I live in an area with relative humidity in the low 70's. I am currently in the 4th week of flowering and am thinking ahead towards the curing process. I've read that 50-60% is ideal for drying and anything higher will invite mold.

Will a fan solve this problem, or will that cause harsher smoking bud?

I know there are dehumidifiers, but I'd rather not invest any more money into my project.

Thanks for any input.
