Pro Liquids Silica Pro 5 Gallon

Silica Pro is a high-purity liquid potassium silicate formulated to supplement crops with soluble potash and highly plant-available silicon. Silicon is a beneficial element that supports plant structural integrity and enhances stress tolerance.

Advantages

• Strengthens plant structural integrity — Silicon deposits in cell walls as silica gel, creating a stronger physical barrier that enhances mechanical strength, reduces lodging (plants falling over), and improves overall stem, leaf, and root rigidity for more robust crops.
• Enhances stress tolerance — Silicon improves resistance to abiotic stresses like drought, heat, salinity, mineral toxicity (e.g., aluminum), and climate extremes by better water balance, reduced water loss, and improved physiological responses, helping plants maintain growth under challenging conditions.
• Boosts resistance to biotic stresses — It forms a protective layer that increases defense against pests (e.g., aphids, thrips, spider mites, sucking insects) and diseases (e.g., powdery mildew, fungal pathogens, gray leaf spot, root rot), often reducing incidence and severity without relying as heavily on chemical pesticides.
• Provides dual nutrient benefits — Supplies highly available soluble potash (potassium) alongside silicon, supporting overall fertility, nutrient uptake (including better absorption of elements like phosphorus), photosynthesis efficiency, and chlorophyll levels for enhanced growth and vigor.
• Improves crop quality and yield — Leads to better fruit/vegetable firmness, extended shelf life/post-harvest quality, reduced cracking or internal issues, higher yields in some cases, and improved overall plant health and productivity, especially in high-value horticultural or greenhouse crops.
• Versatile and efficient application — As a liquid, high-purity, soluble form, it's highly plant-available, easy to apply via foliar spray, fertigation, soil drench, or watering, and particularly effective in hydroponics, soilless media, or potassium-deficient soils.

Application

FERTIGATION - Delivered through an irrigation system, fertigation feeds plants while you water. This method ensures even distribution of nutrients directly to the root zone, making it efficient for larger gardens or automated systems.

FOLIAR - Apply directly to the leaves using a sprayer. This method allows for rapid nutrient absorption through the leaf surface, providing quick corrective action for deficiencies and boosting plant vitality during key growth stages.

SOIL DRENCH - Pour the diluted solution around the base of the plant to soak into the root zone. This deep-feeding method nourishes roots directly and is ideal for systemic nutrient uptake and long-term plant health.

TOP WATERING - Apply the solution manually over the soil surface with a watering can or hose. As water moves downward, nutrients are carried through the root zone, making this an easy, effective feeding method for container or in-ground plants.

Contains Beneficial Substance(s)

Derived from: Potassium Silicate

This product contains soluble silica (SiOâ‚‚) as a non-plant food ingredient.

Directions for Use

Apply as part of a complete nutrient program. Always premix into water before adding other nutrients. Adjust pH as needed after mixing. Do not mix concentrate with calcium products. Always dilute into water first.

Notes

Conduct a compatibility test (jar test) when mixing with other products. Maintain nutrient solution pH between 5.8 - 6.5.

Safe Handling & Precautions
