Obviously humidifiers put out humid air, but are they actually designed to run in very humid air?




common sense would denote that yes they are but i could be wrong.

actually they're not designed to operate in super-humid environments, but the UL does have really stringent requirements for any device that consumes electricity and houses water at the same time...so you'll likely not have an issue.

my greenhouses will run from 95-100% humidity at all times.
the unit (coolmist) sits right in the greenhouse, on top of some perlite.
they run on a timer, and are on about 15% of the time overall.

no issues.

having tubes connected to your coolmist is a much bigger threat
to it then setting it inside of a greenhouse to run. I burned out
about 6-7 of them piping them in from the outside. Even having
two pipes per unit.

That's because the cheapo muffin-fan impeller they use cannot handle _any_ static (back) pressure...and the very nature of hooking up hoses and such causes the static pressure to rise on the fan and it just grinds itself until it burns out.

I never used a store-bought humidifier for automation, I happened upon agar's 20-gallon barrel humidifer tek and was inspired, lol. The blower that powers my humidifier is rated at 70 CFM @ 0.00" static pressure and 25 CFM @ 0.50" static pressure... ;-p

This is where I have to interject. There is more than one way to skin a cat. I came up with a tek to convert an incubating chamber into a fruiting chamber.http://www.shroomery.org/forums/showflat.php/Number/7282925#7282925

Bottom line is that the system has to be outside of the system.

randomly, and only because my mini-rant doesn't warrant any real thread because it's so++ off topic...

but I wish they still did that random-assed point system _and_ they had some kind of reward for organizing and commenting all the images in your gallery. I got absolutely not one lick of work done today but my gallery is so fresh and so clean, lol...

It is impossible to have over 100% humidity in air. Impeller-type cool mists can operate in 100% humidity. You will, however, need to find a way to provide fae (this can be done by simply leaving it partially open or creating holes/slits). Ultrasonics humidifier units are NOT designed to run in high-humidity environments, and will fail quickly if placed in them. The fogger itself, however, can run in these environments (it's submerged anyways). Evaporative (wick) cool mists may operate in 100% humidity, since most of the circuitry is usually sealed air-tight in the unit. These humidifiers aren't very effective, though.

well my input is i have a 50$ vicks ultrasonic in my sealed greenhouse and the whole greenhouse is sealed except for the bottom(which has a rubbermaid bin to catch the drips) and the humidity stays between 90-100% i have the unit run for 30minutes then off for a hour.. the 1.2 gallon tank it has lasts about 4days.. and ive had it this way for over a month now and have had absolutely no problems.. and i can say that the unit itself gets alot of condensation on it, just hook it up to a gfi outlet or a surgebar it would trip either before your house ever burn down.. i doubt anything would ever happen all the electrical is sealed in a water tight base hence you fill the "unit" with water i'd presume its moisture safe. i stupidly bought one of those "holmes wick style cool mist" didnt do shit for the humidity even running 24-7 it couldnt keep my greenhoue higher then like 75%... all im sayin really is a ultrasonic hudifier can withstand HIGH humidity, a wick style cool mist uses a fan with and an exposed electrical motor to power that fan.. i would presume that if any condensation were perspire onto the "warm fan motor" ya you would short the fan motor out but it still wouldnt burn your house down.. at the same time though both styles of units are designed to produce humidity which means most likely they can withstand alot of moisture... figure it this way parts of the world stay at or around 80-90% humidity and they still sell these units there so it must be able to withstand humidity..

The inside of a cool mist type humidifier is always at 100% humidity because of all the mist flying around in there. You can run a cool mist, such as the vicks kaz models inside the greenhouse without problems. I've done so for years and wouldn't recommend something that wasn't safe. I'm an electrical engineer, as well as licensed journeyman electrician, so am qualified to make that determination.

There is no reason to run any other electrical device inside a greenhouse. The timer(s) should be located outside the greenhouse. Computer fans are made for computers, which stay dry. They're not suitable for a high humidity environment the way humidifiers are.
