Bringing in warm air from upstairs to a colder space downstairs is likely to increase condensation, as the air cools and is unable to hold the same amount of moisture.
indeed, also upstaris air in actually colder but will have th esame effect with heaters active in the room, but still no more morning rain on table 2
cold air dense
make warmer less dense air hold more water by volume
we have a cannadri 210 pints a day unit that goes in tomorrow, night humidity has been ok, but def not opitmal
what im concerned about its the pints coming out of the ductinng when the lights come on
id rather have it condense and be removed during the night cycle then to leak onto tables plants first thing when the lights come on...crazy right
