Last Longer Than Perlite & Has More Minerals
3/8" x 1/4" Pumice is perfect for potting soil.
Pumice is created when super-heated, highly pressurized rock is violently ejected from a volcano. The unusual foamy configuration of pumice happens because of simultaneous rapid cooling and rapid depressurization. The depressurization creates bubbles by lowering the solubility of gases (including water and CO2) that are dissolved in the lava, causing the gases to rapidly exsolve (like the bubbles of CO2 that appear when a carbonated drink is opened). The simultaneous cooling and depressurization freezes the bubbles in the matrix.
Pumice /ˈpʌmɨs/, called pumicite in its powdered or dust form, is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. It is typically light colored. Scoria is another vesicular volcanic rock that differs from pumice in having larger vesicles and thicker vesicle walls and being dark colored and denser.[1][2]

Consistent size and great price
This pumice is amazing quality for my bonsai soil mixes, and a very affordable price compared to high quality comparative products. I will use buildasoil products in every area of my garden.
I'm liking this stuff so far I added it to my mix for extra aeration in top of the perlite that came with my happy frog soil.
Perfect uniform size.
I have ordered the pumice several times. My last order consisted of several larger bags. This current order of pumice is the size of small marbles. Slightly smaller than the diameter of a dime. This is the perfect size IMO! Each bag is very close to the last as far as size and with consistency comes quality. The best part about all of this, I get all the above at such a great price!
