Mother Earth® Perlite #4, 4 cu ft Bag

Mother Earth Perlite is naturally occurring siliceous rock that expands up to 20 times its original volume when heated to 1600° F.

This produces a growing media that has a neutral pH of 6.5 - 7.0 and adds porosity to soil and soilless mixes.

Mother Earth Perlite is one of the largest perlites on the market, with the Mother Earth Perlite #4 measuring around 1" in size and Mother Earth Perlite #3 measuring around 1/2".
