Soil depends on the species but Borneo/Indonesia types it would be 30% Peat, 30% Sand, 30% Beech leave soil, 10% Beech leaves@tigertim , what kind of soil are you using for Crypts? What humidity they require?
What are those noritoi and longicauda species demands in submerged culture? Is it difficult?
Like a Rotala spp. flower, but they are both Lythraceae genera.I only realised this was in flower because I spotted pollen on the desk.
