ive treid grafit in the past but didnt have the right tape to use to bind the cutting into the v space in the branch on the plant, i was using gardners tape or what ever its called,
but ive got some rizla that are like plastic, made from grass or something like that, so i was thinking i you cut the cutting as your suppose to so the end is a v, then at a node on one of the branches you open the branch up so the v on the cutting fits in nicely, then i was thinking using rizla would creat a more airtight seal as you could wet the rizzla and stick it on properly, that way you know their is no air gaps that could cause problems, the rizzla when wet would be easy to mold around the stem and node, then you could use 2 or 3 rizzla and that should hold it pretty much air tight while the cutting takes, you could always wrap tape around it after you use rizzla, but thats the method i would try next time as i found the tape i used just didnt create a good enough seal around the cutting, it allowed it to move about so this then stoppd the plant getting moisture to it and it just died, when i put my next veg plants into the hps room ill give it another try,
i know on an outdoor plant it would work out well, you could have a small outdoor plant with say 2 extra strains grafted to it then let it veg through the growing season, then when its going into flower it would be huge and you would end up with 3 strains from the one plant, grafting is hard to get right but get it right and it will pay off, i was going to try it as i could free up space by having 2 strains growing from one plant
it will be interesting to see how miwa gets on with the graft, ill give it a try once ive harvested the next plants ive got in flower, then the hps room can be put to a veg cycle and ill give grafting a try then and see if i can pull it off, i think this rizzla i got will work out well as when wet it will creat a good seal and hopefully the graft will take,
