Ferns are a great choice for lower lit rooms. They require more water including regular misting but they are very beautiful delicate houseplants.
Consider choosing nylon as your string option for ferns- The amount of water ferns need mean the string can break down quicker so nylon is a safer option if hanging. The sphagnum moss also goes beautiful and green over time, which your will see better with nylon string. Just choose 'Nylon' as a string colour option.
