Relative newbie here but I got my first humidor. Did all the seasoning steps, and it was huming along at 68% RH for a week or so, now going into week two it wont get above 63% RH (outside is only 59% or so). The meter is fine. I have added more water to the sponge and it doesnt seem to be doing anything to bring the RH higher. Ideas? Is there something I am missing.

Thanks,
