i just finished building an incubator for a friend and I threw all the bells and whistles into this thing. One of the whistles is auto humidity. On my incubator I have a pan that a mister sits in with a cover and a humidity controller turns it on and off as needed. On the new incubator I added a holding tank and plumbed and actual system in for handelimg humidity. The pro - works great don't have to guess at humidity levels. The con. HOLY bleep! There's no way to clean this thing! So my question... Would adding a cap of vinegar to the water hurt his hatch rate? What would you use if not vinegar?
