I have to ask, how long before the stuff takes off? I have gotten some to start growing on a couple different occasions. This last time it has finally stuck, but I'm still not seeing the weed-like growth everyone else talks about.
I have a little in my outdoor bog container, some in a terrarium with my neps. Even a miniature variety that hitch-hiked in with a trade, (thanks!) that I thought was lost for a little bit. All of it has been showing new growth over the past year, but nothing spectacular. My red N. Albo is growing faster than this stuff!
Does it just need to reach some certain critical mass before it explodes with growth? Looking at nature, it should be harder to grow the cps then the substrate they live in right?
