Good idea but i have only gravel and sand as substrate, and there is no water column ferts. I think that hairgrass cant grow in that environment.Very nice.
Have you thought about adding maybe one or two "sprigs" of dwarf hairgrass in the riccia?
Actually Riccia growing quite slow in this bowl (there is no CO2 and ferts). I usually get a trim every 2 weeks.Great scape. How hard is it to maintain? The space is so small, and the riccia grows pretty quickly no?
