I think the best way is attach it to a peat plate.
I am sorry if I offended. I re-read my 2 sentences. I typed a wrong word (is) . So my English is not perfect either.I've tried to help. Here we speak portuguese, so is expected my english is not perfect. Type your perfect english in Google and do it yourself.![]()
Why do you suspect Nobilis isn't a fully submerged form? I have some Star Moss I got from Aqm and it was in a very very thin peat base. After leaving this moss in a bowl with very little water for many weeks. I got brave and tied it to wood. It has not grown much but has greened up. I had sent some to a friend who has a high tech tank and his is showing the same growth rate but is much more green then mine.peat plate would be like coir fiber or a coconut mat.
I'm experimenting with Nobilis and suspect that it
first needs to establish and grows immersed, and
can survive submerged only after it's established.
Plagiomnium is suppose to be natural to my area. Here We call it badge moss. Have you grown it submersed? or started with it emersed. I guess I need to look for it.The last pic; if that is one that I sent you it was traded to me as a Plagiomnium species.
