Ive been wanting to to an emersed setup for a while now and i finally decided to start it. im using a bare 1.5g acrylic tank (tetra water wonders) and playsand as a substrate. the lighting will be an 18w cfl and sunlight from the window.
heres some pics. right now i still have them submerged and im gonna slowly lower the water level over time to let them adjust to emersed growth.
You'll probably want to add some type of root tab for the crypt, since they're heavy root feeders though. I'm very curious to see how this turns out. Legomaniac's journal has definitely piqued my interest in emersed setups.
