He means that he has a powerstrip timer that turns the Monsoon off at night while the Cham sleeps. The powerstrip timer put power back to the Monsoon in the morning and then it runs the Monsoon's timer/cycle as normal during the day.
I have the same set-up on my ExoTerra for my Geckos and its been great for the past 6 months (just dont let it run dry).. I have to admit that the luxury of not having to worry about misting is great (especially going from hand misting).
Here is mine. I also find that it produces the best "mist" when using less nozzles. If you are going to be running more than 2 nozzles i'd say invest in a a system with a better/more powerful pump like AquaZamp or MistKing
