Hydro Rocks - 9ltr

Swell Premium Hydro Rocks are a hydro culture with many benefits that aid in water retention and the formation of a strong root system. This drainage substrate comes in a 9-litre bag that will create a thick layer in most terrariums that can be topped by other media. This drainage layer will trap excess water, so that soil dries, and offers a good grip to plant roots. Unlike other media, these rocks are a natural product, so you can be sure they won't release chemicals into the nutrients within your soil and water.

Why is a drainage layer useful?

Hydro rocks create a drainage layer which prevents your soil from becoming waterlogged, removes waste and creates a reservoir to ensure high moisture levels within your enclosure. Drainage layers are suitable for lifelong operation as they don't erode or degrade. With good a drainage layer system, you can create high humidity enclosures for rainforest animals like Chameleons and Dart frogs.
