I have 2 bowls of water with sponges in them in two corners of the incubator and it's only bringing the humidity up to 62%. They are both under vents plus they are full. I also have a tube I can put into the reservoirs to fill them, they are both full. I put a humidifier in the room about an hour ago and now the humidity is up to 64%. Hopefully it will go a lot more.
