So, I'm planning a little experiment and I would like some feedback, tips etc from the community.
I would like to keep two possibly three strains within my mother tent so I have a nice selection to choose from. I like to keep an night time and daytime smoke in my tubs as well as something exotic for little treats

I have a fairly old plant that I was going to bin and rotate but after watching crap on grafting fruit trees on YouTube it got me thinking. Could I graft 2-3 strains onto one root stock and have one mother with multiple strains growing off her? This would make me very happy if it works!
Has anyone had any experience with grafting different strains? If so, we're there any gotchas or changes in the characteristics within the cultivar? From the brief research I've done it would seem that there shouldn't be any changes but I did read that some trees are grafted onto older root stock so they fruit short and makes it super easy for people to harvest because they didn't need a cherry picker or ladder.
Here's a picture of the legs of the root stock. A little thin but I think that could work in my favor.
