i keep the dome's vent closed until i see roots,yeah i open the dome once in a while for fresh air,and before i close the dome again i spray it with water (the dome not clones)
also have a heatpad on low settings..
rooting took 1-2weeks some cloned faster then others..
the clones from flowering plants can take up to 3+ weeks.
if you keep your humidity up you dont have to really water them everyday,though u shouldnt..
when they start rooting is when they demand water.
