Ok, short of gene splicing or any other process that requires an advanced lab. It's a pipedream to think of it ever being practical for the average home grower.

This could be great for guerilla growing if you can graft a few cuttings up high in a tree

Yeah, not compatible. If you could get a cannabis cut to graft to any other plant it would likely be hops and I think thats probably very unlikely.

Holy shit, overgrow! To bad they got shut down. Overgrow had an abundant amount of knowledge for growing.

They're back up and running.
I have grafted a sweet pepper plant to the main stem of a female cannabis plant. After day 1 the leaves bounced back. 3 weeks I will see if the graft was successful. I'm no scientist but I'm looking into smaller species and getting them to grow larger & produce more at harvest. Not too worried about the THC side, as we have great legal bud to smoke. Food costs and production is my focus. I'll add pics if it works. Thanks

you can make the physical graft, and the weed scion you graft to your stock plant may live and prosper, but i doubt it will ever actually flower, and it won't ever produce any kind of "hybrid" offspring. genetics are genetics, period. if you picked a plant with similar nutritional requirements to weed, you would have a better chance, plants are like animals in that they all require different nutrients in different ratios to stay healthy. if your stock plant doesn't have similar nutritional requirements as weed, the scion will probably not do well and die soon.
as to flowering, that requires hormones that the scion probably won't be able to produce in sufficient quantities to induce flowering, and your stock plant won't produce the same hormones at all
Looking into the hackberry plants in the hemp family, and other edible fruits in the hemp family now. I’m still going for it. Rooting hormones were added when I made the graft so I’ll keep em watered & covered until it heals up. If it dies… oh well. If it lives… we’ll see. Most likely just weak ass pepper plants on weed rootstock… My two Ca Wonder plants are thriving after the topping. I am re-vegging & re-rooting the tops in my tomatoes indoors. My bud is doing just fine so I like to experiment #bewell Fam here’s pic 24-48 hrs after graft was done and you can see the leaves are holding their own. Second one curled up like the first today. So I’ll see if it recovers by lights on tomorrow. Other pics are TTR taste the rainbow finishing in a couple weeks. HSH Farms IG

i'm not sure that will work at all, you might get lucky.
this is a pretty good page on types of grafts and how to make them
https://extension.msstate.edu/publications/basic-grafting-techniques-0
you usually have a stock plant (plant you're grafting to) that is healthy, and can support the scion (the stem you're grafting onto the stock plant)
what you've done is try to attach a growing limb to a rooted stem that may or may not have the energy to make it.
you'd have a lot better luck trying on a non flowering mother sized plant, that has plenty of energy to not only feed itself, but your scion, too.
you have the best luck if you can match up the diameters very closely, you're trying to guarantee as much cambium to cambium contact as you can, that's where they'll start to grow together. the cambium layer from both HAVE to line up on at least one side, both is better
Shoooooo!

Right. So the research done on peppers in particular shows possible mutations and variations of yield. But this type of graft was made with paprika. they did various tests with inter genetic testing and grafting peppers to completely different root systems. The only reason I chose this cannabis is for stem diameter, root growth, and the ability to line up the two plants cells….. Luck is not all I will need but anything helps. It’s crazy to think that most of what we know or think now was thought to be impossible a 100 years ago. Looks like the use of algae may be a possibility for a new root structures that will be able to support multiple genes in the same system… Super interesting stuff.
Grafting can transfer genes between two plants, creating new genes.

And it have been done with many plants already for example fruit plants and of course Cannabis as well.
For example hops with high amounts of THC and CBD exists out there. It's called "Legitimo" and are made by "Dr Kaly" from Kaly Seeds.
His methods are not "high tech" and they can be done by home growers, as far as I know he is only grafting and have been doing it for over 20 years.
I recommend checking out Kalys garden, he cultivates Cannabis mutants and have many strange strains that barley even look like cannabis any more.
Horizontal genome transfer as an asexual path to the formation of new species - Nature
The formation of a new species can occur by an asexual mechanism by transfer of entire nuclear genomes between plant cells as shown by the creation of a new allopolyploid plant from parental herbaceous and woody plant species, this mechanism is a potential new tool for crop improvement.

while that may be a possibility, i can tell you it just doesn't happen in fruit trees. not sure if it can happen in weed or not.Grafting can transfer genes between two plants, creating new genes.

while i was growing up, i helped my grandpa take and graft lots of cuttings, he liked to experiment...if you graft an apple branch onto a peach tree, it will grow apples. the first year they will taste like apples, the second year it will have a slight peach taste, and that's the biggest change i ever saw...they always looked and tasted the same, besides a vague hint of the host tree, if it wasn't the same species, and the seeds always grew more of the original fruit, with no taste of the host at all

You can't graft a cannabis plant on anything but hops, the fruit cocktail trees are closely related, plums cherry apricot peaches etc. Those pics of the fluorescent trees are fakes.

I believe you can graft anything together that starts with the same amount of cotyledons. Some plants start with 1 and some with 2. Anything that starts with 2 cotlyedons can be grafted together and likewise with 1. I’m in Hawaii and have wanted to graph cannabis to the lilikoi. Maybe it would bring in some flavor or something to it, I have seen other grafting projects and typically the graft does its thing with no real effect from the plant its grafted to, but you never know. Great thread!

for most plants, you need to line up as much of the cambium layer of the bark on the graft and the host as possible. If the layers of bark on either are significantly thicker or thinner, it makes it exponentially harder to achieve success.
this is an interesting article, but the image at the bottom of it shows the proper technique for what you're talking about...I have no idea if it will work, and doubt it, but the things i don't know will fill volumes...try it and let us know.

I've been dreaming of cross breeding pot and hops for the sake of brewing a naturally THC infused since I was about 14. Is there any research available on such a thing? Which sex of wich plant would be best used as the graft and parent. I'm assuming you would put a male graft on a female host, but I'm years away from doing any form of breeding

From Missouri botanical garden, even some of the same species can't be grafted, this is a very well known principle... Hops are probably the only one
Not all plants can be grafted. Generally, only plants closely related botanically form a good graft union. Grafting is not a means of developing new varieties. The stock and scion must be compatible. Incompatible grafts may not form a union, or the union may be weak. A poor union results in plants that either grow poorly, break off or eventually die.

Been a while havent been on rollitup in decades but.
Why does it seem some of you in here dont know that grafting does have an direct effect on the traits of the plant.
Phenotypic variation in grafted plants
Grafting commonly influences the phenotype of the grafted plants, including changes in fruit quality, resistance to pests and pathogens, tolerance to adversity and stress, and other physiological disorders. The vegetative fruit quality of scions is commonly altered by the rootstocks after grafting. It is described as a case in which two pepper scion cultivars acquired changes in fruit shape, color and pungency after grafting. The results also illustrated that several rootstock features were present in the progeny of the scion after self-pollination. Similarly, a graft of three watermelon cultivars and three hybrid squashes showed differences in shape, weight, yield, quality, rind thickness and pH among stocks. Fruit trees, such as sweet cherry, apple and citrus, have also been shown to be influenced by grafting.
Grafting is widely used to improve resistance to pests and diseases. For instance, grafting can alleviate the development of post-harvest diseases in Hass avocado fruit. Anthracnose, caused by the fungus Colletotrichum gloeosporioides, is the most severe post-harvest disease of avocado fruits. The rootstocks can significantly affect the post-harvest anthracnose resistance of scions, which is probably related to an increase in antifungal diene and improvement in mineral nutrients in the scions. Research on the resistance of pepper plants to both phytophthora blight and bacterial wilt also confirmed the effect of grafting. Five commercial stocks and nine breeding lines were used as rootstocks for the scion ‘Nokkwang’, three of which were selected for their greater resistance to phytophthora blight and bacterial wilt without reduction in productivity or fruit quality. Furthermore, a study using tomatoes revealed that cultivars grafted onto nematode-resistant rootstocks gained higher yields than did nongrafted ones. Similar results have been found in eggplants, cucumbers and peppers.
Grafting can also affect tolerance to abiotic stress. Experiments in cherry tomato found that grafting on drought-tolerant rootstocks resulted in higher fruit production. Several studies have shown that salt stress in cucumber can be alleviated by grafting cucumber onto Cucurbita rootstocks. Alleviation of salt stress may be due to delaying photo-inhibition, which is caused by changes in nitrogen metabolism during salt penetration. Other examples, such as the tolerance of citrus to boron stress and the resistance of tomato to thermal stress, provide more options for exploring the mechanisms of this phenomenon.
In addition to the cases mentioned above, related publications have indicated that physiological and morphological features can be altered by stock–scion interactions. The ability of rootstocks from certain fruit trees to dwarf their scions, which has been acknowledged for decades, is used in agriculture. A series of rootstocks used for dwarfing has been developed in apples, and genetic marker analysis linked to the dwarfing traits has been performed. In micrografting experiments in Arabidopsis, found that the wild-type (WT) stocks can effectively inhibit rosette branching of the increased branching mutants max1 (more axillary growth) and max3. Notably, when two shoots from the max1 and WT seedlings were simultaneously grafted onto a max1 rootstock, the mutant shoot showed increasing branching while the WT shoot did not. When the max1 rootstock was replaced with a WT rootstock, neither of the shoots branched profusely. The results indicated that branch signaling can spread from root to shoot but not from shoot to shoot.
The majority of current research has been dedicated to using rootstocks to influence shoot phenotypes, but the root changes induced by scions have been seldom discussed, probably due to the important role that scions play in agricultural and horticultural practices and also the relative difficulty in observing root phenotype changes given that they are below ground. However, the effects of the scion on stock growth and carbohydrate storage seem to be indisputable, and root–shoot interactions remain to be explored further.
