Here is a video which follows the procedure I used quite closely......



I do want to apologize for not knowing the date I started this.....



I actually didnt expect my first graft to take.....



Other experiments are in planning.....


My guess is that I did the graft about 2 weeks ago.... maybe a day or two less than that....

Thanks for the update Burnt!

Can you post a pic of your graft?

 

[Budley Doright]

No camera....


the part I grated was a very small branch .... the leaves were removed and 2 nodes were left...


this left the chip part and about an inch of skinny stem to be grafted....as in the video....

This brutally simple method works well , bottom two nodes male rootstock , female top is a suitable stem diameter match from the same cross , does not have to be the same cross or sex.

Use pretty much anything the plant tissue will not react badly to or rot , plastic straws , sharpened matches , cocktail sticks , medical stents all work fine.

The hollow stem serves no water transport process , is eventually filled with pith and closed solid at every node , internal splint works fine.

Knitted together in a week usually , this one can go outside and F2 itself.

Its a variation on an old tomato technique when it was standard practice to graft onto desease resistant rootstock , this way requires no fiddly wire support and is much easier and repeatable , tape keeps light off and mould.

Foomar..... thats very cool....


My graft is about the same....



The leaves have opened a bit..... but growth is very ..... slow......



Im a little surprised at that....



But the graft looks great.....


Im hopeful that the leaves beginning to open is a sign its going to start growing....

Remember doing it with toms in late 50,s

Grafting Tomatoes

If you prefer the taste of heirloom tomatoes, you know there's no going back to
most of the disease-resistant hybrids. But those hybrids grow so nicely. So take
advantage of that! Use them as the rootstock.

List of Materials
Heirloom tomato plant
Disease-resistant tomato plant
Gallon pot
Potting soil
4 stakes: These will protect the tomato from the plastic bag, so they should
be about 6" taller than the grafted plant
Clear plastic bag: This will cover the grafted plant and part of the gallon
pot. It should be at least 6" taller than the plant, and wide enough to
surround the plant without bending the leaves, as well as to go over the pot.
Razor blade or grafting knife
Rubber band large enough to go around gallon pot without effort
2 rubber bands or equivalent, very soft, 6" long: These will be used to tie
the graft union together, so they must be so soft that they can hold the
pieces together without bruising the stems. Cut the rubber bands once to
unloop them.
4 wire plant ties at least 6" long.

Choosing Which Plants To Use
Select a healthy heirloom at least 6" tall. You will cut it so you have about 4"
of stem on the cutting.
Choose a disease-resistant variety that grows really well in your site. Select a
tall, robust plant. At a height of at least 6", preferably more, the rootstock
plant's stem should be the same diameter as that of your heirloom's join point.
Note: I grow only indeterminate tomatoes, and I've always used indeterminate
plants for rootstocks. I have not tried using cherry tomatoes. I'd like to hear
about results using other kinds.

Key Ideas
You want to put an heirloom cutting with about 4" of stem onto a
disease-resistant rootstock, and you want the graft union to be high enough so
that there's rootstock stem to bury afterward. You want the diameters of the two
stems to be the same at the graft union. (This is where the two pieces are
joined.)
The two grafted pieces must be gently but firmly touching at all times. The two
pieces must not move, dry out, or get cold. The pieces must start off in optimal
condition.
When you plant the grafted tomato, no part of the heirloom should touch the soil
or mulch.

How To Go About It
Soak both plants for an hour.
Repot the rootstock in the gallon pot. Do not bury any of the stem.
Note the diameter of your heirloom at its join point, where you'll cut it.
Find the matching diameter on your rootstock.
At the leaf node just above the rootstock's join point, chop off the top of
the plant.
With the razor blade or knife, cut the top of the rootstock's stem into a V
shape. Begin the downward cut from the side of the stem. Make the cuts meet
cleanly in the middle of the stem. The angle of the two cuts should be around
20 degrees.
With the razor blade or knife, cut the heirloom's stem so that it exactly
fills the space in the rootstock's stem.
Position a stake so that the two pieces are perfectly aligned. Fit the two
pieces together, and tie them to the stake.
Wrap a soft rubber band very gently around the join and tie it. Use two if
necessary.
Poke three stakes into the outer edge of the gallon pot so that they prevent
the plastic bag from bending the plant's leaves.
Water the plant.
Put the plastic bag over the stakes and plant. Fasten it onto the gallon pot
with the big rubber band, by moving the rubber band up from the bottom of the
pot.
Put the plant in indirect light, where it's at least 65 degrees, and there is
no wind. Keep it there until you see new growth from the top. Do not let the
soil dry out.
Do not allow any growth from below the graft union.

When the grafted plant is growing, gradually remove the plastic bag over
several days. Begin by unfastening the bottom of the bag and leaving a space
between it and the pot. If the top shows signs of wilting, put the bag back.
Remove the rubber band when the graft is established. The tops of the
rootstock will tend to splay apart if given the chance, so be sure there's new
tissue in the gap.
Gradually acclimate the grafted plant to full sun, over a few days.
When the graft is strong and acclimated, plant it out. Do not allow any part
of the heirloom to touch soil or mulch.

Im hopeful that the leaves beginning to open is a sign its going to start growing....

exactly, first week growing is slowly, but after they should grow faster

very nice @ fumare
Thxs

Has anyone tried multiple cleft grafting to a fully developed root stock? ie growing and flowering a plant to harvest and then cleft grafting the next round onto the existing root stock?

Save a lot of time not having to grow any roots...

[freeskierpj]

Very cool and interesting. I'm curious to see more from this thread so keep on keepin on!

 

[dtrain01]

Excellent post!

 

[Apfel]

im still in business guys,
thinks are growing up
i `ll make a final report in the end of this year.

peace

 

[Field&Stream]

This kind of stuff is pretty cool, keep us updated!

 

[GP73LPC]

how did i miss this thread... great info....

 

[Behind_The_Mask]

Very cool i used to do this with Bonsai never thought about grafting a dope plant

i love the multi mom idea i cant wait to see how these turn out

good job brothers

 

[Leathermonster]

WOW. Ive got a mature plant Im currently revegging and Im seriously considering trying this for fun. Quick question: would taking a cutting from a male plant and attaching it to a female result in pollen production on the one graft or would it force the graft to produce flowers?

 

[Leathermonster]

Good question. Id love to know the answer from an experienced gardner here!

 

[foomar]

By experiment , the male branch remains so and produces viable pollen , the female branches remain female without intersex , an impractical curiosity but fun.

Same with grafting a female top onto a male rootstock , any lower male shoots below the graft remain male and the top flowers as normal.

Have revegged half a plant with the rest in flower through a hole into the flower room , seems no transfer of hormones between seperate stems.

Now that's interesting! Something in the back of my head is screaming that there's a very practical application there.

Thank you for taking the time and resources to research!

I do not flush, I grow organic in the earth.
When Cannabis flowers all the Cannabinoids and terpenes are produced by the flowers not the roots, stems, etc.
What I mean is that while grafting may effect the growth pattern, it has no effect on THC levels, Cannabinoids produced or terpenes produced. You can graft a THC only branch to a Hemp CBD only plant and the grafted branch will still only have THC no CBD, the same with the opposite CBD branch to a THC plant, the CBD branch produces no THC. I did this and tested it with a GC, none of the Cannabinoids from the main plant had any effect on the grafts Cannabinoid profile. Understand?
-SamS

Sam i was just going to say this exact statement until i kept reading threw the pages. yup it doesn't affect anything really.. just allows for more strains on a mother.. mainly only good for people with small mother rooms.. or need plant limits to be low and want to keep a bunch of strains around.

but sam your a person i look up to .. ever since i started smoking i wanted to grow.. now that i grow it .. i want to breed and cross with it.. now that i started crossing strains. i want to learn everything there is to learn about the subject because im hoping one day .. i can have accomplished even half of what u have accomplished and i would be ecstatic .. and i appreciate the fact that u are on the forum. alot of the other guys.. dont like to get REAL Feedback.

much love and hope all your future projects are a complete success

Great info here folks. No experience yet but here's the best of my 3 years of research into grafting:

Grafting Video Bubbah http://www.youtube.com/watch?v=isbGKb7Snzk It's for the purpose of grafting a scion to a different rootstock and then getting rid of the undesireable scion and rootstock, not for a multi-strain plant. Just don't cut off the new scion and we're good to go.

Selecting the Right Graft http://www.youtube.com/watch?v=eDQJUSdyg4M This one is with apple trees but gave me an understanding about gragting and shows 2 methods that work with cannabis (cleft & whip and tongue) and the other 2 might work too.

Cleft graft_HOW TO EASILY GRAFT A MARIJUANA PLANT TUTORIAL - STEP BY STEP - GREEN PLANET NUTRIENTS http://www.youtube.com/watch?feature=endscreen&NR=1&v=_Vy_NFZwkcs Just found this one about a month ago. It's probably the easiest and most foolproof grafting method I've seen for our application.

Single cotyledon grafting http://www.youtube.com/watch?v=SxTvFcVYhBI&feature=related Food for thought.

Thanks all.
