I've got a small keiki more than 10 years ago. It has grown into a cane of almost one meter. I grow it in a plastic pot with a mix of sand, expanded clay and slate, bark and peat. I repot every other year.
During the growth period I water and fertilize intensely like catasetums. From November to April watering is very restricted. The plant remains in the pot.
As the growths cycle is much the same as for catasetums, they spend the winter side by side.
Does your plant have several canes?
