Mother Earth® Perlite is naturally occurring siliceous rock that expands up to 20 times its original volume when heated to 1600° F. This kilning process is very similar to popping popcorn and produces a growing media that is sterile and has a neutral pH of 7.0. The exceptional physical properties of this perlite make it tops in the perlite world for adding porosity to soil and soilless mixes. This perlite has numerous hydroponic applications as well. The #4 is the largest perlite on the market and averages a whopping size of around 1 in. The #3 measures around 1/2 in and the Coarse is about 1/8 to 1/4 in.

The original Hydroton® brand expanded clay is a unique, lightweight expanded clay aggregate made in Germany. This natural clay is mined, formed into pellets, then kiln fired at high temperatures to cause the clay to expand into tough, lightweight balls. Hydroton® brand expanded clay is semi-porous and generally does not float like other products can. For best results, rinse all expanded clay before use. It is reusable as long as it is thoroughly cleaned between uses. 50 liter bags feature an easy-pour spout. Size specification is 8–16 mm.

ReadyGro™ Aeration Formula is specifically designed for automated hydrogardens and self-watering planters with small to midsize plants. This blend is lighter and contains higher air content than the moisture formula. The ReadyGro™ Moisture Formula (1 to 2 waterings daily) is specifically designed for hand-watering, automated pots and planters with large plants. This formula contains more coir fiber and pumice stones. This formula will give plants enhanced moisture content for longer duration in between feeding and help anchor large plants.
