How open/closed is your vent hole on the brinsea octagon eco during lockdown and hatch?? I plan on keeping it all open but I will put a straw through it and have a sponge on the bottom so I could add water as necessary. Is that okay? Oh and for my last hatch, the first 2 days of lockdown had about 70% humidity but on the actual hatch date it was 50%. Is this common for you to have to open the bator during lockdown to up the humidity? Water doesnt last long in the bator! lol
