I’m currently on the day of the switch to flowering and want some of your input on one slight issue I have.
Last grow I had a bunch of issues due to mold growing in the buds I presume due to high humidity and now enough airflow.
So this is the dilemma, I live in a quite humid country averaging 80% on a daily basis, and in my tent averaging 65% on a daily basis and I wish to keep it at 45% constant.
This is the problem I have, if I turn on the intake fan (outside air) the humidity will always be high in the range of 75% so I turn it off during flowering and only have the extractor running (it’s running 24/7 from the beginning of the grow) , if I turn on the dehumidifier it will help goes down to 60% but heat will go up since its the byproduct of the unit, I also have a portable a/c unit bought specifically for the plants but still the humidity refuses to go below 55%.
Currently I have 2 fans running on full speed to keep the air circulating, I DEFINETLY don’t want to deal with mold again in this one as I lost a lot of buds due to my stupid mistakes.
Are there some options which helped you keep the humidity as low as possible?
