China Rockwool Grow Cubes - Growing Medium Starter Sheets

Rockwool Grow Cubes (1.5 Inches) - Growing Medium Starter Sheets
Rockwool (Mineral Wool/Rock Wool) is a natural media made from a volcanic rock (basalt).

Rockwool (Mineral Wool/Rock Wool) 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 (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

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.
