>Has anyone had good luck propogating Glossostigma?

Wonderlites (colour adjusted mercury vapour)). The plant was not growing in
mats, but trather like a stem plant - similar to a strand of E. tennellus that
is rooted at only one end.
The glossostigma was never growing strongly, although it did flower after it
broke the surface. Now, in its new home, with lots of light, lots of nutrients
both in the substrate and in the water, it is not growing at all. If anything
it is slowly dieing. I conclude from this that it prefers lower light levels,
perhaps a pH below 7.0, and good water movement.
