I also have a VE-2 and am having humidity adventures. What I've done is, butcher paper for substrate, smaller water bowl with less water in it, holes for circulation and a fan angled towards the rack. The fan makes all the difference, dropping the humidity from 96% to about 75%. Things still climb to to high 90's when someone urinates, but I haven't had a problem with condensation on the sides since enlisting the fan. I hope this helps.
