The mesh is 30cm long and 12.5cm high, I had enough for half of that at first so I started with 15cmx12.5cm, and it took about 3 weeks to fill in, then I stripted it out and doubled it to the current size of 30cmx12.5cm, and in two weeks its starting to fill up already.
It seems to grow pretty fast really. Have a look in my journal in the sig and you can see from the photos how it developed. I am considering expanding it to make a complete all at the back to cover everything.
Just need to find some more mesh to do that.
Just looked through your journal. Looks like hard work but worth it. Planning a rescape/ new scape in my tank and want to use a moss wall to hide the filter, but might use it on the back as well as my picture background is pretty crappy. Was thinking of either the christmas moss or weeping moss as they seem to have nicer texture, Maybe interspersed with riccia to give lighter colour in areas. Where did you get the mesh?
I used Riccia in the past and although it looks great and grows pretty well I wouldn't use it for a wall.
Riccia needs light and on the wall it will just simple rot away quicker and only the top of the wall grow properly.
But also when it gets thickers the part attached to the wall will just rot and it will just come off the wall, so you will end up having to reattach it all the time, I would go with moss for the wall.
The mesh I got it long time ago from ebay when I ordered a few other things from this seller:
