Rehabilitating bareroot Cattleyas?

[DavidCampen]

Next week I expect to be getting a shipment of a couple dozen Cattleya and Laelia species from Brazil via Miranda Orchids in Florida. By the time they get to me they will have been in transit for perhaps a week.

One question, I have not been using any rooting hormone when I repot but in those cases there are still significant roots. With bareroot orchids arriving from Brazil I expect that the roots will have been severely trimmed. Should I use a rooting hormone when I pot these and if so what types do people use?

I just noticed that I really should have put his in the potting&repotting thread. If a moderator sees this perhaps you could move this.
