Medium Pumice stone 3 – 8mm
Our Pumice Rock comes in 2 sizes:- 3-8mm and 10-15mm
These incredible rocks are formed when lava cools quickly above ground, creating a unique medium with many air pockets.
We use it within our Bark mixes to “open up” the mix and allow more air to the roots – remember Orchid roots love Moisture NOT Water!
We find it essential for our Long Petaled Orchids.
