3/8"+ - 1/4"+ Pumice - Bonsai Soil, Succulents, Cactus & Soil Mixes - Screened Our 3/8"+ - 1/4+" pumice is ideal those wanting a clean hand screened pumice of a larger size for soil mix's.  Our pumice is a natural volcanic product mined in the Southern Cascades Mountains of Oregon.  You get only clean pumice... no rocks, roots or other debris. Known as the "rock that floats", pumice has many tiny gaps or air pockets. Pumice is very non uniform in size. Thus all sizes are approximate. The Pumice comes from the mine at 3/8 inch minus.  We then rescreen. to remove pumice over ¼  inch. All pumice that does not fall through our 1/4 inch screen is considered 3/8- 1/4 inch pumice. If you are concerned about the size of pumice you will receive and would like to order samples so you will know exactly what you will get, you can do so for the cost of shipping.  Then, if you decide to order 6 gallons or more, the freight cost of shipping the samples will be reimbursed.
