Bio Active Drainage Balls - Clay Balls 100g

Clay balls are an essential part of any bio-active setup. They create a drainage layer to allow water drainage from the soil above and help prevent bacteria and mould growth.

Please note you need to place a drainage membrane above the balls to get the best result when using them or the soil will simply sink into them.

100g of medium-large clay balls are provided. Enough for a larger enclosure or a couple of smaller ones.
