New to the Forum, Not to Orchids

I have been growing orchids for thirty years. One would wonder why I still have orchid problems. I grow in a greenhouse in Northern California. I run my house between 60 and 80 degrees as far as possible. I use humidifiers to keep the humidity around 50 to 70%. I grow species and hybrids. Our season here is winding down and I am preparing to reduce watering on the Dendrobiums and prepare for the cycnoches to bloom. My question is about getting the kikis on my Annosum to start life on their own. I have waited for good roots and them planted them in the media of the mother plan and they never seem to take off. Should I cut the stem that the kikis are on and lay on sphagnum moss and try to get them going? Any tried and true methods would be appreciated
