Wow yours is huge!! Is it a fast grower? I left mine in the pot it came in, and put it in a bigger pot of soil, and then covered it with the gravel. I hate transplanting them...hehehe. Plus I've always been told, do not move a cactus to too much larger of a pot, at a time, so this resolves that problem When you look at it, you can't tell it's planted in a smaller pot inside.
