My first two orchids (two more enroute

) were a Den. Bellatulum and a Soph. Cernua. The Den. B. is growing great!! New psuedobulbs with leaves growing out of them!
The Cernua hasn't changed in appearance one bit since I received it(approx 2 weeks). Conditions in enclosure are 78F during the day and about 65F at night. 60%-80% humidity always, allowing to dry slightly between waterings. Two 30watt, full spec CF bulbs about 8-10" from the chids
Am I expecting too much? The Cernua has a leaf that has been closed (folded in half) since I received it and has not changed at all. Any ideas? Thanks much!
