S/H transition w/o new root growth - thoughts?

[orchidphile]

I had a big cattleya that dried out on my porch and had no roots. I split it in half and put one half directly into semihydro, with the reservoir filled, and one half in the sphag and bag method. The plant in semihydro took longer to root, but now both are in semihydro and doing equally well. I've also transitioned plants at the wrong time and all of them came around eventually.
