Hydroton is a popular growing media especially for hobby hydroponic growers.

This media is lightweight, dust free, does not compact, and can be cleaned and sterilised for re-use.

It is an inert, pH neutral media which makes it ideal for hydroponics.

The expanded clay balls are very porous which allows them to absorb water and provide good aeration, drainage and capillary action.

The media can be used by itself or mixed with other medias used to improve drainage or to aerate the root zone of a plant.

The clay balls are also very attractive and can be used as a decorative top layer on pot plants to improve their appearance and to prevent the media in the pot from drying out.

Available in 25 or 50 litre bags in the following grades:

  • 4-8mm
