    Does it have a growth ? Leaves ? Roots ? Or just a lump like a potato ?

    No growth at the mo. I have just put it in a pot of orchid compost pointed end uppermost. I don't know about watering it and what to look for signs of growth.

    I'd say keep it lightly damp so you don't get rot, but enough dampness to wake up any eyes that may be alive and ready to grow. I don't know if I'd bury it in the media, or maybe just part way so there is some light exposure too.

    Hello
    I had some luck growing 2 cymbs, 1 from a back bulb, t and 1 from normal pseudobulbs.
    So what I did with the back bulb was clean any rotted plant material from it, carefully so not to hurt any existing eye, an put it lightly on a top of a fine coconut fiber/perlite 50/50 mix. I fixed the bulb in place by tying it to a bamboo stick. I kept the medium moist, in the glass house, around 20 degrees Celsius, indirect light ant 75-80% humidity. The back bulb I put on top of the media had an eye, and I had a new growth with roots in about 3 month. I had another back bulb from the same rotted cymb, which I placed a few mm in the media, and that rotted away. After the first roots appear I fed the new growth with some hydroponic growing solution for orchids plus some growth hormone for better root growth. I kept the media moist but not wet.
    Here are some photos of my saved cymb, the new plant has is about 18 month old.Name:  WP_20160105_12_47_37_Pro.jpg

    In my second attempt to save a rotting cymb I kept 3 pseudobulbs attached to each other, cleaned it of rotted plant material and repeated the procedure from above.
    In about 3 weeks first roots started growing.
    That was about 2 weeks ago, I will see the plant again tomorrow, so I can get an update.
    Here are the pics:
