DRYING IN GROW TENT 2X4 HUMIDIFIER AND DUCT 65%RH

Anyone here put a humi in their tent to boost the RH while running the duct with filter ? I have to keep the speed a med to get 65%rh but i dont know if its too high for drying. I also have a clip fan on the floor shooting in the corner to have indirect air flow and keep the moisture moving

65% Humidity is too high, you will get bud rot. lower it to about 50% Humidity and dry your weed for about 3 or 4 weeks

to get this i have ton play with my exhaust, does it affect the process even if keep it a 55%?
