High Quality Basalt Fiber Materials Gardening & Hydroponics System & Insulation Rockwool Cubes Rockwool Board  

Rockwool is a general name for fiber materials that are formed by spinning or drawing molten minerals (or "synthetic minerals" such as slag and ceramics).

Applications of rockwool 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 is a nice clean media which has a perfect Air:Water ratio and comes in a ready to use cube format.

Main Size of rockwool as follows

Usage

Rockwool Use in Hydroponics System & Gardening

Rockwool 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 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 rockwool makes them initially unsuitable to plant growth and requires "conditioning" to produce a wool with an appropriate, stable pH.

Rockwool 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.
