those of you using a humidifier, does it run constantly ?

using a mister, i.e. cold water, does not last

I turned on the water and let it run for about an hour
the RH went up from 40% to 70%
the temperature went down from 77 to 71

I turned it off because it was getting into the afternoon and the plants were all wet
the RH went down from 70% to 50% in one hour
the temperature went up from 70 to 73

I turned it back on because the humidity was so low
the RH went up from 50% to 77%
the temperature went down from 68 to 60

It has now been off for 2 hours and the
the RH went down from 77% to 60%
the temperature went up from 61 to 62

It would have to be on most of the time to have a RH in the 70s

outside it is 40 degrees and 80% RH
