Rockwool is made from molten rock spun into fibers like cotton candy. It's
then pressed into different shapes and cut into cubes and slabs. The cubes and
slabs feel like a sponge and will not breakdown. The small Multiblocks and
Miniblocks can be used for starting cuttings or seeds. After the plants grow out
of the small blocks, you can place them in the holes in the larger growing
locks. From there you can place them on a slab for larger plants. Although the
rockwool can be heat sterilized after use and re bagged, most hobby growers just
throw them away after use. The Grodan Growcubes are small squares of rockwool
about the size of a sugar cube. They are used for filling pots or mixing with
Hydroton for added moisture. The Granulated rockwool is also for filling pots
and is less expensive than the Growcubes but does not have the same aeration.
