Strengthen your garden’s resilience and improve overall plant structural integrity with Grotek Pro-Silicate. This professional-grade silicon supplement is a vital additive for growers looking to fortify their plants against environmental stress, heat, and pests. By providing a readily available source of potassium silicate, this formula helps build thicker cell walls and sturdier stems, ensuring your crop can support heavy floral sets and high-quality yields.
Grotek Pro Silicate is particularly essential in hydroponic systems and coco coir grows, where natural silica levels are often non-existent. When integrated into your regular feeding schedule, it acts as a protective barrier, reducing transpiration and improving drought resistance, making it an indispensable tool for maintaining a healthy, high-performance grow room.
Key Benefits of Grotek Pro-Silicate
- Enhanced Structural Strength: Silicon is deposited in cell walls, creating thicker stems and tougher leaves that can easily support heavy fruits and flowers.
- Stress Resistance: Improves the plant's ability to withstand extreme temperatures, drought, and high-intensity lighting.
- Improved Nutrient Uptake: Helps balance the intake of essential elements and can aid in the prevention of toxicities from minerals like manganese and aluminium.
- Reduced Water Loss: By strengthening the outer leaf layer, Pro Silicate reduces transpiration, helping plants stay hydrated for longer.
- Optimal pH Buffering: Acts as a mild pH up, helping to stabilise nutrient solutions in acidic growing conditions.
- Pest and Disease Defence: Toughened cell walls make it harder for biting insects and fungal pathogens to penetrate the plant tissue.
How to Use Grotek Pro-Silicate
Grotek Pro Silicate should be used from the early vegetative stage through to the end of the flowering cycle. Because it is a highly alkaline product, it requires a specific mixing order to avoid nutrient lockout.
Dosage Rates:
- Hydroponics/Soil/Coco: Mix 0.5ml to 1ml per litre of water.
- Crucial Mixing Instruction: Always add Pro Silicate to your water reservoir first and stir thoroughly before adding any other nutrients or additives.
- pH Adjustment: After adding all nutrients, always check and adjust your pH levels using a pH testing kit, as Pro Silicate will raise the pH of your solution.
- Important for Soil Growers: Because Pro Silicate is highly alkaline, it will raise the pH of your soil over time if not monitored. Always adjust your final nutrient solution to a pH of 6.0–6.8 when growing in soil to ensure you don't lock out other nutrients.
For maximum results, combine Pro-Silicate with a robust base nutrient like Grotek Solo-Tek Grow to ensure a complete mineral profile during the vegetative phase.
Can be used in all growing mediums, including soil, coco coir, and hydroponic systems.
Available in 4 litres.
Frequently Asked Questions
Can I use Grotek Pro Silicate as a foliar spray?
Yes, Pro Silicate can be used as a foliar application at a rate of 0.5ml per litre. This provides a direct boost to leaf strength; however, avoid spraying under high-intensity lights or in direct sunlight to prevent leaf scorch.Why must I add Pro Silicate to the reservoir first?
Silicon is highly reactive. If added to a concentrated nutrient mix, it can cause "fallout," where minerals like calcium and magnesium bind together and become unavailable to the plant. Adding it to the water first prevents this chemical reaction.Does Pro Silicate replace my Cal-Mag supplement?
No. While Pro Silicate provides potassium and silicon, it does not contain calcium or magnesium. If you are using RO water or growing in coco, you should still use a dedicated calcium and magnesium additive alongside it.How often should I apply Pro Silicate?
For best results, it should be used with every watering or reservoir change. Consistent application ensures that as the plant grows and creates new cells, silicon is always available to reinforce the new growth.SKU: 1849 Free delivery on orders over £60*
