THE GROWER AND THE GROWING MEDIUM

As the grower begins to experiment with
soil types and mixing them they may begin to
look at alternative growing mediums such as
rockwool or Clay pebbles. These are mostly
artificial grow mediums designed to contain all
the plants mineral needs and allow air to get
the roots to promote good growth.
