Hey Len. Beautiful setup man. Keep it up.
I also have some questions. I have an emersed setup, and wanted to know how you are growing Java Fern in yours. I have mine in a tub of water in the setup. What I am wondering, is how much light you have over yours, what your water level is at, and how you fertilize it. Any help would be great, thank you.
P.S. If you need to see my setup, it is in my signature.
I just planted the java fern in rockwool and net pots, I set the rhizome on top of the rockwool with a couple roots in it to hold it down, it has since spread its roots and started shooting up new leaves, here are some pics. If this method works well, I'm going to try and obtain some harder to find varieties of java fern and grown them this way as well.
