If smelling your house up is not a concern, any closet or enclosed area with a fan will work for drying!
Optimal RH% for your home should be between 45% at the lowest and 55% at the highest. Temps should be in the 65°-75°f range as well. You also want a fan running to circulate the air but you do not want the fan blowing air on the plants at all. The goal is to not have stagnant air but also not a hurricane blowing your plants around!
If drying in your home is not an option due to smell (my situation, wife hates the smell and I own a condo so my neighbor can smell it through the walls at times) so I had to purchase something that properly dried buds while keeping smells out.
The solution I found was the “WeDryer” XL version. This is like a normal drying rack but with a fan and a carbon filter attached for steady air movement, slow drying and odor scrubbing.” I have dried up to half a pound in this thing without anybody knowing! It also keeps the buds looking amazing!
