Unpopular opinion: misting your indoor plants is basically useless

I spent 6 months religiously misting my calathea every morning because everyone says they need humidity. Finally bought a $12 hygrometer and realized my room was already at 50% humidity without any misting at all. Anyone else ditch the spray bottle and just use a pebble tray instead?

You say you bought a hygrometer and found out your room was already at 50% humidity. But what about people like me who live in a dry climate? My house sits at 30% most of the winter. I tried pebble trays for my ferns and they barely moved the needle. Did you ever test your setup by putting the hygrometer right next to the plant after misting versus across the room, because I'm wondering if the local effect matters even if the room level doesn't change much.

Honestly, I gotta push back a little here. That 50% reading from a single hygrometer doesn't tell the whole story because humidity can drop drastically right at the leaf surface, especially near a drafty window or a heating vent. Misting might only bump up local humidity for 15 minutes, sure, but for plants like calathea that are super sensitive, that brief spike can prevent leaf curl just enough. Pebble trays barely work in my experience unless you have a massive surface area evaporating, and even then a $12 hygrometer isn't exactly lab grade. Dry climate or not, if you mist right before the lights come on or the sun hits, that quick burst of moisture is way more targeted than any tray can manage.
