Each piece was cut to have 3-4 nodes when I planted it at start. I took the whole thing out a couple weeks ago to untangle the mess it created.
I replanted them again with 1 node this time. It has been a couple weeks since replanting.
Without the tangle mess, the leaves stay closer to substrate rather than hanging in the air. I looked at it closely today and it is starting tangle itself into a mess again.
It is the same setup as before, no fertilizer is added, not a closed system, and very little light (10 watt screw in PC).
I will take a photo of it tomorrow when I take photo of an outdoor emersed dome. I am experimenting the BC weather to see if I can grow swords outdoor. It looks okay so far; I will soon find out if new leaves are developing on them.
Next time I do a replant, I will take photos throughout the development.
Aaron: The largest leaves was 1/2 to 3/4" in diameter.
