Fully Saturate the Rockwool Growing Media Before Initial Use
To create the optimum air-water ratio during growth, it is essential to initially soak new substrates in a proper nutrient solution. If the substrate is not completely saturated to begin with, you are not maximizing its soil potential volume.
It is recommended to soak Multigrow Rockwool plugs, cubes, blocks and slabs in water with a pH of approximately 5.6 plus a nutrient solution. Use a pH down solution and a fertilizer designed for the crops you’re growing.
