just got my grow room.setup today. im using a really small concrete room in my basement. temps are 70-85 and i noticed the humidity is 70-80ish , but i havent put a fan in the room yet. will a small oscillating fan help lower humidity? will i def get mold or bud rot? the basement stays pretty damp from when it rains.
pretty sure circulating air can effect humidity, it causes evaporation. But fresh air will help drop it down. I dont think you will have problems with rot. They like it warm and alil humid. I keep it at 65-70h.
^^^^^^this. but if you are on a budget as long as you have enough air circulating and fresh air coming in, mold should not be an issue.
