    Rockwool, How wet is too wet?

    You really only need less than 1/4 cup to dampen the 4" cubes. You can take the plastic off the cubes to dry faster but once dry only use fresh water for a bit because the water evaporates but the nutes stay. If you don't use fresh water you will get nute burn.
