Hydro Clay – The Ultimate Growing Medium

Available Sizes
10L and 50L

Professor’s Nutrients Hydro Clay is a premium growing medium made from 100% natural lightweight expanded clay aggregate, also known as LECA.

Formed into uniform 8-16mm round pebbles, Hydro Clay is lightweight, porous, and designed to improve aeration, drainage, and root development for healthier plants.

Ideal for a wide range of growing applications, Hydro Clay can be used on its own or blended with other substrates.

Its high porosity helps increase oxygen availability around the root zone, while its moisture retention supports consistent plant hydration.

With zero nutrient value and a pH-neutral profile, it gives growers full control over feeding programs.
