mid, how are you man.
Tops for cloning, sounds good buddy, you can double the amount of plants.
The fogger its a good deal and definitely helps pick up RH dramatically, but keep an eye on temps, don't let them get lower than 80F.
Looking at the size of your dome I'll suggest opening the dome every second day just for few min just enough for the air to get fresh.
In eight days they should start grabbing root.
Some times you can pick the RH in the dome by putting couple of inches of water in the tray of the dome.
As the water evaporates (cause of high temps) you get humidity.
Keep me posted on the progress buddy, and good luck with them tops.
