Humidor Question

I recently bought my first electric humidor. Received it Sunday, filled it with water, plugged it up and have been waiting. My question is, how long should I expect to be a “normal” break in time for the humidor to achieve the desired humidity and temp (this one does both)? I’m currently sitting at 67 degrees with a 73-74% RH. I’m looking to get it to 68 temp with a 68% RH. I’ve seen anything from 2 hours to 3 days. Looking for some feedback from folks that have gone through this before.
