I would risk it. Use warmer water on the sponge so that it compensates for the time the bator is open. What I do is have the sponge under one of my vent openings. I place a straw in the vent opening and then use a syringe to add water if the humidity starts dropping.Did I read somewhere that the temps are supposed to be a bit lower during the hatch? Does that mean the whole lockdown, or just when they start to pip?
My darn bator insists on running high, no matter how low I turn it.....
I thought ahead to buy a sponge, but forgot to put it in the bator at lockdown. I'm struggling to get my humidity up. I ran it in the thirties for the 18 days, now I can only get it up to 54%. Is that enough, or should I risk opening the bator long enough to toss in a wet sponge?
