My clutch of eggs are at day 31, and while checking them last night I noticed they appear to be dimpling a bit early. Incubation medium is glazed coarse vermiculite, on a diffuser, with press and seal under the lid. No airholes, just venting the tub every week. Incubation temp at 89.0f - 89.8f. by ZM thermometer in the tub itself. Humidity at 95% - 99% I always thought dimpling early on in incubation was due to the humidity being too low?

Condensation visible above substrate? Sorry for the poor lighting on the second pic. Will repost next week.
