I have humidifiers in both my tents. They're operated by controllers--an Ink Bird and an AC Infinity.
I've noticed that humidifiers apparently are only needed when the plants are small and in small pots. As they grow, they provide their own humidity. I noticed this because I gradually refill the humidifier tanks less often as the plants get bigger, yet the relative humidity in the tent stays almost the same, except it increases noticeably after watering. Eventually, I vent the tent to reduce the humidity supplied by the plants.
I have a dehumidifier in my lung room that I use during late vegetation and flowering. All my plants are in vegetation right now, so I have my RH set to 65% and the temperature set to 77F. At those settings, the VPD should be 1.0, according to the chart I'm using.
