Salt on a baking sheet to level out humidity...???

Growing in a basement in the rockies.Humidity is pushing 75...need some tricks to bring it down....50-60%???

I got these little buckets from the grocery store called "Damp-Rid" and they sell refillable material for it once it goes away. 2 in a big double sliding door closet got the humidity down from 75% to down in the 60% area.

More fans or ventilation in/out of the room, would be your best bet.

a dehumidifier or a small air conditioner. that's all i can think of.
