I have a havobator genisis and it has a fan in it. With the plug humidity is 63% and temp staying around 99.5 - 99.7. Do I still need to remove the plug for them to dry? They started hatching this morning but I have several that have no started hatching not sure about the vent plug. The first one hatched around 8:30 this morning and it almost dry as of 1 pm.
