Rockwool Propagation Cubes

Description

Rockwool is produced from basalt rock, which is melted and then spun into thin fibres. These are mixed with a binding agent and compressed into slabs that are cut into the smaller cubes used for propagation.

Seasoned hydroponics experts swear by propagation cubes because of the support and good aeration properties they provide for strong root growth. A healthy root system means a healthy plant and propagation cubes can be used with even the most fragile cultures.
