I was recently told by someone in the know (on this forum) to be sure not to bury the bulb too deep, much like anubias, keeping a fair amount out of the substrate. You prolly know as much. My red tiger l. is my very favorite color in the tank and is starting to slowly grow quite a few leaves. I think folks trim them abit to keep from taking over the tank. Mine just had one skinny start shoot when it arrived from AP.com
Good luck. bob
