i found placing a wet ( not soaking wet) but damp paper towel on the eggs will help a little, since the towel will wick up mositure and the eggs can asorb some from the towel. another trick I use ( takes a few days to do this ) was place a heating pad on low under the hobuvator and have the mixure wet (with a light disffure on top to prevent the eggs from making direct contact with the wet verm) this produces a lot more humidtiy for me. I had ot tilt the lid at an angle to keep the condisation off the eggs ( reason I place a paper towel on top and check it often ) I also had to add water every so often ot keep it from drying out. ( right now I got mine set up on the desk and it run dry 3 times in the last 2 months while waiting for the eggs to be laid this year.
