Plagron Silic Rock 0,5l
Plagron Silic Rock 0.5L delivers plant-available silicon dioxide to strengthen cell walls, improve phosphorus and calcium absorption, and boost overall crop resilience. This mid-range 500 ml format is the preferred choice for regular growers seeking consistent silicon supplementation across multiple cultivation cycles. At a dosage of just 1 ml per litre of water applied at every watering, each bottle produces up to 500 litres of nutrient solution. The NPK formulation of 1.5-0-1.7 with 1.0% SiO₂ complements any existing feeding programme on soil and coco substrates without disrupting nutrient ratios.

Plagron Silic Rock 0.5L – Consistent Silicon Delivery for Optimised Crop Performance
Structural integrity is a performance variable that many growers underestimate. Plagron Silic Rock addresses this by providing a concentrated source of plant-available silicon dioxide (SiO₂) that integrates directly into cellular architecture. The 0.5L format is engineered for cultivators who run regular cycles and demand reliable nutrient supplementation without waste.
The Silicon Deficit in Modern Substrates
Most commercial growing media contain insufficient levels of bioavailable silicon for optimal plant development. Plants grown without adequate silicon produce thinner cell walls, weaker stems, and reduced structural capacity to support heavy flowering. Silic Rock resolves this deficit by delivering SiO₂ in an organic, root-absorbable form. The effects typically become visible within two to three weeks: stronger trunk development, more upright growth patterns, and visibly healthier foliage.
Dosage, pH Management, and Application
Shake the bottle thoroughly before every use. Apply a maximum of 1 ml per litre of water (1:1000 ratio) at each watering throughout the complete cultivation cycle – vegetative and flowering phases combined. The 0.5L format produces up to 500 litres of working solution. Critical note: Silic Rock has a product pH of 1.5, which will lower your solution pH. Always measure and adjust pH after adding Silic Rock and before introducing other nutrients. This product is not suitable for hydroponic systems (NFT, DWC, aeroponics) due to its organic composition. Flush irrigation lines after each session if using drip systems.
Measurable Impact on Plant Architecture
- Stem diameter increase: silicon deposition in cell walls produces measurably thicker stems, critical for supporting dense flower clusters during late bloom.
- Nutrient efficiency gains: silicon mobilises fixed phosphorus and calcium in the root zone, improving overall NPK utilisation rates.
- Stress resilience: thickened cell walls provide enhanced mechanical and thermal resistance, reducing crop losses from environmental fluctuations.
Building a Complete Plagron Stack
Silic Rock (NPK 1.5-0-1.7, SiO₂ 1.0%) operates as a structural supplement alongside your base feed. Combine it with Power Roots 0.5L during the vegetative phase for robust root networks, then add Sugar Royal 0.5L in bloom for enhanced resin and terpene output. For growers using coco, consider pairing with CalMag Pro 0.5L to ensure complete mineral coverage.

What is the pH of Plagron Silic Rock and how does it affect my nutrient solution?
Silic Rock has a very low product pH of 1.5, which will reduce the pH of your nutrient solution. Always measure pH after adding Silic Rock and adjust with pH up before introducing other products into the reservoir.
When should I start using Silic Rock 0.5L in my grow cycle?
Begin Silic Rock application once plants have developed their first true leaves. Continue use at every watering through both vegetative and flowering phases for progressive cell wall reinforcement throughout the entire growth cycle.
Is Silic Rock compatible with coco coir substrate?
Silic Rock is fully compatible with coco coir and soil-based substrates. It is only incompatible with recirculating hydroponic methods such as NFT, DWC, and aeroponics due to the potential for organic precipitate formation.
What volume of nutrient solution does the 0.5L bottle produce?
At the recommended maximum dosage of 1 ml per litre of water, each 0.5L bottle of Silic Rock produces up to 500 litres of nutrient solution – sufficient for multiple complete cultivation cycles in a mid-sized growing setup.
