For quite a number of months, my merriliana and my northiana aren't increasing in size....
They're supposed to be easy growers I know....
All the other Neps in this lowland tank grow really well (bical, rafflesiana, belii, truncata, longifolia, adnata, ampullaria, mirabilis) (I currently grow almost 40 different Nep species)
It shouldn't be the light, because my system has worked really well for years. The humidity level is about 90 %.
Should I maybe repot them ?
To people who grow these species : what medium do you use ?
(I can get coco fibers, peat, sphagnum moss, perlite, ceramis...)
