China Horticultural Rockwool Slabs for Vegetable Cropping

Horticultural Rockwool Slabs for vegetable cropping
Rockwool is a horticultural growing media made from the natural ingredients Basalt rock and Chalk. These are then melted at 1600° C into a lava which is blown into a large spinning chamber, which pulls the lava into fibers like "cotton candy." If you have ever visited a volcano you have probably seen these fibers flying around in the air surrounding the volcano. once the fibers are spun they are then compressed into a mat which is then cut into slabs and cubes. The rockwool granulates are just bales of uncompressed fibers. The process is very efficient, producing 37 cubic foot of wool from 1 cubic foot of rocks. Since rockwool is born in fire it renders the product chemically and biologically inert and creates the ideal growing medium for hydroponics. Since its development in Denmark in the early 1970's, rockwool has become the major vegetable and flower production medium throughout Europe and North America.
Horticultural Rockwool growing media is primarily available in two general formats. First, as rigid slabs, blocks, and cubes known as "bonded" products because the fibers are held together with a "gluing" or binding agent which renders them stiff and brittle. This is the primary format for the vegetable and cut flower industries. Secondly, rockwool is available as a highly refined and consistent hydrophilic or hydrophobic granulate which is basically water absorbent or water repellent. This format can be used as a component in various peat moss based soilless media or for ground bed incorporation to improve the tilth of heavy clay or light sandy soils.

Applications of rockwool (Mineral Wool/Rock Wool) include thermal insulation (as both structural insulation and pipe insulation, though it is not as fire-resistant as high-temperature insulation wool), filtration, soundproofing, and hydroponic growth medium.

Rockwool (Mineral Wool/Rock Wool) is a nice clean media which has a perfect Air:Water ratio and comes in a ready to use cube format.

Usage:

Rockwool /Rock wool Use in Hydroponic Aquaponics
Rock wool is an important grow medium in modern agriculture,is suitable for Industrialized planting of vegetables,fruits and flowers,such as Tomatoes,cucumbers,pimento etc.

Rockwool (Mineral Wool/Rock Wool) is very good for starting seeds and propagation of plant by rooting cuttings. And the plant with the cube can be planted directly in the garden or used in hydroponic systems.
Rockwool (Mineral Wool/Rock wool) can be engineered to hold large quantities of water and air that aid root growth and nutrient uptake in hydroponics; their fibrous nature also provides a good mechanical structure to hold the plant stable. The naturally high pH of mineral wool makes them initially unsuitable to plant growth and requires "conditioning" to produce a wool with an appropriate, stable pH.
Rockwool/Rock Wool Use in insulation
Though the individual fibers conduct heat very well, when pressed into rolls and sheets, their ability to partition air makes them excellent insulators and sound absorbers. Though not immune to the effects of a sufficiently hot fire, the fire resistance of fiberglass, stone wool, and ceramic fibers makes them common building materials when passive fire protection is required, being used as spray fireproofing, in stud cavities in drywall assemblies and as packing materials in firestops.
