What is Hydroculture?

Hydroculture is a form of passive hydroponics and a way of growing plants without soil. Passive hydroponics systems often use an inert growing medium such as clay pebbles instead of soil. If you haven't experimented with hydroponics before, then passive hydroponics and hydroculture is a great way to get started.


A hydroculture system is often made up of five simple parts – clay pebbles (or a similar inert growing medium), culture pots, water level indicator, pot liners, and fertiliser.


Clay pebbles

Clay pebbles are the primary growing medium used in hydroculture systems. These expanded clay pellets take the place of soil. They are highly porous which means they are great for growing plants. Clay pebbles are effective at retaining moisture and nutrients, are fully inert, free from soil-borne pests and diseases, provide plenty of oxygenation at the root zone, and give your plants a sturdy support structure to grow and thrive.
