Ausperl Horticultural Perlite is a heat-expanded volcanic rock processed into lightweight, porous white granules. Sterile, pH neutral, odorless, and permanent. It does not decompose or compact over time. Available in two grades: P400 (1–4 mm) as a medium particle, and P500 (3–6 mm) as a coarser particle. Unlike vermiculite, perlite holds very little water; its primary function is improving drainage and aeration, making it the right amendment for plants that need soil to dry out between waterings. Available in 5L for home use and 100L for larger projects or regular mixing.

Each grade suits different tasks:

  • P400 (1–4 mm): A versatile medium grade suited for general indoor potting mixes, seed starting, and propagating cuttings. Smaller particles integrate well into standard potting soil for a balanced, well-aerated mix
  • P500 (3–6 mm): A coarser grade that creates larger air pockets, preferred for orchids, succulents, cacti, and aroids where fast drainage and maximum root oxygenation are the priority

Across both grades, the most common home use is mixing into indoor potting soil at 20–30% by volume for tropical houseplants like monstera, pothos, and hoyas, or up to 50% for succulents and cacti where fast soil drying between waterings is critical. It works as a key component in orchid mixes, gives cuttings a clean sterile medium to root in before moving to soil, and blends into outdoor container and raised bed mixes to prevent compaction and keep roots well-oxygenated.

What Our Customers Say

Real reviews of our products & store by verified customers

This is definitely an excellent potting mix!

Once I replaced the mix of my alocasia with this, it started thriving and pushing out new sprouts. It's a chunky and airy mix so watering becomes more frequent but great for plants that hate wet feet and get root rot fast.

This is my third purchase of this potting mix, and it continues to impress. The drainage is excellent, and my plants have been growing healthier than ever.

Ideal for both indoor and outdoor applications. High-quality potting mix. Even though I definitely don't have green fingers. A reliable mix that makes plant care so much easier. Highly recommended.

— S.U.

Can't find a better soil mix to start my plant journey with! 2 weeks in and my plants are flourishing!

— H.K.

My alocasia stingray suffered from root rot and was attacked by mealy bugs. Potted an almost dead plant with just 1 yellowing leaf and few roots in this mix.

Today I cut off the last leaf and look, there is a sign of life. This potting mix is great. If I had known about this earlier, I would have fewer dead plants

Exactly 1 month since repot. This is a propagated anthurium and suffice to say, it absolutely loves the soil and the net pot.

I've had this plant since January and this is the first time it's growing 7 new leaves all at once! My only regret is that I wish bought a bigger pot because boy these roots grow fast!

— Gian J.

Excellent. Bought this as a recommendation from a friend and it works.

The soil is a good base and very suitable for adding amendments to suit the needs of your plant. I tried many soilless mixes, I like this one the most, for me it is the most versatile and easiest to use. Wish it came in a smaller 2L pack though. Good price and was delivered fast.

— A.N.

I'd highly recommend this potting mix as my alocasia roots grow very well and healthy in it. I'm also using it for other plant.
