Two or three years ago, I saw little ultrasonic humidifiers in our
local garden centre. They weren't intended for use specifically in
mist propagators, but did produce a sort of fine fog of water
droplets, and were meant for generally raising the humidity in
conservatories or other rooms that might suffer from low humidity. One
of these operated intermittent using a timer might do for you. Google
for ultrasonic humidifier and lots appear, at around GBP 30. Might be
something there that suits.

Problem is they almost all come with fancy lights.
