Ive had this "mother" java fern in my 30 gallon for quite some time now. I always attached the plantlets it produced to drift wood and rocks, until just now. Attaching the tiny plants gets really annoying....they either slip away and go into the filter or a fish rips them of. So now, I got the idea that I could put them in a cup (filled with water from the tank) and place them on a windowsill that gets a moderate amount of light during the day. Have any of you done this? Can it work or will it kill all my babies?
