I'm no gardener but about 3 years ago my daughter brought two tiny aloe vera plants home, they were both around two inches tall.
She put them on the window sill in the bathroom which is shaded ... they never get watered... but have grown like nothing on earth....they have since been re-potted twice and now need doing again.
So it appears the warm moist air/steam that they receive in the bathroom suits them, and no extra water at all.
