Help with a young Ascocenda Kulwadee with few roots!

[itzi]

I've gotten this little Ascocenda Kulwadee Fragrance No. 17 from Lowes because the prospect of raising it seemed like a fun challenge. When I got home with it, I noticed most of its roots were dead, and after pruning only a few short roots remained. I grow it in a western facing window, and the temperature and humidity near it are usually around 35-40% and 75-80°. I have a small fan near it to provide airflow.

I've looked into the various ways to grow Vandaceous orchids, and I've settled on something similar to the vase method. I have my orchid in the little pot it came with, which I cut more holes into, and placed into the mouth of a mason jar with rocks and water at the bottom. When I notice it seeming dehydrated, I soak it, still in the pot, in a smaller container that I fill with water up until the base of the first leaf.

I am noticing that by the end of each day it seems pretty dehydrated, and it seems I'll have to be soaking it every day. Is this the best way for me to ensure it survives and grows new roots ?
