I just wanted to share that I have 2 Angraecum didieri in bloom as well as an Aerangis punctata. These are nocturnally fragrant. When the in tank exhaust fan kicks on it sends such a "heady" fragrance that we can smell it clearly upstairs (the tank is in the basement). It is actually too strong in th tank, so the best way to enjoy the rather sweet fragrance is at a distance
