Weird little experiment that I performed, took a single stalk of xenia, that was attached to a chunk of LR placed this in my bio-cube and then left the lights off for 4 days. The xenia shrivelled up and wilted and was kinda laying on it's side, then I turned the lights back on and then it did the whole wilting and spreading thing (if you've seen this you'll know what I mean) and turned into 6 tiny frags
