Plagron Silic Rock 0,25l
Plagron Silic Rock 0.25L is a liquid silicon fertilizer engineered to address one of the most overlooked deficiencies in indoor cultivation. Silicon strengthens cell walls, enhances phosphorus and calcium uptake, and increases overall plant resilience against environmental stress. This 250 ml trial format delivers up to 250 litres of nutrient solution at a maximum dosage of 1 ml per litre of water. Apply at every watering throughout the entire growth cycle on soil and coco substrates. With an NPK ratio of 1.5-0-1.7 and 1.0% SiO₂, Silic Rock integrates seamlessly into any Plagron feeding schedule. Explore the structural benefits of silicon supplementation with this compact starter size.
Plagron Silic Rock 0.25L – Silicon Supplementation for Structural Plant Integrity
Silicon deficiency remains one of the most underdiagnosed issues in indoor growing. While most cultivators optimise nitrogen, phosphorus, and potassium levels, silicon – a critical structural element – is often absent from standard feeding programmes. Plagron Silic Rock delivers bioavailable silicon dioxide in a concentrated liquid format. This 0.25L bottle is the ideal entry point for growers evaluating silicon supplementation.
Mechanism of Action
Silicon dioxide (SiO₂) from Silic Rock is absorbed through the root system and deposited in plant cell walls as biogenic silica. This process physically thickens and hardens cell structures, resulting in measurably stronger stems and more rigid foliage. Beyond structural reinforcement, silicon acts as a nutrient mobiliser: it increases the bioavailability of phosphorus, calcium, and trace elements in the root zone, effectively improving the efficiency of your existing nutrient programme.
Key Performance Benefits
- Enhanced cell wall rigidity: silicon-fortified plants develop thicker stems and branches capable of supporting heavier flower clusters without mechanical support.
- Improved nutrient uptake: silicon mobilises less available forms of phosphorus and calcium in the substrate, reducing secondary deficiencies.
- Increased stress tolerance: reinforced cell walls create a more effective physical barrier against temperature fluctuations and environmental stress.
Application Protocol
Shake thoroughly before use. Add a maximum of 1 ml Silic Rock per litre of water (1:1000 dilution ratio). Apply at every watering event throughout the complete cultivation cycle. The 0.25L format yields up to 250 litres of working solution. Always add Silic Rock first to your water reservoir and allow full dissolution before incorporating other nutrients. Note: Silic Rock is organically derived and is not compatible with hydroponic systems (NFT, DWC, aeroponics). Flush irrigation lines after each use if applicable.
Integration with Plagron Nutrient Lines
With an NPK profile of 1.5-0-1.7 and 1.0% SiO₂, Silic Rock functions as a supplement rather than a replacement for base nutrition. Pair it with Power Roots 0.25L for enhanced root development, or combine with Sugar Royal 0.25L during flowering for improved terpene production. For growers on soil-based substrates, Silic Rock addresses the silicon gap that most commercial potting mixes fail to cover.

How many litres of nutrient solution does Plagron Silic Rock 0.25L produce?
At the maximum dosage of 1 ml per litre of water, the 0.25L bottle yields up to 250 litres of ready-to-use nutrient solution. This is sufficient for multiple cultivation cycles in a small-scale growing setup.
Can Silic Rock be mixed with other Plagron products?
Silic Rock is fully compatible with all Plagron nutrient products. However, always dissolve Silic Rock in water first and allow complete dissolution before adding any other fertilisers or stimulators to prevent chemical interactions.
Why is Plagron Silic Rock not suitable for hydroponic cultivation?
Silic Rock is organically derived, which means it can form precipitates in recirculating hydroponic systems such as NFT, DWC, and aeroponics. These deposits may cause blockages. Use Silic Rock exclusively with soil, coco, or other drain-to-waste substrate methods.
Is the 0.25L format of Silic Rock sufficient for a small grow room?
For a setup with a few plants, 0.25L typically covers a complete growth cycle. Growers with larger setups or multiple cycles should consider the 0.5L or 1L formats for better cost efficiency.
