Hey my rh is currently 60% mid day and 75% lights off. I am looking at a dehumidifier but upon reading the details about it the operating temprature is 35°c max wont this damage bud growth if used in flower.im going to buy a new fan for lower canopy and two clip ons for upper canopy I'm trying to prevent bud rot will the fans be enough or do I have to use a dehumidifier

Only thing I can say mate is constant air flow and extraction you should be ok for 1st part from what I know bud rot strikes before the end most the time .i have tried numerous things to decrease it and only thing I know that will work would be buying a dehumidifier if you got the money that be the way to go.sorry I don't have more Information mate

An issue with too high of humidity late in flower is bud mold. As the planats get closer to being done, actually put off a lot of moisture that raises it as well.

My tent sits in my office. I use a dehumidifier in my office, not inside the tent. Works great for me year round.

Its very important to keep the humidity down, you dont want any type of airbourne molds hangin around. The environmental conditions for mold include temps 65-70f and humid and spread within 3-5 hours in ideal temps and moisture conditions
