Thanks! Burmannii is growing so quickly. For my sphagnum, I don't use any media. I grow it by itself. Put it in a tray you that allows it to cover the entire bottom with an inch or two of live sphag to prevent drying out. I keep the water level right under the moss heads, when the culture is starting up.the sundews are looking awesome. What medium do you use for the sphagnum, I'm thinking about starting my own culture. Thanks.
