selaginella Kraussiana dying
I have an established tropical terrarium, 80deg, 70%humidity and it gets misted lightly daily. Lighting is two CPF 23watts each(equiv 60w x 2) Substrate is coir fiber/tree fern fiber with drainage gravel. All is growing well including jewel orchids, rabbits fern, pepperomia, amazonica. I planted a quarter sized s. kraussiana and in a week most of it wilted, now only one green branch is left. I misted it and poured some water next to the plant to keep it moist with r/o water. No fungus or mold.
What happened? You cant kill selaginella with these conditions??
