Step 7Growing Media
Growing media
In this system, like plants growing in soil, the plants require a growing media, clearly soil is not the best option given its inability to breath in water.
I use expanded clay (balls)(fig. 24) a common hydroponic medium that allows good root ventilation, doesn't break down fast, and doesnt grow algae etc.,(avoid perlite, pumice other mediums as good as they are, they also grow algae on them )
