I've heard of folks trying to graft mmj cuttings to a mature hops host-plant, before. Something about hops being a close genetic relative of mmj, but yielded negative results.
Why would you even want to graft cannabis together like that? Growing/keeping moms for grafting would be easier, wouldn't it? (Sure would be a bitch to work around too, lol)
Rusty Trichome Reviewed by Rusty Trichome on . marijuana grafting ok ive seen it done it and smoked it! stalks of cloned buds not cloned leaves will cause the stem to get larger each time cloned and if cloned enough the stem will be the size of your arm. Rating: 5
