I cut clone and veg all in 18/6 light. So cut scrape dip and put ur cut in your rockwool. U can put it directly into soil from there if u want. Just dont over water your wool and soil. Ph ur water to 5.8. Get the wool damp useing the already explained a million times process or soak blah blah blah.. Just keep in mind rockwool only needs about a tablespoon of water per day and that totally sufficient enuff to root clones. Some people dont even water them after the initial presoak. Hope this helps.
