you don't want your humidity above 40-45% 60% will definitely promote powdery mildew, and mold...possibly budrot
Jorge teaches on the side of caution, and also they don't want tyou to give up...LOL, because you cannot get % to 40.

when they say 40-60...they mean 60% is as high as you can go without stopping production. I would never run my flower room at 55-60 % NEVER!!!

Go to ebay and spend 80-90 bucks on a used or refurbished model. I did, and my humidity is a constant low 40's. get a 30 pint, with an external connection...so you can plumb drainage. If you cannot afford this then you cannot afford to grow. I am not being mean...I am saying in the end yield and quality will really take a beating, if you do not get your humidity under control. You will end up losing time and $$$ well above the cost of a de-humidifier. Peace

PS...For those of you who need Zandor to confirm this...He did...to me.

I almost forgot. you will continue to have problems if you don't get better ventilation. Something I didn't mention about dehumidifiers...They cause heat, just like the back of an AC unit, or a "frig". Peace
latewood Reviewed by latewood on . Closet Humidity I'm having problems...my lights turn off at 7am, and the temp drops some. Along with that, the humidity is going up to 60-70%...I'm starting to smell a stale moldy odor coming from the buds...I've looked into de humidifiers and have yet to find one that's reasonable for my budget at the moment. Is it my only option to lower humidity? Three girls 3 weeks into flower...I don't want to lose them now...or even later due to molding...:( Can someone give me a little bit more info about mold maybe? Rating: 5
