Never used rock wool before, heard I should soak it, what's would be best way for me? I'm coming from soil clone in brown clone plug going from clone dome to the rock wool dwc, my buddy said 400-500ppm nutes from the gate?
I never soaked mine but a lot of people do, they use 5.8 ph water for 24 hours I guess never had a problem with just straight running but I was in a ebb and flow so the rockwool got hit with nute solution 5 times a day so if I was u I would soak in water first since ur doing dwc
