Will High Humidity For One Night Cause Mold

Hey everyone, I need some help. I live over here in Colorado and currently have 2 plants at 8 weeks into flower and 2 plants in veg. The humidity here usually stays between 35% - 45%. I invested in a humidifier for the Veg side of my room to raise the humidity up to about 60% but last night the thing flooded and caused the humidity in the veg room to go to 100% and somehow leaked into the flower room and raised it up to 70%.

I have no idea how long they were in that high of a humidity but my question is how long does it take for mold to start growing. I have since dropped the humidity back to 40% so it was in there less than 12 hours my guess around 4-5 hours since it takes time to raise.

Also would you notice bud rot right away or could it show up a few days after this mishap?

These girls are so close to being done, I would hate to lose them now to an accidental humidity raise.

Oh yeah forgot to add that the air has plenty of air circulation, 2 large fans for 2 plants.

i would think you are ok for that short of a period of time. I had a mishap where my veg room ended up with extremely high humidity for 2 days straight and i started to notice some powdery mildew on some fan leaves down low. If you start to see those spots that I would say you need to think about possibly spraying, or in your case being 8 weeks into flower, i am not too sure what you would have to do. But for that short of a period of time, I would think you are going to be ok. Just dont let it happen again

High humidity for the life of the plant won't necessarily cause mold. It has a lot to do with genetics...where I live the annual average humidity is 85%

I'm outdoors and humidity at night climbs up to 80 to 90% routinely, then back down to between 10 to 50% during the day. I haven't had any problems at all. I'm in Nor Cal. I think day temps might have something to do with it. It gets pretty hot which drys the plants very well as soon as the sun comes out. I've never really seen much morning dew on my plants, and when I have it evaporates very fast.
