Turning a Humidifier into a Mini Mister for Plants in My Room

Kurblius

Carnivore
I've one of those ultrasonic humidifiers I bought from Amazon for $60, that sends a cool jet of mist straight into the air. A couple weeks ago I realized I could turn it into a mister by bending a piece of plastic and then attaching it with blue climbing tape (normal tape just becomes unstuck with the humidity) to redirect the steam. Now my carnivorous plants get 70-80% humidity! I live in Ottawa so it gets pretty dry, especially in winter. My only concerns with this set up was:

1.) My cephalotus, which I know from experience doesn't like water directly on it's leaves, so I moved it further away.
2.) Causing the wall that the steam hits to rot or grow mold. So I covered that part with aluminum foil (which also enhaced the brightness of my growing area).
3.) Water condensing around my humidifier and forming an expanding pool. I put a tin tray underneath it, which now catches what I believe (?) is CP-safe distilled water. Can tin leach poison into the water in such a short time? That water isn't in contact with anything acidic, just water, wood, and air.

This humidifier has 3 settings, so I can set 3 different humidity levels (I usually pic the middle one). The humidifier itself creates air flow so I think I'm good on circulation despite the high humidity. It also helps cooling the air around my LED grow lights by a few degrees, which I THINK are all humid-tolerant bulbs, but I haven't checked (probably should but I hate disrupting my light set up). My maidenhair fern loves it, and I'm now thinking of buying some air plants to take advantage of the free humidity. I've read that air plants will rot if they are wet too long, but I figure if I position it on the edge of the steam it should be alright. Will have to experiment. I am also thinking of buying a low-light fishbone prayer plant to put in the tray beneath the humidifier with wicks bringing distilled water from the tray to the plant - apparently prayer plants, like CPs, also prefer distilled water, as chlorine and flouride will cause the edges of the leaves to burn. They also need humidity, which tendrils of mist from the humidifier should provide.

Not sure about LED's and mist or high humidity.
"Tin" tray. Do you mean aluminum? It will corrode and leak and leach minerals. Change to plastic.

Definitely Tin. Like the kind you buy with an assortment of cookies, usually with 2 levels separated by plastic holders and a piece of cardboard. I’ll keep my eyes out for plastic though.
 
I have bulbs of the same design (probably different brand) and they are fine in my lowland chamber which stays close to 99%RH all the time

I got one of those little top fill levoit humidifiers too! its not a bad little unit but the on/off switch is not solid state and it doesnt remember settings when the power turns off so i couldnt use it with an external humidistat. Are you just keeping it on all the time?

Can you explain what "solid state" means? I've never even thought of setting it with an external humidistat. I just leave it on all the time. Humidity reading around the plants getting the mist only changes if I open the window or use a fan to cool my room as it disrupts the airflow of the mists somewhat - I usually increase the setting from medium to high to compensate. Given that I only just started doing this, I don't know how it will behave come winter. It's also possible that it'll get too humid this summer, but I'll deal with that problem when it arises.
 
Sorry, i mean it IS solid state, not mechanical.
So when you press the on/off button on that humidifier, there is no mechanical movement, the switch is entirely electronic. So you cant just leave it in the "on" position and use something like an Inkbird humidistat to turn it on and off based on the humidity.
