Grotek Pro-Silicate Pro-Silicate from Grotek is a product that bolsters plants against pests and helps with support.Nutrient blends tend to not have silicon in them because it doesn't sit well with other ingredients. As such, plants can suffer from silicon deficiency which manifests as a weakness in cell walls. This can cause the plant to become a little limp and unable to support a large yield. Plants require a certain amount of silica to maintain a rigid cell wall. Pro-Silicate provides this extra element, allowing the plant to grow big and strong with an increase in disease and pest resistance.Not only that, Pro-Silicate provides degree of potassium too to help with all plants processes. GROTEK PRO SILICATE PLANT RESISTANCE Pro-Silicate(tm), which contains a high level of silica and soluble potash, was created for hydroponic systems and soilless media. Although silica is not an essential nutrient for plants, it can be found in large amounts in macro quantities. Silica has been shown to improve cell walls and cell integrity and make plants more resilient to heat and drought. Although silica is not essential for most crops it can help virtually all species of plants by supporting the development of strong cell walls. For strong plant performance and tolerance to abiotic stress like heat and drought, rigid cell walls are essential. Pro-Silicate provides the nutrients needed for better flowering and fruiting by providing two potassium sources (potassium silicate, and potassium chloride).Use Pro-Silicate during vegetative and reproductive growth. Pro-Silicate is an extremely strong base.
