Made from spun basalt rock fibers that are then formed into slabs or cubes, rockwool is a popular growing substrate for hydroponic gardening. Rockwool, also known as stonewool, is perfect for seed starting, ebb and flow systems, and drip irrigation hydroponic systems due to its inert properties and the fact that it does not absorb water - leaving it available to the plants for growth and development.
HTG Supply offers rockwool in a variety of options, including cubes, blocks, slabs, whatever you need to get the most out of your hydroponic garden! Order today!
