Cool Mist humidifier or fogger?

[d0773d]

I have a ultrasonic fogger from thehouseofhydro. Should I use that or get a Coolmist humidifier? Any product recommentations?

I've tried both ultrasonic and cool mist humidifiers.
Ultrasonic types put out several times as much humidity.
Make sure you have a way to dissipate the fog without it blowing directly on plants.
I put a fan behind each ultrasonic humidifer, and blow the fog in thru upper tent portholes.
Then an oscillating fan inside the tent finishes the fog dissipation.

Aren't "ultrasonic foggers" and "Coolmist humidifiers" the same, just ultrasonic humidifiers, the other type being warm mist?

Over time, ultrasonic humidifiers leave dust, calcium and other salts, evaporated from the physically forced-out mist (unless you use RO, distilled, etc. low ppm/EC water). Warm mist models boil off the water, with the mist being pure sterile water, with no residue. If you need added warmth/heat and/or a 'purer' mist, go with a warm mist humidifier.

Yeah, basically. Sometimes, though, "ultrasonic fogger" is used to refer to products that are sold as just the ultrasonic element and a power supply, and you put the element in your own bowl / tank / container of water.

That House of Hydro one looks like just the element, and you put that in your own container / etc? There may be some splashing that you'll have to consider, but it'll work. You basically just need to balance the mist output with your ventilation / room conditions, your tank capacity with how often you want to be refilling it, your water type with how often you want to be cleaning/replacing the element, and have enough additional fans / circulating flow to help disperse the mist.

At 500 mL/hr, that fogger seems to be equivalent to a med-to-large sized humidifier.

I use these ones in a 2'x4' tent. My lung room has been about 40-50% RH. Not sure what my actual ventilation flow rate is, but I needed two of them during the first half of the grow. It doesn't list mist output, but says it should last 25 hrs on a 3L tank, so that would be about 120 mL/hr (240 mL/hr total).

The other consideration is control - If you are using a separate humidity controller, you want to make sure whatever you're using turns on automatically when it gets power. For humidifiers, that usually means looking for one with an analog control knob rather than a digital control panel (which usually need you to press a button to start it after it gets power). The built-in humidity sensor in most humidifiers usually isn't too accurate anyways, so it's usually better to go with a separate humidity controller regardless.

I suggest an evaporative humidifier like anything from Aircare but if you need to control your humidifier with a controller then I suggest a 4 gallon Vornado.

The larger tanks are really nice to have for efficiency and not constantly refilling, I hated having my humidifiers in the tents. Wasted a lot of time and energy coming in everyday to fill a 1 gallon or less that was constantly being exhausted back into the lung room.

I use a 6 gallon AIRCARE humidifier outside my tents that humidifies the whole room(14x20) to 55-60% and gets brought into the tents through the negative pressure of my exhaust. I've had it for several years now with RO water and an additive to help the filter last longer.

The house of hydro foggers are a waste of money imo. You need at least 6 for a 4x4 and at that price you could get any of the other two brands I've mentioned and have better luck.

@KDawg I've calibrated my humidifier against an inkbird controller using Boveda's humidity packs. The humidifier is over by 7% but the inkbird is low by 4%.

Yup. Evaporative humidifier all day.

Will this work?

The link is bad. I think it’s supposed to be:
