Does anyone know any quick and easy methods to low...

Hi @Skunkman! I was running through similar issues with a 80% night RH and a 50% day RH, my room was overcrowded with big plants and the weather was rainy for weeks. The only reliable solution I found was to buy an electric dehumidifier (~120$), now I can precisely set my relative humidity because the engine is adjustable (from 30% to 90%) and I can ensure a frosty harvest without a chance of getting mold/bud-rot. It's some kind on investment to save your crop and even have better buds in the end (during flushing, the lower the RH, the frostier the plants gets). Hope this will help, keep us up-to-date and happy growing 👊

Make sure you have no standing water. Open up more ventilation to allow more airflow and turn up your exhaust if you can. Defoliate a bunch of the larger fan leaves and anything blocking bud sites. Also, make sure your exhaust is being pushed out a window so that the humidity being pulled away isn't brought back into the room the grow is in. If none of that makes a big difference get a dehumidifier and run it in the room you have the grow in so that the air going into the tent is at lower humidity. 60% isn't too bad as long as you have a few fans blowing through the canopy and defoliation will help increase airflow as well, reducing the chance of mold.
