What’s included: one 1-quart resealable pouch of horticultural perlite — expanded volcanic glass processed for gardening use. The particles are lightweight, sterile, and pH neutral, designed to be long-lasting in potting mixes. Perlite resists compaction so soil structure remains open, allowing roots to access both air and water more effectively over time.

Air and moisture management: this organic perlite significantly improves drainage and root-zone aeration. The porous granules can hold several times their own weight in water (commonly cited around 3–4×), yet they also let excess moisture drain away to reduce the risk of waterlogging and root rot. At the same time, the particles help retain available moisture and nutrients near roots rather than allowing everything to run off immediately.

Versatile uses: suitable for blending into potting soil, preparing mixes for succulents, cacti, orchids, carnivorous plants, herbs, and tropicals. It’s also compatible with hydroponic systems and seed-starting media (alone or combined with coco coir). Perlite works for specialty mixes like Venus flytrap substrate and is handy for decorative layering, terrariums, or floral arrangements and craft projects.

Packaging and storage: the material is supplied in a durable, resealable pouch that helps keep the perlite clean and dry between uses. The pouch is easy to open and pour from, making it practical whether you’re refreshing a few houseplants or preparing multiple pots for a larger planting session.

How to use: for general potting mixes, blend at roughly a 1:3 ratio (one part perlite to three parts potting soil) to enhance drainage and lighten the mix. For hydroponics or seed starting, perlite can be used on its own or mixed with coco coir. A thin top layer of perlite can improve appearance while helping surface moisture evaporate evenly and reducing crusting.

VerdictThis 1 QT pack of organic horticultural perlite is a reliable amendment for improving potting mixes and seed mediums. It’s an inert, pH-neutral granular material made from expanded volcanic glass that keeps soil from packing down while helping excess water drain away. Easy to store in its resealable pouch and versatile across succulents, orchids, herbs and hydroponic setups, it’s a practical addit

Repeat buyer

This is my second bag; I’ll keep using it for repots and new starts.

Diana St Ledger-Roty 5/5

Adds needed drainage to potting mixes

Perfect for folding into potting soil — I found many store mixes include very little perlite. I stirred this into an 8-quart bag and noticed roots had more air and excess water drained faster, cutting down on soggy soil. The granules looked clean and performed well, so I’m pleased with the quality.

Helped my roses

Purchased to encourage stronger roots and fuller blooms on my rose bush.

Lorene 5/5

Transformed my potting routine

This product has been a revelation. I add about half a cup when I make new soil and plants respond quickly — they’ve noticeably increased in size since I started using it regularly.
