Adjust the amount of fragrance diffused by turning the reeds more or less frequently – 1-2 times per week or when you see dry reed tips.
For best results keep out of direct sunlight, heat and drafts, and ensure the lid is screwed on tightly. Flip the reeds as often or as little as you like depending on how much fragrance you’re after.
You may observe initial rapid evaporation of a Glasshouse Fragrance Diffuser, however this evaporation will slow down over time but the quality of the fragrance will not change.
