Help!

Hello,

My Dend is finished flowering. Can you advise as to whether the spike should be cut back to the base of the plant, or cut off at one of the nodes.

Also, in addition to the humidity trays is there another method by which I can raise the humidity for my orchids? I'm growing them indoors and now with the A/C running, I feel the humidity level is greatly reduced.

Thanks in advance for your assistance!
