Water plant Cultivation Ceramics are a different, direct and easier form to place rootless plants in the aquarium, saving the hard work in tying them up to rocks, wood etc. Just put a little amount of these plants directly over the ceramic plate, covering it with the metallic screen. All the mosses and other rootless plants may be used, like Java Moss (Taxiphyllum barbieri) or Crystalwort (Riccia fluitans) INSTRUCTIONS Lift the 4 hooks on the corners of water cultivation and also remove the stainless metal net. Put the moss on the cultivation and trim it nicely by following the shape of cultivation. Put back the stainless net and 4 hooks. And after that, you can put the whole set in the water.
