Ultrasonic humidifier, maybe? No clue if it will help!

I looked those up and I don't think that is what it was. The fog it emitted looked like dry ice fog. And it was tiny. About as big as a saucer.

It's just called a fogger. People don't usually use humidifiers anymore 'cause you have to keep putting water in them. There are really old ones that you can fix up if you can find one on ebay or something.

Actually the new ones are called hydrofoggers I found out but they're expensive. I'd get one if I had a greenhouse. They have a fan that chops up the water-droplets and blows them into the air. Kinda cool- I watched a video.

I looked up hydrofogger on You Tube and I think I found what I am looking for. It's called a mist maker. Anyone have any experience with these?

The one I saw used at a show was inside a Wardian case housing cool growers. I am wondering if they are practical for everyday use or just for show. Any thoughts?

All of these cool-mist humidifiers use ultrasonic disks to generate 5-10 micron sized water droplets. The higher the output, the longer the mist sticks around. Very different from dry-ice foggers, which rely on sublimation of solid carbon dioxide, and are essentially just for show, aka useless for humidity.

The ultrasonic humidifiers are definitely useful for increasing humidity in small enclosures, as they provide humidity in addition to lowering temperatures somewhat. However, in a large room, I suspect the effect will be very minimal.

They can be purchased as full units with water reservoirs, or as individual disks. I prefer the full units because the disks require you to supply your own water container, and water usually splutters everywhere. With the full units, a fan is usually built in, which assists in spraying out the fog in a stream.

Most home hardware stores will cary these units (look for cold-mist humidifiers). There are also several terrarium companies that supply them (ecoterra, etc...). Finally, there are industrial sized units for greenhouses which are much more expensive, but produce an incredible amount of fog. Mainlandmart sells some units for around $500 bucks.

Hope that helps!

I found out that there is such a thing as fogponics. It doesn't usually involve any potting medium though. Plus you need to add some kind of nutrients to the fog.
