This ten pound bag of expanded clay pebbles offers a versatile growing medium for various types of indoor gardening. The pebbles range from 9mm to 12mm in size, providing a porous surface that holds moisture while allowing for excellent drainage. This makes them a popular choice for orchids and other plants that dislike sitting in stagnant water.
The lightweight aggregate is pH neutral and does not break down over time, meaning it can be cleaned and reused for many years. In hydroponic systems, these pebbles provide physical support for the plant's root structure while ensuring plenty of oxygen is available. They also work well as a bottom layer in traditional pots to improve aeration.
These natural clay stones are processed at high temperatures to create a durable, ceramic-like finish. They are clean to handle and do not compact like soil, which prevents root suffocation. This bulk quantity is sufficient for filling several medium-sized net pots or a large decorative planter for aquaponics or horticultural use.
