I just put a couple Java Ferns into a tank at my grandmothers house. The plants have a lot of "starts" growing off of them and I am thinking about getting a 10 gallon tank set up just to start harvesting some of these to put into the 120 g I am going to start after new years. I was thinking sand my be better so the roots won't get attached to something and then I have to pull them out in a month or two. The two I got at LFS still have bunches of gravel from the tank they came from that the roots are holding on to. I tied them to some drift wood. What would be the best way to plant and raise a bunch of small java ferns that I could use in a few months? I was thinking about attaching some type of small weight to them and just holding them down to the substrate.
