I have a 3 year old + cephalotus that has been dying back a lot. I keep it in a 10 gallon tank exactly 9 inches from 2 florescent tubes. It gets a little sun every now and then. I keep it on a tray of wet soil and keep soaking that soil so the plant gets water from that. The top of the tank has a piece of glass over it to keep the humidity up. The gap between the glass and the sides of the tank it about 2 and a half inches on both sides.
It's not happy.
Any comments are welcome! Thanks! Some pics...
Proof that I grow other cephalotus well (pic taken today):
And proof that these Ventricosa hybrids look cool
