It is a purpose-designed hydroponic support structure designed to solve the specific problems that conventional media creates in DWC environments. Most substrates introduce some level of organic matter, pH interaction, or particulate contamination over time. TetraBase eliminates all three. Made from 100% recycled materials and manufactured in the USA, it is built to last across multiple grow cycles without performance degradation. For growers running clean, high-performance DWC systems, it is the most cost-effective and system-stable media available.\u003c\/p\u003e\u003ch3\u003eSustainability and Long-Term Value\u003c\/h3\u003e\u003cp\u003eTetraBase is 100% reusable across multiple grow cycles, made from recycled materials, and eliminates the need for single-use growing media. This reduces long-term operational costs and waste output, making it a premium, cost-saving solution for serious and commercial growers focused on efficiency and environmental responsibility.\u003c\/p\u003e\u003ch3\u003eFrequently Bought Together\u003c\/h3\u003e\u003cp\u003eTetraBase is designed for clean, high-performance DWC environments.

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","url":"https:\/\/apexgrow.com.au\/products\/tetrabase-reusable-dwc-hydroponic-grow-media-australia","provider":"Apex Grow","version":"1.0","type":"link"}
