Lophophora Williamsii var. Caespitosa Graft

Today I grafted a pup from my Lophophora Williamsii var. Caespitosa. This particular pup seems to be cristata or have some sort of mutation (monstrose). It was grafted on top of a Unidentified Trichocereus that I picked up from a local garden centre.
The graft went well and the Vascular Cambiums seemed to be lined up fine. I did have some trouble trying to fix an elastic band over the scion (it kept sliding around).
Only time will tell how well it will do!

I hope this to grow well, I am really interested in how the Lopho will form!
