{{gwi:146248}}I think that I would wait a bit longer and get more roots. Here is one I rooted a couple of years ago and it is doing fine, and will bloom next year. Your backbulbs still have plenty of energy to supply the new growths.

My new growth is white because I kept it in a cool dark place and it started turning green as soon as it was potted.

Congratulations on getting these started. They look very good.

Thank you Richard. Infact, I asked for your advice in my other post :-)... but you didn't see it, perhaps.
So now, I will put the bulbs back into the bag and wait for some more time.

BTW, I couldn't see your photo! Something wrong with my internet line, I guess. Thanks anyway.

When you pot them be very gentle. The roots are brittle and will break easily. Do not try to bend them.

Xuan,
That is great advice from Richard. What kind of mix have you planned to use in potting up the sprouted back bulbs once they reach that stage?

I would plant them now, as I am paranoid about breaking new precious roots as they get bigger (I am clumsy). I have had good luck starting backbulbs cymbidiums in straight sphagnum moss in small clay pots

Well... :-)! To pot or not to pot!!!
Anyway, maybe I will wait another month, firstly because I don't have the time right now and secondly, I don't have the "right" mix right now.
Over here where I am, I don't have any pre-mix orchid potting medium, no fir bark, perlite or the like. People around me use what they call "tree fern", very dry and porous, mixed with decomposed goat manure + little bit of lime to pot their cymbidiums. I have been using the same thing minus lime... for my other cymbidiums. So, I think I'm going to use the same mix for these bulbs, maybe I will try to tear the tree-fern into smaller bits. I also have some sphagnum moss and some pine bark that I can use too.
What is your advice here? Many thanks.

I use treefern/sphag/perlite/pebbles mix for some of my cymbidiums...Medium size tree fern...But I am in florida- not a cymbidium heaven :)

That sounds fine, using the same as for other cymbidiums.

Many many thanks to all for your inputs. I will definitely take your advice.
