How do you set up the Hinoki Eucalyptus Scent Collection diffuser, and how many reeds are recommended for a medium sized room?

To set it up, place the reeds in the Hinoki diffuser bottle and allow 24-36 hours for the fragrance to diffuse; for a medium sized room, use 5 reeds. It comes with 7 rattan reeds. You can use more or fewer reeds to adjust the fragrance strength. If the fragrance dissipates, flip the reeds. Using more or fewer reeds will affect how quickly the liquid evaporates.
