust your values:pH Assessment.

Silicon naturally raises the alkalinity of water. Always use a calibrated digital meter to check your final liquid mix. Reduce the pH back down into your medium's sweet spot using Plagron Lemon Kick.
