I've got at least four pips right now, although none have really started zipping yet. Humidity was at 70%, but it's dropped to 67% (I think probably because someone opened the window in the room - I just closed it). I have a sponge in there, and two wet washcloths that are in cups/jars in there, and both troughs filled in the bottom. I don't want to open the incubator for fear of shrink-wrapping them or dropping humidity further, but I wish the humidity were higher. What do I do? Is this high enough? Thank you!
