Expanded perlite particles are lightweight and insulated glass bubbles that can hold water and air. This provides many benefits for hemp growers: Retains water in three ways: In between individual grains, in channels leading to the cores of the grains, and on the highly irregular surfaces of each particle.
demonstration of a new manufacturing process based on the principle of flotation [23-28]. The new process appears to be capable of extending the limitation of perlite applications, allowing us to manufacture samples for exploring novel mechanical behavior of consolidated expanded perlite particles.
