How do I get my humidity down?

The cheapest way is to use rock salt inside grow space. (I remember my grandparents used rock salt between double windows on winter to prevent fogging.) -Drill several small holes in one of the buckets along the sides and the bottom. -Put the bucket with the holes inside the other bucket. -Fill the bucket to the top with rock salt. -Place the bucket in the area of your home you'd like to dehumidify. -The bucket will begin to collect water, and that water will drip through the holes of the inside bucket. -The water will then collect inside the outer bucket, trapping excess moisture.
