Silica isn't classed as an essential nutrient, but plants accumulate it in macro quantities for good reason - most base nutrient formulations leave it out entirely because it reacts poorly with other minerals in a concentrated blend, so a standalone silica source fills a genuine gap in most feeding programmes.\u003c\/p\u003e\u003cp\u003eOnce taken up, silica reinforces cell walls throughout the plant, giving stems and branches the rigidity needed to carry heavier flower and fruit loads without bending or snapping. That same structural strength translates into better resistance to heat stress, drought and the kind of physical damage that opens the door to pests and pathogens.\u003c\/p\u003e\u003cp\u003ePro-Silicate is alkaline, so it's added to the reservoir or final nutrient solution first, before other nutrients go in, to avoid unwanted reactions - never straight into a concentrated nutrient stock. It works across both the vegetative and reproductive stages of growth in hydroponic and soilless media alike.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual potassium sources\u003c\/strong\u003e from potassium silicate and potassium chloride\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrengthens cell walls\u003c\/strong\u003e for sturdier stems and heavier yields\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImproves tolerance to heat and drought stress\u003c\/strong\u003e through better cell integrity\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupports pest and disease resistance\u003c\/strong\u003e via stronger plant structure\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuited to hydroponic and soilless systems\u003c\/strong\u003e where silica is typically absent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsable through veg and bloom\u003c\/strong\u003e for season-long structural support\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cp\u003eActive minerals: potassium silicate, potassium chloride\u003cbr\u003eDose rate: 1.5-2.5ml per 4L of solution (1\/4-1\/2 tbsp per gallon)\u003cbr\u003eApplication: add to final nutrient solution only, never to a concentrate\u003cbr\u003eTarget solution pH: 5.8-6.8\u003cbr\u003eForm: alkaline liquid concentrate\u003c\/p\u003e","brand":"Grotek","offers":[{"title":"1L","offer_id":53500728115466,"sku":"GK-05877","price":10.95,"currency_code":"GBP","in_stock":true},{"title":"4L","offer_id":53525153022218,"sku":null,"price":39.95,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/1279-pro-silicate.png?v=1786377735","url":"https:\/\/hydrocropshop.co.uk\/products\/grotek-pro-silicate-1l","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
