Thanks wolfn, swords. It's just that I'm a little worried since this is my first highlander. By the way, I do plan on growing it in a cooling chamber (can you say glorified icebox?) during summer, seeing as it gets to be around 90-100+ F around here , and above 70 at night. (Yeah, I know, my raff will go nuts.) Even in the house it still stays at a steady mid 80s during the day and 70+ at night.
However, for now, I can put it off somewhat and just grow it as a windowsill plant for the winter. The night temps are hovering at around 59-60 on the windowsill and about 49-50 outside.
BTW: Is singalana really as slow as everyone says it is? I hope not! (Seeing as I accidentally plucked of a tiny piece of root.)
EDIT: Whoops, I read my thermometer wrong. It was actually 49F! I didn't know it could get that cold in San Diego (on a windowsill). The window was only about 6 in open! I closed the window after I read that it could get to 39F tonight! (Don't wanna freeze my plants, especially the raff on the same grow rack.
