Humidity at lockdown should be.........(fill in the blank)

[Hennypen]

I must have messed something up during my last hatch to have gotten as many bloody umbilicals as I did. The humidity level was at 70% the whole time dropping down to 65% a few times when the water level got low.

So, what SHOULD it be?

what happened.and did you calibrate your hydrometer?
I did not first hatch and when I did found it was way off.

Mine was 70% - 75% (when hatching was going on) with no problems so i really do not know.

I like to keep it as near to 65% as I can get. Do be sure to calibrate your hygrometer as it is very common for them to be off.

65

I shoot for 75% at lockdown and as soon as I see the first pip I throw an extra wet sponge in and try to keep it at 85+% until they're all out.
