Product Description

Rockwool Cubes Hydroponics Growing Media

Rock wool, a lightweight hydroponic substrate,
Is manufactured by melting basaltic rock (and dolomite)  and spinning the melted basalt into fibers. The fibers are then coated with a hydrophilic agent, compressed, cured, and cut into large rectangular shapes of rock wool..

Because rock wool and other stone or mineral wools used in horticulture originate from rock, they are considered by many to be a natural product. Rock wool is a widely utilised substrate in commercial horticulture for the production of crops as diverse as tomatoes, melons, cucumbers, peppers, strawberries, herbs, and cut flowers; however it can also easily be used by smaller hydroponic growers wanting to take advantage of improved root zone technology.

Characteristics & Benefits:

Completely sterile and inert - ideal hydroponic growing medium. Reduced risk of pests and disease. 
 Even root growth - predominantly vertical fiber structure means identical levels of resistance for each root, so roots grow evenly. 
Increased root development - structure of the rockwool is designed for optimum air / water balance and accelerated rooting. 
Uniformity - quality and structure is uniform, so water content and EC (CF) will remain the same for every plant. 
 Re-wetting - It is is easy to re-saturate if it dries out, reducing the risk of root damage.
