Just to add, my Sedira japonica now officially has two spikes, not one. The new one is approx 1/2" long.
Ross, what are your growing conditions for your Sedir japonica? Mine is just growing roots and that is about it. Not sure if I should move it up more towards the lights or what? It is hanging next to one of the highest shelves.
And on another note, I will try and submit my status report this weekend.
