Question for you about curing

So I get home from work and after awhile I open my jars. I don't put the lids back on them till morning just before I leave the house. My question is if this is too long with the lid off. The lids are off approximantly 13 hours, is that too long without the lids on?

It'll be fine.

It depends on how moist the bud is when the 13 hours starts and how much bud is in the jar. You might wake up to the top buds being too dry and the ones at the bottom too wet.

Depends how far into curing you are, in the beginning buds generally need more "air time" than 1 week into curing.
13 hours could adversely affect the buds but it depends on the rooms RH, temp, ventilation etc.
