dojo you might be ok with those flouros as the plant and clones you see in my pics were all done under 2x14 watt cool white flouros in a carboard box!
keep the vents closed on your dome mostly but open now and again or even remove the lid for a bit,as for the misting i never misted the clones i just sprayed the inside of the dome with water a good few times a day as it can dry up quickly under the light so keep an eye on it.make sure the leaves of your clones aint touchin the sides of the dome as it happened with 1 of mine and the leaf is suffering a little,also try not to spray so much that the water will drip from the dome onto the clones below.if you soaked your rockwool over night you shouldnt have to worry about watering until they are rooted and ready for the pot.
i checked my WW tonight and i got myself a lady!!3 days on 12/12 and got the result i was after so the clones were worth doing.i took the clones 7-8 days before putting in flower. your clones might droop and wilt but they will spring back and head for the light in a day or 2.
take it easy man
