So far I'm thinking a reed diffuser with something like pine or eucalyptus scent.
Peppermint, Mentha piperita: mood-elevating, has a positive effect on perception, memory, and other cognitive functions.
Lemon, Citrus limon: very uplifting, yet relaxing. Helpful in treating wounds, infections, and house cleaning and deodorizing
Rosemary, Rosmarinus officinalis: Very stimulating and uplifting, good to help mental stimulation as well as to stimulate the immune system.
Germanium, Pelargonium graveolens: helps to balance hormones in women, good for balancing the skin. Can be both relaxing and uplifting, as well as antidepressant

Well worth the maintenance load, and likely better for you than any artificial perfuming thing.
I like the lemongrass and there’s another one that smells like a fir tree..
