Draculas disappointment

I got two new dracs last spring to try out - chimaera and simia. Just to see if I can grow them. They live in the basemnet where it is cooler than the rest of the house.

Well, they didn't die and do try to grow but here is what happens with new growth:



It is Dracula chimaera.
New growth starts, grows, grows and then becomes all ruffled. Then it just breaks off the plant. This is third new growth that came out with ruffles. Why??!!
Dracula simia does almost the same, well, her leaves are narrower, but same idea. The only dracula that grows normally - lotax.

I do let moss to go bone dry between waterings, maybe that is the problem?

I am going to keep it wet at all times now and see how the newest little nubbing turns out. If it will ruffle too - no more draculas for me!
