How long for Blc Chia Lin 'New City' to bud?

[ardera]

I got this orchid in the beginning of June, and it had 2 very small (just beginning) sheaths. The sheaths are nice and big now. How long (on average) should it take to start some buds in there? Should he have started to bud by now (two months later)? Do I give up on the idea of getting any flowers for now? I'm trying to do what I can to make it happy. It's in an east window (in the brightest corner), I had been fertilizing every time I watered (twice per week) per the orchid nursery here, using their own fertilizer brand. I'm thinking of bumping up the watering schedule to every other day. Thoughts on this? I also got a little humidifier to try to bump up the humidity, but I'm not sure if it is working. Got it second hand, but it is one of those mistless humidifiers. I'm in CO, so it is rather dry, and I think that the moisture just dries up immediately. Any suggestions, as to anything else I can try? I really want him to be happy.
