Claydite is made of baked clay and is designed for drainage. This is a natural, environmentally friendly material. It is chemically inactive. Thanks to the porous structure of expanded clay it drains the soil well, keeping the roots from overflow. It facilitates air circulation - free access to roots. APPLICATION AREA: Claydite is placed on the bottom of the pot. For optimal drainage the expanded clay is filled to 20% of the total volume of the pot. Top with a substrate, mixed with perlite, vermiculite, soil.
