Humidifier dust on buds

I heard about similar problems, that cigarette dust is clogging up on the filters and then within a certain time they start to float in the air. The only way to change the filter regularly (once per 3-6 months, depends on filter type and model). But, I suppose if you'll start using humidifiers w/o filter, it may solve this issue. Click here, if somebody interested to learn more about such humidifiers. Feel free to share any experience with them, since I haven't got any ;/
 
First post here, also just coming off my first grow (Blue Dream, indoor, tent, had good guidance from experienced growers). Yet, I made the crucial mistake of having my humidifier inside the tent which is a cool misting model. I started seeing what looked like PM towards the late flowering stage.

The humidifier was necessary because I'm harvesting in a dry climate this time of year, thought i was being smart. Nope. Ended up with what I thought was PM in the final stretch but after seeing the buds continue to grow (and wiping away the fine dust it would disappear until i used the humidifier again) I was conflicted on what to do.

I ended up harvesting about 1 week early in fear that mold was going to take hold and ruin the crop. I wanted to try the Cervantes method of washing them. After doing this, I've still been very paranoid as a first time grower that I basically have nasty shit in it and shouldn't smoke it. Can someone verify if they've had this on their crop before and if it was okay for them to smoke? I want things to be okay but I'm not sure. However, I'm almost positive the white dust was not PM and instead this misting shit.
 
I had the same white dust about 3 weeks ago. It came from my cool mist humidifier the first time I used it. I'm on well water, it is just the vaporized calcium. Used distilled water every time after that and no more powder. At least I don't need any cal-mag.
 
I'm glad I came across this thread. I had what I thought was WPM on the walls of my tent behind my tower fan and behind the oscillating fan. Ive been going nuts looking up ways to clean and kill it. After reading this thread I believe its the mist/ vapor from my humidifier. It started right after I installed it. I keep it in my tent because the room that my tent is in has a pellet stove and I basically have 0 humidity. It gets super freaking dry in the big room and the tent is suffering because of it.
Is there any type of humidifiers that dont leave residue like these?
And on a good not my tent has been sterilized twice in the past week.. lol
 
If you are truly worried about this, I would recommend taking a sample of the buds and sending it in to a lab so you can be sure of what is on the buds and know for sure if it’s ok to smoke or not. That in my opinion is the best and for sure way to know.
 
Yea, PLreef, there are two types of humidifiers. One type will produce calcium dust unless you use distilled water. I wound up getting the other type and problem went away. Sorry but I don't recall the different types of humidifiers (that was a couple of years ago) but it's easy to look up online. Good luck!
