    Humidity above 60 in flowering

    Hello,
    So yeah, I've been battling humidity for some time now and can't help it. It's 5 weeks old autoflower in 20l fabric pot, grow tent size is 60x60x80cm. The tent is located on second floor, above my bedroom, the staircase is open so no doors to isolate tent room. First I tried running a/c, didn't get much out of it, tried leaving tent door open when lights are on, it helps a little. Recently I bought a dehumidifier and it did help... a little. I thought the room is too much since it's open and moisture from below rises up too, so I got another today, but It's still holding 57-58. It's been really rainy those few days and will be for a week or so, what should I do? Opening window helps sometimes, but I can't leave it open unattended since if it starts raining it's gonna get worse.

    You might try going old school. When I bought my first home there was a water heater closet that was always humid and had a serious mildew smell. I put an open bag of charcoal briquets in there and it worked like a charm.

      If your room is unfinished, the moisture could be in the wood, keep the dehumidifier running to pull it out.
      Don't worry, be happy, grow sticky buds.

        Can you raise the temperature of either the tent or the room the tent is in? If you raise the temps a bit the RH will go down.

          I can, with A/C if it'll do.

              I'm adding humidity to get to the 70% range when the lights are on and mid 80fs right now for my flower girls. It's lights off I have a problem with high humidity.

                The humidity is about 3-4% lower going in than coming out. Going though the change in seasons here but none the less. I do have a small fan running and the flower tent always has the exhaust fan running at least on the slowest speed. Lucky to get the inside humidity below 65% with the summer/humidity levels here.
