Always add additives to water rather than directly to concentrated nutrient solutions. Stir well after each addition and check EC and pH before use. Start at the lower end of the recommended dose range and increase progressively — additives are potent and more is not always better.\u003c\/p\u003e\n\u003ch3\u003eIs Growth Technology GT Silica compatible with organic and mineral nutrient programs?\u003c\/h3\u003e\n\u003cp\u003eGrowth Technology GT Silica is compatible with most hydroponic nutrient programs including both mineral and organic-based systems. If running a fully organic or biological program, check the formulation — some mineral additives can inhibit beneficial microbial populations. When in doubt, contact us at hello@apexgrow.com.au for compatibility advice specific to your setup.\u003c\/p\u003e\n\u003ch3\u003eCan I use Growth Technology GT Silica in soil, coco, and hydro?\u003c\/h3\u003e\n\u003cp\u003eYes — Growth Technology GT Silica is suitable for use across all growing mediums including soil, coco coir, perlite, rockwool, and all recirculating and run-to-waste hydroponic systems. Dose rates may vary slightly between growing systems — always follow the manufacturer's feeding chart for your specific medium.\u003c\/p\u003e\n\u003ch3\u003eDoes Growth Technology GT Silica ship fast within Australia?\u003c\/h3\u003e\n\u003cp\u003eYes — Growth Technology GT Silica ships from our Australian warehouse with fast tracked delivery Australia-wide.
