BuildASoil Pumice

This is the BuildASoil Way! Pumice makes soil that lasts forever and is more sustainable than throwing your potting soil away after each use. 3/8" x 1/4" Pumice is perfect for potting soil. 

• Optimizes drainage
• Retains and evenly distributes moisture and nutrients
• Promotes strong root growth
• Improves root aeration
• Low Heavy Metals
• Does not contain clay or organic material (i.e. montmorillonite, illite, kaolinite)
• Minimizes root diseases
• Clean from disease or weed seeds and environmentally friendly

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. 

Pumice is a natural, lightweight, volcanic material widely used in horticulture and hydroponics. The porosity of Pumice provides an abundance of air space maintaining aerobic conditions around the roots. The inert nature allows fertilization to be controlled in a very exact manner.

The porous nature and natural surface tension around the outside of the Pumice particles allow it to hold water yet retain sufficient air space to optimize drainage and promote strong root growth.

Its insulating properties increase the temperature of the plant food favoring plant nutrition and growth. Because of its chemical and physical properties, Pumice promotes excellent nutrition distribution, strong root development and excellent plant growth.

The absorbency of Pumice allows it to retain moisture and nutrients. The gradual release of the moisture and nutrients enables a considerable reduction in irrigation time. Because BuildASoil Pumice is mined, it is clean and free of disease spores and weed seeds, which is an advantage over river pumice.
