Initiating Catasetum Root Growth?

[SirCatofBloominCheshireC:]

Hi, I have a Catasetum that has been resting for the past 6 months. I only gave it a little bit of water recently since it began it's resting period. I had thought it would have started growing roots by now as this is when it seems like their time of the year to grow. I live in a northern cold state in a very dry region, and have the plant sitting on a filtered, bathroom windowsill. It isn't really potted at the moment, just sitting on top of it's bark in the pot. It had 3 backbulbs and 1 new growth when I got it, but has since used all the energy from the backbulbs to plump up the new growth. It has just been sitting there on the windowsill like this for about the last 6 months. Aside from the now shrivelled backbulbs, the new bulb looks good and firm and green. But is there anything I can do to help the plant out? I had to cut off the old roots it came with because they were growing lots of mold just after I got it. I've been thinking maybe I should sphag n bag it to raise the humidity, but I don't want to risk rotting it. I've heard catasetums are quite prone to that, and this is my first one.

Thanks to anyone willing to read all that and give helpful advice
