Key Benefits

Give your substrate a pumice boost

Better soil structure

The high porosity of pumice improves soil aeration and drainage, making for healthier roots and happier plants.

Moisture boost

For a (volcanic) rock, pumice is surprisingly water retentive. Helping to boost those all-important tropical conditions and keep your plants happy.

Nutrient lock

Pumice binds to available nutrients, and can release them slowly over time - providing stable fertilization support.
