Treat all plant surfaces including the undersides of leaves where most pests lay eggs. Repeat applications are usually required — follow the label's recommended interval between treatments to break the pest life cycle. Always apply during lights-off or in reduced light conditions to prevent leaf burn from foliar sprays.\u003c\/p\u003e\n\u003ch3\u003eIs Gnat Nix safe to use on plants in late flowering?\u003c\/h3\u003e\n\u003cp\u003eCheck the pre-harvest interval listed in the product instructions before applying Gnat Nix to plants in late flowering. Most pest control products specify a minimum number of days between last application and harvest. As a general rule, switch to the most plant-safe options available when within 2–3 weeks of harvest.

Expanded clay pebbles (LECA) should be thoroughly rinsed and soaked in pH-adjusted water before planting to remove dust and stabilise pH. Rockwool should be pre-soaked in pH 5.5 water for 24 hours before use to lower its naturally alkaline pH.\u003c\/p\u003e\n\u003ch3\u003eCan I reuse TetraBase Reusable DWC Grow Media?\u003c\/h3\u003e\n\u003cp\u003eInert media such as expanded clay pebbles can be sterilised and reused multiple times. Rinse thoroughly, soak in a 10% bleach or hydrogen peroxide solution, rinse again with clean water, and re-buffer before reuse. Coco coir can be reused for 2–3 grows if properly maintained and sterilised between cycles. Rockwool is typically single-use in commercial applications but can be reused in home setups with thorough cleaning.\u003c\/p\u003e\n\u003ch3\u003eWhat nutrient solution pH should I use with TetraBase Reusable DWC Grow Media?\u003c\/h3\u003e\n\u003cp\u003eTarget pH 5.8–6.2 for coco and hydro inert media. Soil users should target 6.0–6.5. Maintaining pH within the optimal range ensures all macro and micronutrients remain soluble and available to plant roots. Use a calibrated pH pen and adjust with pH Up or pH Down solution as needed after mixing your nutrient solution.\u003c\/p\u003e\n\u003ch3\u003eDoes TetraBase Reusable DWC Grow Media ship fast within Australia?\u003c\/h3\u003e\n\u003cp\u003eYes — TetraBase Reusable DWC Grow Media ships from our Australian warehouse with fast tracked delivery Australia-wide. Most east coast orders arrive within 2–5 business days. WA, NT, and TAS orders typically arrive within 5–12 business days.\u003c\/p\u003e","brand":"TetraBase","offers":[{"title":"Default Title","offer_id":43213540524095,"sku":null,"price":279.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/6898\/8479\/files\/tetrabase-icons-600x338.webp?v=1777864304"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/6898\/8479\/collections\/clean-bags-with-monkey-faces-only.png?v=1779116069","url":"https:\/\/apexgrow.com.au\/collections\/grow-mediums.oembed","provider":"Apex Grow","version":"1.0","type":"link"}
