Encyclia cordigera help????

[The Orchidist]

I was at an orchid show back in the spring of this year and found this flower , it had an amazing scent of chocolate as the sun shined on it , after 2 mnths the flowers fell and the spike started to dry up . I cut the spike down almost to the base of the leaves since the stem comes from between them , I decided to seperate the plant in two.. I dont know if this was a good thing to do ????. and wondered how long it takes for pheusudo bulbs to regrow as the 2 that were there are now shrivelling up . I repotted them into 2 clear well draining pots and used spagnum moss and bark for both and have them under
T5 lights 15.5 hrs a day . Am i missing anything ?
