Humidity vs relative humidity

i wouldnt chalk that up to a humidity issue.
that plant is likley stunted out due to a grower error

I would totally agree with that assessment that was my trial grow in a new area, I guess I have work to do to dial it in properly, my temps dropped low to 51 degrees then jumped back up to 86 in a 24 hour period and I did a bit of pruning to expose the bud spots to more light, may have overdone it a bit as well.

She does have like 6 or 7 bud spots, I just hope they start to grow a bit, I haven't seen any stretching yet, but this is the first week of flowering, it should start stretching a bit soon right?

Humidity and relative humidity are the same thing, the amount of moisture air can hold is relative to its temperature.

From the link...
If the water vapor content stays the same and the temperature drops, the relative humidity increases. If the water vapor content stays the same and the temperature rises, the relative humidity decreases. This is because colder air doesn't require as much moisture to become saturated as warmer air...

As Star Dog says. You may have a humidity readin and a set point (roughly what humidity you want. Just like a thermostat. If you want 72 degrees set it for 72 degrees. One thing to not, humidity meters can easily be off by 5%, and it is no biggie.

My problem was humidity in the 30s, and my soil was drying out quick. I had to raise it, even wet sponges by the intake fan only got it up to 38-40, was starting to wonder if my hygrometer is working properly. There is an 11% point difference between readings, the humidifier is reading higher than the hygrometer.

That was my point. What your humidifier says is irrelevant, you want the room humidity to hit the target. How the humidifier is setup...how close to the intake, how much air circulation you have in the space and around the unit will determine why your room humdistat and humidifier humidistat are off.

If the room is lower than the humidifier, you dont have enough fan blowing at or around the humidifier. This will fix it 100%. Also where the humidifier is will greatly affect this. Unless you have multiple hygrometers in the room, you dont really know how good the circulation is. Same for temps, you want consistency.

Low humidity after 3 weeks of flower is good.
