I have a ten gallon aquarium that I put play sand in. I than add just enough water that there was a thin layer of water above the sand. I then added a lot of flourish to the water and sand and mixed it up. I put a glass lid on the top and then put 2 23 watt CFL (6,5000k) above the tank. Will some plants grow quicker immersed.
You really only need to worry about leaf die off on the stems since they actually have two different growth forms the anubias and java fern are rheophytic and the leaves are the same in both forms. You will see some hardening of the leaves in the emersed set up to account for lower moister but if you keep the humidity high won't be the case
