It is certainly possible (probably easier ;-) to use Jave Moss in 
the manner decribed.  It would need to be trimmed more regularly 
since the plant produced longer "strings" than Riccia.  That said, 
if you really want to use Riccia, you should be able to find some. 
 Many hobbyists keep it, I have seen it on sales lists from time 
to time, and I have collected it in the wild in a number of

I know George really doesn't need any help defending either 
himself or Dupla, But before you accuse Dupla too strongly of 
"highway robbery", have you _compared_ fertilizers on a dose for 
dose basis?  Are you really sure that Dupla's fertilizers are more 
expensive for what you get?  I'm not, and I _have_ done some 
comparison shopping.

There is also no reason that anyone needs to use _everything_ that 
Dupla produces to be able to appreciate their products.  I don't 
use all their products because I can't afford them, but I 
certainly appreciate the R&D they have put into their total 
system.  I have seen far too many products on the market that have 
nothing more going for them but a testimonial from the developer 
saying, in essence, "it works for me!"<g>

_I_ can tell you George has no personal or financial ties to Dupla 
.(other than the fact that he has purchased some of their 
products)  J.P. Burleson is the sole U.S. distributor of Dupla
