I wouldn't. Once the moisture reaches a certain level it will condence on the substrate/walls/and any other object within the enclosure and create water build up in the substrate. Plus you don't want a level of humidity of 100%. It will begin to do this over an hour or so. You need something that automatically turns the fogger on and off when humidity reaches the desired level. Zoo Med Hygrotherm is one such device and is what I use for my Pacmans. You can even set it so it doesn't kick on when it drops 1% below the desired %. This device can control up to 1000 watts if equipment. It isn't cheap though, but not outrageously priced.

You hook the fogger up to a timer also to kick it on and off during the day at certain times or every so many minutes but isn't as accurate.
