Seven pound bag of leca clay pebbles

These listings feature a 7lb bag of expanded clay media, providing a mid-range volume for home growers. These pebbles are an effective choice for deep water culture or drip irrigation systems. The irregular shapes and sizes, ranging from 4mm to 16mm, create a complex network of spaces that hold both humidity and oxygen for the roots.

The clay material is durable and does not break down easily, even when submerged in water for long periods. This makes it a reliable support for the root systems of larger plants like tomatoes or peppers. Before use, it is generally recommended to rinse the pebbles to remove any dust created during shipping, ensuring a clean system.

A 7lb bag is a practical amount for refreshing an existing system or starting a new medium-sized grow tray. The pebbles are chemically inert, so they won't interfere with the electrical conductivity or pH of your nutrient reservoir. Their natural earthy color also makes them an attractive choice for decorative indoor plant displays or terrariums.
