How many reeds should I put in a diffuser, and what factors should influence this decision? Is there a specific number that achieves an optimal fragrance diffusion, or does it vary based on the size of the room and the potency of the essential oils used? If I choose too few reeds, will the scent fail to permeate the space effectively, leaving the atmosphere lackluster and uninspired? Conversely, if I utilize an excessive number of reeds, could this lead to an overwhelming olfactory experience, perhaps causing discomfort rather than creating a soothing ambiance? Moreover, how does the material and thickness of the reeds affect the rate at which the fragrance disperses into the air? Might different types or brands of diffusers also play a pivotal role in determining the ideal quantity of reeds necessary for achieving a harmonious balance of aroma? What are the nuances involved in this seemingly simple act of scenting a space?
