I've had my U. humboltii for three weeks and I see no signs of life which is very frustating. My reni that I received just days befor has new leaves (although small) since I got it. Both plants are in an east facing window with added light by way of a cfl. The humbolt is growing in an undrained bowl in lfs and a top layer of living sm. I know they are slow growers, Am I just being to impatient? Thanks, Jack
