VERMICULITE
Mineral with lamina structure close to the microns, expanded at 900ºC.
When the water contained in its laminae is vaporized, the heat makes it explode into a multitude of thin laminae proportionate to the air content.
Applications
Ideal for mixing with substrates of balanced aeration and hydration.
The elasticity and lightness prevent the hardening and asphyxiation of the substrates and allow the roots to breathe better.
