I have just been using the hydrometer that came on it I dumped all the water and it went down to 30% so I added about a syringe of wafer. I should just dump that out and put how much water on lockdown dayWhat are you using to measure humidity? Many of those instruments are notoriously inaccurate. As long as you have all the water out I think you can go ahead and start your eggs. Dry hatching seems to work really well here in Oklahoma, you only need to add water at lockdown (day 18).
