How is ECA or expanded clay aggregate used in pots, planters and mulching ?

Expanded Clay Aggregate (ECA) can be used as a plant substrate, or in concert with soil in pots, planters, and mulch. It has a number of advantages in this application. First, ECA is very light weight, which makes it easier to distribute evenly when mulching, and lowers the weight of pots and planters. It’s also a fantastic insulator, meaning that the delicate roots of plants will be protected from sudden cold snaps, which may otherwise kill them. Finally, ECA helps improve soil drainage and provides better oxygenation, which can spur faster and healthier plant growth
