Sponge rock, also known by the name Perlite, is a very common ingredient in orchid mixes and for good reason. Sponge rock decreases compaction of mix, increases aeration and retains moisture. Sponge rock is a volcanic glass that expands when heated and becomes very porous. Medium sponge rock, #3, is the perfect size for a wide range of mixes and is a component in our general purpose orchid potting mix. Small Sponge Rock and Large Sponge Rock are also available.

Medium Sponge Rock is also one of the quality orchid mediums available in our Select-A-Blend custom orchid mix. Select-A-Blend is unique because we let YOU create the blend with any 12 scoops from our menu of 57 orchid mix ingredients. Try Select-A-Blend the next time you repot an orchid. This unique custom orchid mix offering is one-of-a-kind and helps make repotting orchids simple and fun!
