I neither have experience with the gravel you are talking about or worm castings so I can't be of much help. However, if you can list the approximate size of the gravel, I'm sure there may be a few folks who can impart a little more knowledge on us
I don't think I would use the granular peat either unless you just happen to have a box of it laying around. The regular Canadian Sphagnum Peat Moss will work fine and is much cheaper.
