Humidity question

[Papapuff559]

So I'm in 2nd week of flowering and wondering about my humidity level. I'm lucky and don't really have a problem with excessive humidity but wondering if I should keep the humidity at a steady level or is it ok to have them fluctuate as long as they don't get too high. Right now, in any given 24 hr period, they're staying in the 40-51% range with temps ranging from 68°-77°

I'd love to have it that low! I've got stuff drying in 80% RH because of a stalled front that rained on us all week. I think they'll be fine as long as they have ventilation.

I've been super lucky with my first grow. During veg humidity was between 50-63 because of rains and now in flower they've been keeping in the 40-50 range without the need of a humidifier/dehumidifier

What kind of lighting are you using?
HID needs to run in the mid 70's because of the IR it emits.
Led needs a warmer room because of the lack of IR heating, so low 80's are better.
I try to use a VPD guide to help find what the RH needs to be for each stage of growth.
This has a lot of info if you're interested.
