Light expanded clay aggregate, also commonly referred to as "grow rock", is ideal for indoor hydroponic growth because of its neutral properties - L.E.C.A. has no acid or alkaline characteristics. Hydroponics gardeners appreciate the neutrality of L.E.C.A. because so many are aware how difficult it is to maintain a perfect alkaline/acidic balance in soil gardening Because L.E.C.A. comes in the ...

Expanded clay is a lightweight aggregate formed by baking clay in a rotary kiln at 1100oC. This expands the clay into aerated modules with a tough outer shell. The resulting aggregate is inert, light, non-combustible, rot-proof and strong. The expansion process where the clay expands up to five times it’s initial volume means much less raw material is consumed. It is therefore a sustainable ...
