Rh I need a really smart person

[TripsRabbit]

Why does my rh in my tent drop by 20% when I unplug my dehuey?

Lol huh? Not supposed to work like that.
Give us more details.

Two hygrometers, both reading mid to high 50s rh and I have a scrubber and fan on the 4x4 tent venting into the same room. There is a small dehumidifier outside the tent that struggles to keep the rhbelow 55 in the tent and keeps it around 50 outside the tent.
As soon as I unplug the dehuey the rh in the tent drops to around 40% and slowly rises to around 45%...
I'm perplexed

 

[Dirtbag]

Not sure man, that defies logic. Does the temperature change with it unplugged or plugged in? A dehu besides removing moisture also releases a lot of heat, which also typically lowers RH since the air can hold more moisture.

What does your hygrometer rh say outside your house..
When is it happening lights on or lights off

So, the dehumidifier is acting like a humidifier? If the humidity is low, why are you turning on the dehumidifier?

 

[paradoxlsot]

I would say by adding humidity to the air you're surpressing evaporation from the soil. And then when you turn the dehumidifier off, it drops, and then rises, as that's the lag it takes for the specific heat to get transferred to latent heat.

I have a theory. The humidity must have been dropping when I turned off the dehuey. I tried it again and my humidity went up this time.
