i like to dip the cube in water/light b1 solution at transplant(I don't use rockwool anymore, but when i used to--plus getting cuttings from dispensaries.) make sure you're soil is adequately watered, it can suck the water out of the cube and wilt the plant. just something to think about if you notice anything like that. even if the soil appears to be wet the cube can be in there dry as a bone. I switched to jiffy pellets like 10yrs ago and never looked back.
