I'm still hesitant on the Belem as it requires CO2 and Ferts for it to actually spread decently... It'll be as slower than the fissidens. But that's just what I'm guessing. Anyone got any experience growing 'Belem' without CO2 or water column fertilizing? The only source of ferts they would receive would be from the aquasoil.
I've already moistened the soil, just to give the bacteria a head start or start emersed as an option.
