Hi, I got a number of plants that grow well emmersed, such as Crassula Helmsii, Hygrophila Corymbosa and Disfformis, Eleocharis Acicularis, Syngonium, Anubia Nana, Java Fern and Ceratopteris Thalictroides. With the exception of the Hygro's, the plants have been going for almost one month, the Crassula and Eleocharis have doubled in size; the Anubias have dropped all their leaves and new ones are starting up; Syngonium has multiplied and I had to split it into two other pots; the Java Fern has stopped growing, with his leaves turning black. The Indian Fern has spread like a mat. The Eleocharis acicularis have been kept confined to pots, otherwise it would take over. The Hygro's have been placed on the tank last week, and the leaves are still looking good. I have been misting it twice a day with my own NPK mixture, and so far so good.
