Where do you have your vent set at if hatching in the Brinsea Octagon Eco 20? I have that cheap wal-mart hygrometer in there and I do not trust it...at all.. .. I have the vent open about 75% and I am still getting like a 50% humidity reading.. (well 40%, but when I calibrated it, it said it was off 10 degrees). And sometimes the temp on wal-mart's one stays consistent at 99.6, then all of a sudden it will say 97 degrees, but the one that came with the incubator hasn't changed. I'm sure the wal-mart one is in the wrong. However, I'm getting worried about the humidity aspect of it. Please tell me where you keep your vent at approximately. Our house is not very humid since we have central air. And, I have one channel filled w/ water. Thanks in advance!
