Humidity problem?

im going to use a large cardboard box with holes cut in it and a CPU fan for ventalation. i pretty much have everything set up for when my 1 plant is ready its just the only place i can dry it is in my basement and even with a dehumidifier it still stays a constant 68-70% humidity and at abot 68-72 degrees F. my question is is there anything i can put in my dry box to draw the moisture out of the air inside the box or atleast try and capture some of it, or will 68-70% humidity not cause me a problem with mold..any help would be great..thanks

Do you have a fan to circulate the air? If not, add a fan to the box and that should drop your humidity in that box. Not sure how much, but it will help. Also AC draws moisture out and drops humidity (if that's possible for ya).

yes i have a CPU hardrive fan thats in it
