Also, you might consider a bottom heat propagation set-up (after researching whether grapes respond well, I suppose). If you've got a seed warming mat, you could put a bucket of water on top of it and stick your cuttings in the water (or into floating cups of growing medium within the bucket). The difference in temperature should help to speed up root development.
