very interesting idea, i have no clue as to what would happen but id like to find out. you might run into problems with there not being enough plant above ground. the size of the plant is in step with the size of the rootmass, too much of either one and the plant dies.

(roundup works by making the roots grow super fast and the rest of the plant can't keep up so it dies)

if you can get past that issue, i'd think you could get some faster growth...anyone else?
FlyGuyOU Reviewed by FlyGuyOU on . Root grafting When plants grow, I assume a lot of their energy goes to making roots. What would happen if after harvesting a plant, and leaving the roots in the soil, you grafted a clone on top of the already formed roots? Would it work? Would there be accelerated growth? Or would it be forever crippled? Rating: 5
