Hmm... Not so sure if the 3rd bud is going to do anything. I took the 2 pictures below to show how much the spike grows in 24 hours- 1/2 an inch. That seems fast to me. I've noticed that my delenatii seems to grow its spikes faster than phals or other paphs.
The spike has grown quite a bit more since the last picture was taken.
I just noticed today while watering that my Armeni White is spiking again.
It last flowered in September and then second spike in December but I accidently hit it and broke it right off.
This cross must be a free bloomer. I like it!
