Nancy, yeah, I was thinking of it a bit like greywater too but our system is a closed system not anywhere close to where the coffee is. I don't want to dump it down the
shower either because it will stain the tile.
John, I was sorta thinking along those lines too. I was thinking of just dumping it in a water can until it was half full, adding water, and then watering with it but not sure if it is worth it.
