    Default Help to bring down humidity

    Hello guys. I'm about to start flowering and I have a problem. RH is 60% with lights on but almost 80% with lights off. Of course I would like to bring it down to 40-50%

    I am extracting into the same room where my grow tent is (no possibility of extracting outside). RH in the room is always at around 65-70%, so I guess it wouldn't help much to buy a mini dehumidifier and install it in the grow tent, right? What are my options here?

    Thanks.

    a mini dehumidifier won't cut it mate, you want a 10L dehumidifier with continuous drain or you'll empty it 4x a day
    my dehumidifier sits in the room that supplies my tent with fresh air since i extract into the attic

    rooms rH is always 40%-45% with the dehu running 24/7

    Options are limited as, without a dehumidifier you will never get the RH below your rooms RH

    Options are to either reduce the RH in your room or reduce the RH in your tent.... Reducing it in your tent is the best option but will involve room that you may not have

    Thanks bro. Can you recommend me a decent dehumidifier that doesn't make too much noise (my grow tent is in my living room)?

    depends on your price range though mate, 10L Dehumidifier by Swan - Continuous Draining - Silent Mode - 24hr Timer - can set the humidity 35%-85%
    google SH5010N £115

    can get a more silent one but the price goes up also

    Thanks mate. As for the extraction thing, would I have any problem venting into the same room when flowering?

    not as long as it's running 24/7 and constant drain,
    they work wonders in flower, gets the humidity right down to as low as 35%
