Hi, I'm using the Brinsea Octagon 20 incubator for the first time. I put my eggs in lockdown last night and I'm having a hard time maintaining the humidity level. I've filled both chambers with water and adjusted the vent and the humidity level still wasn't high enough, so I added a small, wet sponge. That did the trick and brought the humidity to 70%, but after doing that this morning, the humidity is dropping again this evening. Does anyone have any good tricks to keep the humidity high during lockdown? Thanks.
