The Sprinkler is a nice mid-game item but is a little niche for what it offers, especially for the cost and the lack of synergizing with hydroponic basins and the like. Additionally, Odyssey's Grassland biomes have a "Drought" effect that can happen randomly that is basically a dry season, too little rain so the plants grow slower. It'd be cool to have the Sprinklers prevent Drought from affecting their growth speed on any plants in the range.
