Perlite is a naturally occurring volcanic glass that undergoes a unique transformation when heated to high temperatures, expanding like popcorn into a lightweight, porous material. This expanded structure makes perlite an excellent soil amendment, improving aeration and drainage while preventing soil from becoming compacted. Ideal for custom potting mixes, our #3 perlite helps create a well-balanced blend tailored to the needs of various plants, from delicate orchids to lush leafy greens. It enhances root development by ensuring oxygen reaches the roots and excess water drains efficiently, reducing the risk of root rot. Whether used on its own for propagation or mixed with other ingredients like coco coir, compost, or other media, perlite is a versatile addition to any soil mix, supporting strong, healthy plant growth.
