Well I said I would keep you up dated on the TaNee.
Bad news I am afraid its on the way out
I have had it on the heat mat for a little over a month and its gone down hill quite rapidly.
I was cutting it back nearly every day due to the stem rotting back.
I decided to take it out of the pot and see what was happening and I found one single root.
Here is a picture of it cleaned up after I took it out of the pot.
