When it comes to today’s gardening and greenhouse work, perlite does more than fill space – it shapes how water moves through the mix and how roots grow.
Inside the AUSPERL Group, horticultural perlite meets strict quality standards to perform reliably, not only ship large quantities.
Manage water and air effectively High total porosity stays steady with consistent air-filled porosity
- Predictable water retention curves for irrigation control
- Quick runoff keeps roots from low oxygen
- Root development benefits Peels that break down easily let roots grow deeper.
That happens because there is little pushback from the layer itself.
- Stable structure over time (no compaction)
- Even moisture spread across pots and slabs
Typical substrate mixes Peat mixed with coco plus perlite helps keep things steady – holding water while also allowing good airflow
High-perlite mixes lead to crops vulnerable when too much water is applied
Tailored particle sizes for trays, pots, or hydroponic systems
Things farmers need to spell out.
- Particle size distribution typically shows fines alongside coarser particles
- Focus on empty air space plus soil’s ability to retain water
- Crop type and irrigation strategy
