so once i have my cuttings into the presoaked rockwool and in the tray with the dome do i need to rewater the cubes or simply mist da leafs and keep the dome humid?
Both. Keep the rockwool cube moist, never let it dry out, and mist the leaves/dome to keep it humid and wet. Cloning is not hard, it's just a process, that you have to follow.
ok so i can jst use the mister to keep the cubes and the dome moist can i jst water with regular aged water or is a very weak diluted amount of vegetative fertilize recomended
Just water until they root. An exception to this would be a couple of drops of Superthrive or a Vitamin B1 product. Once they root, then start adding a diluted veg nute.
