Cymbidium Aloifolium - PLEASE HELP WITH DIVISION???

[TOMMYMIAMI]

So, I did order this cymbidium because I read about it in Kevin's thread and it just looks amazing, than I found it is worm grower, and than I found actually seller from Florida selling the only division on the ebay. I went for it and order one. Seller was quite nice and sent me 2 divisions. They are REALLY BIG first of all, nothing I did expect, and they are divisions, and I have no clue what to do now. Seller wrote she grows them all outside, in Florida, full sun, and using Hydro pebbles charcoal mix. I really do not know what to do with them now - I did not expect this giant division, it has some 25" plus. First of all - should I pot it already, even it has no roots (seller said these have just small root system)? If I should pot it, than please help me with the mix and also what pot to use, they are huge, clumsy and not holding, so it will need support, but I do not want to ditch them too deep, I am afraid they will rot??? For now I did just put them into the pot with little pebbles on the bottom. Many thanks for any tips, I love this one, and would love to see it bloom here at my balcony.
