Pumice
DISCONTINUED1/4 inch Horticulture Pumice
Horticultural Pumice has been discontinued due to unstable supply and extreme quality issues within the USA. Please consider using Bonsai Block as an alternate. They have virtually the same pH value and are nearly identical in CEC. If your recipe requires pumice please consider Hess Pumice 3/8×8. You want to choose the non-MN version 3/8×8. This is as close to 1/4 inch that Hess offers.
