Clay Pebbles, Clay Balls or Lightweight Expanded Clay Aggregate - The only thing you need for a simple semi hydro set-up (except water of course). The small balls of clay wick water upwards, meaning a little pool of water at the bottom of a pot made for semi hydro can hydrate all the way to the top! The balls also provide massive chambers of oxygen for roots to grow super strong which you will see the rewards of in your foliage. Conversely, you can add clay balls into soil for extra water retention in your mixture.
A favourite amongst the passive hydroponics lovers! This is a brilliant and versatile growing medium that has been used for many years for everything from aquarium biological filtration to drainage layers in tropical terrariums. As a stand alone material, it is almost unilaterally used for propagating plants for expedited growth.
The porous nature of this material has a fantastic behaviour of evenly wicking water, minerals and nutrients from a reservoir directly to the roots that crave them. It removes the need for drainage holes in glass or ceramic pots as simply filling a small reservoir from the top will keep the whole system fully hydrated and transporting those delicious nutrients to roots!
