I have never heard of this. So you think this would actually make a difference? Right now I have a 6l cold mist humidifier, but it does nothing to the room, or very minimal. I’m going to check this out.
In the meanwhile I thought of another option I will try. I will put my exhaust to 100% to lower the temp. The humidity will also be lower, but perhaps it will be more easily managable for the plants. At least they will get constant CO2 as well, which now they do not.
