Grafting your clones!!

Was wondering if there was any grower's out there experimenting with grafting. im thinking of putting my mother roots to use instead of ditching after cutting for clones,
like mybe make a lolly-pop tree with a few different strain's on the main stalk.. just looking for any outher's that have tried...Or has successful grafting project's mybe with a squash vine tomato any outher's.................
