structure fairly well, have a balanced pH, and are easy to handle. They
come joined together as 162 cubes per pad that fit into a standard flat. They
are easily separated as they are joined only at their bases. I would not use
them for tomatoes, peppers, eggplants, or cucumbers as the horticube is
very small and not easily transplanted to a larger block.
The best growing cubes and blocks are those of rockwool (Figure 2.2).
Rockwool has very good physical properties of drainage, aeration, water
