Perlite is a non-crystalline form of volcanic glass that expands and becomes porous when heated to 1600F.  The water molecules trapped inside the rock turn to vapor and cause the kernel to expand just like popcorn!

• Coarse and chunky
• Neutral PH
• Mined in the USA
• Can be added to any other growing media to improve texture, aeration and drainage
