Coelogynes with no flowers...

[Milda]

Hi.
I think I need some help. I have got several coelogynes, some are easy to flower, some are not. Just now I am a bit confused. I have had a lawrenceana for several years and it's happily growing in spaghnum, medium temperature, hanging under roof windows with some shade by summer. It grows a lot of new bulbs every year, but not a single flower in sight. I have read that it takes a long time for the plant from spike to flower, but I haven't seen any photos of such a spike.
The other plant is a Burfordensis which I bought last year. It's also a fantastic grower, and has grown 2 new bulbs this summer. It has the same growing conditions as the lawrenceana. But I can't see any spike....
I am afraid they get to easily dry because they are potted in sphagnum. What do you think?
Do any of you have photos of these plants in spike?
