Actually..no one has attempted it...and no one knows exactly why some does not graft. This is what is called emerging science.
It takes trial and errors to know for a fact it does not work. Proper science is not saying something can not work unless the trial and errors has been performed.
Like I stated before...there has been cases of plants from different families actually grafting and staying alive for 5 months...5 months is enough time for a cannabis plant to be harvested.
and not to be rude..but where exactly is your grafting trial and errors..or anything else science related? Just saying.
Herbaceous plants of different families have most defiently been grafted and lived for awhile..tomato and cannabis are both herbaceous. So you can not say for a fact it would not work. Feel free to post photos or anything that has showed any attempts to graft cannabis to a tomato.
Cellular recognigtion, wounding response, growth regulators, and incompatable toxins are what determines if 2 plants will graft.
Successful grafts have been made with the following plants of different families:
Tomato and Cabbage, Tomato and Chrysanthemum, Tomato and Cineraria, Tomato and Coleus, Tomato and Zinnia.
Other examples include:
Kidney bean and Cocklebur, Kidney bean and Castor-oil bean, Sunflowe rand Melon, Jerusalem artichoke and Black nightshade, Coleus acaranthus, Aster and Phlox, Maple and Lilac.
The Tomato and cabbage and the artichoke and nightshade gave good unions on account of their "herbaceous" nature and rapid growth, while astor and phlox, somewhat advanced in growth, and a year old maple and lilac united with difficulty except on very young shoots. The success of these experiments concludes that the "old" idea that only plants belonging to the same family can be grafted on each other does "NOT" apply to "grafting by approach".
Does this mean an approach graft?
An approach graft is something that happens even in the wild and requires close proximity of the plants. The reason it works well in many cases is because both plants being used are still being supported by their own root stock. What happens when the scion is separated from its own root stock is what matters. I’d be curious to hear the long term survival rate of plants used from different families.
As I said before chances are slim when you go outside families…I didn’t say it was impossible. I guess the important question is is it a viable option on a practical or commercial scale?
My approach would be to find the cultivars that produce the strongest root stock and go from there. Commercially, root stocks are used for hardiness, disease resistance, and/or dwarfing.
Speaking of autos, I remember reading some threads about using approach graphs with autos and standards but leaving everything intact (both scions and rootstocks). Something about the hormones going both ways in regards to flowering. Florigen I believe. The theory was to graft an auto or fast flowering to a long flowering tropical.
There is ALOT of advantages to grafting that can not be gotten in other means...alot of these advantages have already been covered.
Planting a bunch of seeds will not give you the advantages of grafting such as size boost, controlling height, mold and disease resistance, among the many other advantages.
"you can grow any plant to have a big root mass and it will produce more." Sure if you keep increasing the container size...100 gallon container will of course grow a more massive plant..however big bud or money maker in a 100 gallon container will produce a even bigger plant. However bigger container does not effect genetics. The root mass however is genetic. Bigger the root mass then the bigger the plant...nearly everything starts in the root mass. Big bud and money maker naturally creates big plants...so is logical to use them as rootstock to get size boost.
Adding chemicals to get a bigger plant becomes a less healthy product...however with grafting you do not need the extra chemicals however voodoo juice helps in grafting for size. This give us another major advantage...size boost without chemicals.
Your comments are wildly overstated.....
The only reason we might like to do grafting here is for plant count....
Thats pretty much the beginning and end of it......
I've read the whole thread and have experience grafting cacti.
I haven't seen any proof of what this person is claiming (pics) and they seem to be just extrapolating from other plants and assuming it will be the same with cannabis (larger buds of say GSC on Big Bud root-stock? Pics?)...
