Lockdown day!(finally)/hovabator question....

[SomeChickinTN]

It's my first time incubating. We are finally at lockdown. I don't have a thing that measures humidity, and the hovabator says to fill up the second trough at lockdown. So that will be enough? When would I start seeing condensation?

It should be enough. I have never hatched with a hygrometer and almost never have humidity related issues.
