📖 Description
Orku super coarse perlite for maximum drainage and airflow in pots and hydroponic systems.
Perlite is a heat-expanded volcanic rock that forms light, porous granules. Super coarse perlite has the largest particles and the highest air porosity of the common grades, giving the most drainage and airflow around plant roots.
It holds enough moisture to work as a hand-watered medium, yet drains freely enough for recirculating drip irrigation. Use it on its own as a hydroponic medium, or mix it through potting soil for plants that hate wet feet, such as orchids, succulents and aroids.
The supplier states that this product is an Australian Organic registered garden product and farm input, and comes from a 100% Australian-owned company.

⚠️ Important Information & Care
Dry perlite is dusty. Lightly wet it before handling, pouring or mixing, or wear a dust mask, and avoid breathing the dust. Keep out of eyes.
Perlite is very light and floats, so it can rise to the surface of pots after heavy watering and can blow around when dry. Store bags sealed, in a dry place, out of reach of children and pets.
Perlite is a growing medium only and contains no nutrients; feed plants with a suitable fertiliser. Results depend on your plants, mix, watering and conditions. Volumes and weights are approximate.
