Lights off VPD?

With this grow that I just flipped to flower I’ve really been trying to dial in VPD. With the help from Ac Infinity 69 controller I was successful in dialing that in but my question is about lights off VPD. Is there a range that I should be shooting for while the girls are sleeping?

    Conditions in the room should stay the same day and night for best results.

    Best to shoot for at least half the ideal you are looking for. That will adjust due to humidity and stage of plant. Ideally you should see higher VPD in VEG than in Bloom.
