Stanhopea cutting with no roots

[TheDirties]

I received these cuttings today, sadly only one had a root. Will these bulbs be able to regrow roots?
I am planning on leaving them in a makeshift greenhouse, maybe sitting on some perlite.
I also have a rooting agent with indoleacetic acid and naphthalene acid.
Im in the East-coast Australia, so nights are 10 degrees and days 20 degrees.

Is there any hope?

The two on the right seem to be broke off without any base tissue. I doubt they will produce any roots. Might be worth trying rooting hormone if the consensus is that they are a lost cause. The one on the left still has some of the base attached and I've gotten S. wardii pieces like that to recover though I've lost some like that too.

Cheers for the reply.
What was your method of recovery with so little base left?
I think this might be a s. wardii as well from what I remember.

For the most part with something like that I just tuck it into a pot that already has an orchid in it and leave it there till it either starts showing some growth or looks like I can toss it. It get's watered and cared for along with the other orchid.

You will find some useful info in this thread.
One of the pbulbs I was offered is a Stan wardii which is today fully grown and blooming. In fact, all of them are now fully grown, except for the in the worst condition which was lost.
