I have a pretty low humidity when lights is on at around 38%, but at night it can go up to 67%, is it a problem? I have thought about buying a dehumidifier but do i need it?

Hi @TheGreenFingers! We've all experienced high humidity at night, because when the lights are off the air remains wet and plants tend to sweat more at night. In a few words, yes it could become a problem, especially during late flowering when your buds are becoming fat & compact, there is a risk of mold/bud-rot. I was running through the same issue until I bought an electric dehumidifier. It's an investment (100~300$) but it will probably prevent your crop from rottening and save you months of hard labour. Plus, resin & terpenes tend to develop better in a low relative humidity environment, this is the other reason why we all want to decrease the RH during the late flowering stage. Hope this will help, keep us up-to-date and happy growing :facepunch:

It is normal to have an higher humidity during nightime but it is not good for your ladies and could lead to a but rot issue ( mold ). To low you humidity you can add an exhaust , you can use a fan blowing around your budsites or you can put a cheap dehumidifier in your tent :blush::v::skin-tone-3:

Do you have an exhaust fan set up and running already? If not that's a cheaper/easier/better solution.
