I added some plugs of live spagnum to my terrarium about 2 weeks ago. People complain about it being slow/hard to grow but mine grows very fast, and I love that. What I don't like, however, is the new growth on it. All the new growth is dark green, however it's still compact , so it is getting enough light,I guess. Why isn't it a nice lime green? It can't be the light, because my lights are almost 3x the power of normal flourescent lights, and because i collected it from an an area where it was growing in water in the dark (not litterly, but it was an extremely low-light environment) and it was light green then.
Humidity is always over 90 percent, soil is 2/1 ratio of sand and peat. i dont know if that matters.
