UGRO Pure Max Air 50L + Perlite | Coco Coir Hydroponic Growing Medium Australia

UGRO Pure Max Air 50L + Perlite. High-Aeration Coco Coir Substrate for Hydroponics and Soil-Less Growing

UGRO Pure Max Air 50L is a premium, uncompressed coconut coir substrate made for maximum aeration, balanced water retention, and precision root zone control. This blend combines high-grade washed coco coir with perlite to deliver a loose, free-draining, oxygen-rich growing medium ideal for high-performance cultivation.

Unlike compressed coco products, Pure Max Air is ready to use straight out of the bag. Its natural uncompressed structure allows immediate root penetration and superior airflow. The perlite component enhances drainage and porosity, making it highly effective for preventing overwatering and root disease.

Key Benefits

• 50L Ready-to-Use Loose Coco Substrate. No expansion or hydration required before use.
• Coco and Perlite Blend. Optimised balance of water retention and aeration for consistent root zone conditions.
• Uncompressed Structure. Maintains maximum pore space for oxygen availability from first use.
• True Buffered and Washed Coir. Stabilised EC and pH for immediate nutrient compatibility.
• High Water-Holding Capacity. Supports consistent hydration cycles without saturation or dry pockets.
• Enhanced Drainage via Perlite. Reduces risk of root rot and anaerobic root zone conditions.
• Sterile and Clean Medium. Free from pathogens, pests, and contaminants.
• Sustainable and Renewable. 100% coconut by-product. A direct peat alternative.

How It Works

UGRO Pure Max Air improves three critical root zone variables. 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 the right EC and pH levels, allowing precise nutrient uptake without fluctuation.

The result is faster root establishment, improved nutrient efficiency, and a significantly reduced risk of root disease across all system types.

System Features

• Loose, uncompressed substrate with immediate usability
• Pre-buffered and washed. Stable EC and pH out of the bag.
• Perlite inclusion for enhanced porosity and free drainage
• Pathogen-free and sterile. No pre-treatment required.
• Compatible with all nutrient programs and irrigation systems

Applications

• Drip Irrigation Systems (Run-to-Waste)
• Hand-Watered Container Growing
• Greenhouse Production Systems
• Indoor Pot Cultivation
• Organic and Sustainable Growing Systems

What Sets It Apart

Most coco products on the market are compressed bricks requiring expansion, or loose coir without perlite, which limits drainage performance. 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.

Frequently Asked Questions

Do I need to prepare UGRO Pure Max Air 50L + Perlite before using it?

No. It's buffered and washed at the factory, so it goes straight from the bag into your pots. There's no rinsing, soaking or cal-mag charging needed before planting.

Can I reuse UGRO Pure Max Air 50L + Perlite?

Yes, for 2 to 3 grows if it's looked after. Pull out the old root mass and flush the mix with clean water before replanting. The perlite holds up well. Replace the mix once the coco breaks down into fine dust or smells sour.

What nutrient solution pH should I use with UGRO Pure Max Air 50L + Perlite?

Target pH 5.8 to 6.2 for coco and hydro inert media. Soil users should target 6.0 to 6.5. Keeping pH within this range keeps all macro and micronutrients 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.

Does UGRO Pure Max Air 50L + Perlite ship fast within Australia?

Yes, UGRO Pure Max Air 50L + Perlite ships from within Australia with fast tracked delivery Australia-wide. Most orders to VIC, NSW, QLD, SA and ACT arrive within 2 to 5 business days. WA, NT, and TAS orders typically arrive within 5 to 12 business days.
