Hi! It’s been fine thus far, about two months. It drips straight to the bottom soil if you put it in all the way, so no flies. Haven’t watered in those two months manually, so that’s the extent of me testing it! Just refill the reservoir and add nutrients when needed. Would highly recommend, once you find the right water cycle you never have to worry about it!
