Perlite is a form of volcanic glass that is mined and heat treated to create small beads of lightweight porous material that retains moisture. Perfect incubation medium for reptile eggs and also for raising humidity within incubators. Sterile and ph balanced. Coarse ground for maximum surface area to mass ratio. Perlite is popular for growing seedlings and soil mixtures as it creates lots of room for healthy root development and helps to prevent compacted soil.
