Expanded clay pebbles forty liter bag

This large 40 liter bag of expanded clay pebbles is intended for growers who need a significant amount of media for their hydroponic systems. The pebbles range in size from 4 to 16 mm, providing a varied texture that supports root attachment and air circulation. The brown clay is fired at high temperatures to create a porous, lightweight material.

Because these pebbles are pH neutral, they will not interfere with the nutrient balance of your water. They are an excellent choice for flood and drain systems, deep water culture, or as a drainage layer in traditional pots. The material is very durable and can be sterilized and reused many times, making it a sustainable choice.

This set of media is ideal for filling large Dutch buckets or multiple net pots in a vertical tower. The round shape of the pebbles allows for plenty of interstitial space, ensuring that roots always have access to oxygen. This bulk quantity is a practical purchase for anyone setting up a new garden or expanding an existing hydroponic operation.
