back bulbs to grow. Question

[orchidsarefun]

I have successfully propagated single bulbs of zygopetalum, catasetum and cattleya. I wouldn't take a bulb off any plant that would leave less than 3 plump bulbs on the mother.
I placed them upright in single pots, on a thin layer of sphagnum moss and kept it moist. It takes a while but eventually new growth will start..........if you are lucky. After the new roots are at least an inch in length I potted up in a mix of bark and sphag - about 60/40. As the bulb grows and develops foliage you can think about repotting into its normal mix.
As for resources - at the time I couldn't find anything worthwhile either.
