How to bloom Bulbophyllums in General

[CattleyaMan]

I really enjoy Bulbophyllums and I have many of them. But over all I feel I could use some help blooming them. I have the temperature in my greenhouse intermediate and humidity is about 75 percent using a fogger. Good light. I have six fans going 24/7 at lower speed. Most of the Bulbo's are planted in Sphagnum moss either in wooden baskets or bulbo type clay pots. I keep the moss moist but not wet. Watering once per week with MSU fert. Seaweed other weeks. Any new ideas for me to try???
Thanks,
Gregory
