rock wool for plant

详情

Rockwool is a horticultural growing media made from the natural ingredients Basalt rock. It is also a great tool for smaller growers who can benefit just as much from its use in a range of different systems and situations. While rockwool is relatively easy to set up and use, it does require some monitoring and irrigation adjustment to make the best of its ability to hold high levels of moisture and aeration at the same time.

Advantages of Rockwool

RETAINS WATER - Rockwool holds an incredible amount of water which gives you a buffer against power outages and pump or timer failure.

HOLDS AIR - Rockwool holds at least *8 % air at all times (unless it is sitting directly in water). This supplies the root zone with plenty of oxygen, making overwatering less likely.

COMES IN A VARIETY OF SIZES AND SHAPES - From 1" cubes designed for use in propagation, to 3"x*2"x*6" slabs capable of holding the root systems of huge plants, Rockwool comes in many sizes, including loose so you can fill pots or containers of any size.

CLEAN AND CONVENIENT - Rockwool holds together very well so it can't spill. It also comes wrapped in plastic, making it easy to handle and keeping evaporation to a minimum.
