Rockwool is a highly popular growing medium among hydroponic enthusiasts. Made of naturally occurring volcanic rock, it is an excellent option for plants that require a neutral pH level. The medium's small size and porous texture make it ideal for seed propagation and even acts as a natural insulator to maintain moisture levels in the root zone.
In addition to its structural benefits, rockwool is also an eco-friendly option for hydroponic growers. Since it is made from natural materials, rockwool is completely biodegradable and can be safely disposed of. Moreover, rockwool can be reused multiple times, making it more cost-efficient than other growing media. Horticulturists who select rockwool can rest assured that they are making a responsible choice for both their plants and the environment.
