Oxygenation: the loose, uncompressed structure combined with perlite creates high porosity, ensuring continuous oxygen supply to roots. Water retention: coco fibres hold moisture efficiently while preventing oversaturation, enabling stable hydration cycles between irrigations. Nutrient stability: pre-buffered coir maintains optimal EC and pH levels, allowing precise nutrient uptake without fluctuation.\u003c\/p\u003e\u003cp\u003eThe result is faster root establishment, improved nutrient efficiency, and a significantly reduced risk of root disease across all system types.\u003c\/p\u003e\u003ch3\u003eSystem Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eLoose, uncompressed substrate with immediate usability\u003c\/li\u003e\n\u003cli\u003ePre-buffered and washed.

UGRO Pure Max Air combines uncompressed structure with an integrated perlite blend, delivering a substrate that is ready to use, structurally stable, and optimised for both water retention and oxygen availability. The pre-buffering process removes excess sodium and potassium from the coir, ensuring the medium does not interfere with nutrient programs from day one.\u003c\/p\u003e\u003ch3\u003eFrequently Bought Together\u003c\/h3\u003e\u003cp\u003eUGRO Pure Max Air will perform excellently with coco-specific nutrient programs.

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 UGRO Pure Max Air 50L + Perlite?\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 UGRO Pure Max Air 50L + Perlite?\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 UGRO Pure Max Air 50L + Perlite ship fast within Australia?\u003c\/h3\u003e\n\u003cp\u003eYes — UGRO Pure Max Air 50L + Perlite ships from our Australian warehouse with fast tracked delivery Australia-wide.
