Phalaenopsis Kuntrarti Rarashati

Phalaenopsis Kuntrarti Rarashati is a hybrid between Phal. equestris and Phal. venosa. I got this little 'chid with group of other phals from Kingfisher Orchids and just realized that I didn't file any of them here.
Still looks like a keiki, but has tiny flower spike started already. There is not much roots - just one aerial outside the pot and one long one inside the moss. It worries me a little, but other then that plant looks healthy. Hope it will grow some more roots...
