I have java fern and observed that at lower light levels the plantlets seem to develp more frequently.. Is this true? I went from 1 wpg to 2.3 wpg and my java fern seemed to just grow and not make plantlets?
I'm not sure, but it's possible. I have rather low light and seem to get an awful lot of plantlets forming. Could be a cyclical thing too. A bunch seem to form all at once and then nothing for a while.
