Beneficial Properties of Hydroton:
Water Retention & Drainage - This material is filled with tiny pores, much like a ‘micro sponge’. Because of this, it holds the perfect amount of water and drains any excess to prevent overwatering.
Aeration – Unlike soil that compacts and reduces available oxygen over time, hydroton retains its shape and allows for continuous oxygen exchange, keeping your plant roots healthy.
PH Neutral – In gardening, it is important to have a growing medium that isn't too acidic or basic. This material is a pH neutral product, so you won’t have to worry about any nutrient lockup or plant health issues due to unstable pH.
Sterile – It is produced in large rolling kilns that ‘bake’ it into its final shape. Since high temperatures are used, hydroton comes to the gardener as a sterile product. This is highly beneficial because you don’t want to introduce disease and harmful bacteria into your garden.
