Growool, rockwool, Propagation Cube, 35 x 35 x 40mm, Unwrapped, 21 cubes
New Growool - rockwool is for Hydroponics and propagation. Ithas very good aeration and allows fast crop turnover and minimum plant stress. It is made from molten rock spun into cotton candy-like fibers and then compressed in to slab. It has a special fiber structure which provides a block with less density for the roots to grow through much easier while still retaining the block’s strength. It fit into common propagation trays and may be transferred as needed to blocks or traditional planters.
