I recently heard you could graft hops vine to cannabis stock and the hops would contain T.H.C. I brew beer and am planning on getting some root cuttings of hops this spring anyway and was considering trying this has anyone tried this or known anyone who has had any sucess with it?

Well after thirty seconds in google i found this:

1.) Construct or procure a large flat bed no less than six inches deep and fill nearly to the top with good soil which has an acidity between pH 5 and 7. Work in some manure, but not too much, and do not use any high nitrogen chemical fertilizers as this will lessen survival chances of the grafts.
Use flower pots and follow the same soil and depth requirements described above
Use the site on which you plan to grow your pot-hop vines
If you wish to attempt this project in a hydroponic growing table use a moderate nitrogen formula. HYPONEX is fine. If you mix your own nutrient use a preparation similar to Formula B described in the article on hydrophonics in this manual. Do not use formula A or C at this time or your grafts may perish.

2.) Having chosen one of these growing places, plant seeds from the very best marijuana you can get your hands on. Highest quality Michoacan, Panama Red, Vietnam or Acapulco Gold are preferred. Because of environmental influences any of these are likely to be natural triploid, or tetraploid varieties, that is, they may have one or two extra sets of chromosomes. Such mutants not only produce more resin, but are also larger, healthier and more likely to survive grafting.

3). As the plants grow weed out the inferior ones which tend to crowd the others. By 45 days from the time of planting they should be spaced about the ten inches apart, or one to a flower pot.

4). At the same time that you start the marijuana also plant hop seeds. Choose one of the several polyploid varieties available at most seed houses. Follow the same soil and planting instructions as for marijuana.

5). When the plants are 45 days old lay some kind of marker (a toothpick or matchstick will do) at the base of the marijuana plant parellel to the cotyledons (the unserrated first leaves that came out of the seed). With a single-edge razor blade sever these plants below the cotyledons, about an inch and a half above the ground (Fig. 1). Discard or smoke the upper portions of the plants.

6). Sever all of the hop plants at approximately the same point. Make sure that at least an inch of stem extends below the cotyledons to the point of severance. Uproot and discard the lower portion of these plants.

7). Split each marijuana stem about 1/2 inch downward from the point of severance. Make this split perpendicular to the marker which represents the directions in which the cotyledons extended from the stem (Fig 2).

8). Cut a slant about 1/2 long at the base of each hop stem. Make the cut perpendicular to the cotyledons of the hop scion (Fig 3).

9). Insert the hop scion into the split in the marijuana stock so that the slanted wedgewound of the hop makes direct contact with one side of the split-wound in the marijuana. Allow about 1/16 inch of the hop's slanted wound to show above the severance point of the marijuana stock.

10). Bind the graft with flat grafting raffia about midway between the top and bottom of the split.

11). Smear graft sealer around the wound. Graft sealer and binding raffia are available from most nurseries.

12). Allow the wound dressing to remain on the plants for about ten days. During this time be sure the plants receive adequate water and are not exposed to the hot sun for long periods. TRANSPLANTONE can be added to the first water to lessen the shock of the graft.

13). After ten days remove the dressing. The surgery should now be satisfactorily healed.

14). After an additional ten days the "hop" vine may be transplanted to its final growing site. The vines should be planted at least four feet apart and given a fence or preferably an arbor on which to climb. The leaves can be harvested, dried, and smoked in the same manner as marijuana.

It is not the author's place to advise whether or not you would be breaking the law by owning cannabinated hop vines. No such case has ever been tested in the courts. It is inlikely that narcotics agents woukld ever discover your secret and if they did it is very possible that you would eventually win your case. But this could be costly and time consuming. The hassle of standing trial can in many ways be worse than the penalty. Also bear in mind that it is illegal in the United States to grow the marijuana seedlings required in making this graft. The hops fruit is used in beermaking as a flavoring. If any readers are interested in home brewing they might try the fruit of "potted" hops for a unique experience in beer drinking. Those who do are warned that beer also contains the toxin alcohol.

and soon after found this:

One of the most persistent myths in marijuana lore concerns grafting Cannabis to its closest relative. Humulus, the hops plant of beer-making fame. The myth is that a hops scion (shoot or top portion of the stem) grafted to a marijuana stock (lower stem and root) will contain the active ingredients of marijuana. The beauty of such a graft is that it would be difficult to identify as marijuana and, possible, the plant would not be covered under marijuana statutes. Unfortunately, the myth is false. It is possible to successfully graft Cannabis with Humulus, but the hops portion will not contain any cannabinoids.

In 1975, the research team of Crombie and Crombie grafted hops scions on Cannabis stocks from both hemp and marijuana (Thailand) plants 205. Cannabis scions were also grafted to hops stocks. In both cases, the Cannabis portion of the graft continued to produce its characteristic amounts of cannabinoids when compared to ungrafted controls, but the hops portions of the grafts contained no cannabinoids. This experiment was well-designed and carried out. Sophisticated methods were used for detecting THC, THCV, CBD, CBC, CBN, and CBG. Yet none of these were detected in the hops portions.

The grafting myth grew out of work by H.E. Warmke, which was carried out for the government during the early 1940's in an attempt to develop hemp strains that would not contain the "undesirable" drug 58. The testing procedure for the active ingredients was crude. Small animals, such as the water flea Daphnia, were immersed in water with various concentration of acetone extracts from hemp. The strength of the drug was estimated by the number of animals killed in a given period of time. As stated by Warmke, "The Daphnia assay is not specific for the marijuana drug ... once measures any and all toxic substances in hemp (or hop) leaves that are extracted with acetone, whether or not these have specific marijuana activity." Clearly it was other compounds, not cannabinoids, that were detected in these grafting experiments.

Unfortunately, this myth has caused some growers to waste a lot of time and effort in raising a worthless stash of hops leaves. It has also leg growers to some false conclusions about the plant. For instance, if the hops scion contains cannabinoids, the reasonable assumption is that the cannabinoids are being produced in the Cannabis part and translocated to the hops scion, or that the Cannabis root or stem is responsible for producing the cannabinoids precursors.

From this assumption, growers also get the idea that the resin is flowing in the plant. The myth has bolstered the ideas that cutting, splitting, or bending the stem will send the resin up the plant or prevent the resin from going down the plant. As explained in our discussion of resin glands in section 2, these ideas are erroneous. Only a small percentage of the cannabinoids are present in the internal tissues (laticiferous cells) of the plant. Almost all the cannabinoids are contained and manufactured in the resin glands, which cover the outer surfaces of the above-ground plant parts. Cannabinoids remain in the resin glands and are not translocated to other plant parts.

We have heard several claims that leaves from hops grafted on marijuana were psychoactive. Only one such case claimed to be first hand, and we never did see or smoke the material. We doubt these claims. Hops plants do have resin glands similar to those on marijuana, and many of the substances that make up the resin are common to both plants. But of several species and many varieties of hops tested with modern techniques for detecting cannabinoids, no cannabinoids have ever been detected 212.

The commercially valuable component of hops is lupulin, a mildly psychoactive substance used to make beer. To our knowledge, no other known psychoactive substances has been isolated from hops. But since these grafting claims persist, perhaps pot-heads should take a closer look at the hops plant.

Most growers who have tried grafting Cannabis and Humulus are unsuccessful. Compared to many plants, Cannabis does not take grafts easily. Most of the standard grafting techniques you've probably seen for grafting Cannabis simply don't work. For example, at the University of Mississippi, researchers failed to get one successful graft from the sixty that were attempted between Cannabis and Humulus. A method that works about 40 percent of the time is as follows. (Adapted from 205)

Start the hops plants one to two weeks before the marijuana plants. Plant the seeds within six inches of each other or start them in separate six-inch pots. The plants are ready to graft when the seedling are strong (about five and four weeks respectively) but their stem has not lost their soft texture. Make a diagonal incision about halfway through each stem at approximate the same levels (hops is a vine). Insert the cut portions into each other. Seal the graft with cellulose tape, wound string, or other standard grafting materials. In about two weeks, the graft will have taken. Then cut away the unwanted Cannabis top and the hops bottom to complete the graft. Good luck, but don't expect to get high from the hops leaves. {Smoking any plant's leaves will give a short, slight buzz.}

you've been misinformed.
althogh hops and drug-cannabis are both members of the cannabicae (sp?) family, a succesful graft of hops to a cannabis rootstock would NOT cause the trichomes of the hops to full with the active alkaloids THC, CBD, et al...contrary to popular belief.

this kind of ties into the other myth that hanging a plant to dry upside down with entire rootball still attached, causes THC to 'flow' from the roots into the buds...OLD WIVES TALES, BOTH
have heard it to be a very popular belief still amonst folks in the PNW

Ginger Snap Canna Mead

Ginger Snap Canna Mead
Mead is a wine that is made from honey, also historically the Vikings drank this beverage for calibrations and before they went out into battle.
Mead can either be dry or sweet, still or sparkling.
The flavors in mead tend to be delicate, and is one of the wines I tend to go crazy with
Mead is one thing that should never be hurried, but rather given time to mature and reach it's full potential.
The recipe below says to let it ferment for 2-3 months in primary fermentation and 3-4 months in secondary fermentation.
I would also suggest that once it has been bottled, to let it age in the bottle an additional 6 months... Believe me it is worth it.
Ginger Snap Canna Mead
This should come out in the neighborhood of 15% alcohol by volume.
Ingredients for 5 gallons (19 liters)
18 lbs light clover honey
1 cup lemon juice
4 oz fresh ginger slices (each about the size of a quarter)
zest of 2 lemons
4 - 8 ounces of popcorn buds and trim (water cured, so as not to have a green taste.)
White Labs Sweet Mead Yeast WLP720 or Wyeast Dry Mead 3632 (depending on preference)
Bring ginger, juice and zest and 2 gallons water to a full boil. turn off the heat and pour into a fermenter (bucket with lid and airlock, glass will break if hot water is poured directly into it).
Add honey and stir well, then add cold water to 5 gallons.
Add yeast when temperature is 70º - 80º.
Allow to remain in primary fermenter for 2-3 MONTHS before transferring liquids only to a secondary fermenter at which time you place the buds and trim along with it in a silk screen bag.
After 3-4 months in the secondary fermenter it will be time to bottle.It is best after it has been in the bottle for a few months. The longer the better.

Red-Eye Barley Wine

Red Eye Barleywine
Classification: barleywine, extract

12 Lbs 12 ounces, lite Liquid malt extract
3 pounds, crystal malt
1-1/2 pounds, wheat malt
1 teaspoon, gypsum
1 teaspoon, Irish moss
2 ounces Hallertauer Hops (boiling)
1 ounce Hallertauer Hops (finish)
2 packages of Champagne yeast
¼ pound - 1 pound of trim and bottom buds (little popcorn buds work well for this).

Put your crystal malt and wheat malt into a grain bag and put it in to a pot with 2 gallons of cold water and bring it to boil. Once boiling commences take out the bag of grain, and add the malt extract, then add 2 ounces of Hallertauer hops and boil for 60 minutes, add the gypsum during the last 10 minutes of the boil and the Irish moss during the last 5 minutes of the boil at that time add the Last ounce of the hallertauer hops and cool as quick as possible and add to 3 gallons of cold water to make 5 ½ gallons of wort.

Pitch the champagne yeast and let ferment for 10 days to 2 weeks at 70 degrees F.
Once the bubbling stops siphon it off into a secondary fermenter and add your Cannabis (put it in a nylon dry hopping sack) and let ferment until clear.
Siphon beer off into a sanitized 5 gallon bucket
Add ¾ cup of corn sugar to 1 cup of hot water and bring to boil, add it to your beer then siphon into bottles and cap and let set for 2 weeks. Beer should be carbonated in two weeks. Flavor gets better with age.

Brewer’s note:
Used 1 ½ ounces of Sweettooth x Peak Flo trim and 3 ounces of White Widow trim in Secondary fermentation.
Beer was in primary fermentation for 10 days, then siphoned off into glass carboy for 2 weeks beer was clear and had a nice copper color and was more malty in flavor Hops were not pronounced, but were there in the background like an English version of barley wine. (flavor reminded me of “Old Nick Barley Wine” from England)
The cannabis in this beer creeps up on you over about 40 minutes and then it hits you full force. Nice buzz to it.
Alcohol percentage is around 10% by volume.
Made 60 12-ounce bottles.

My conclusion, It is possible to put Cannabis in beer the THC is Alcohol soluble, to do this, You need a high alcohol beer so that you have more efficient break down of the THC.
Other Side note.... Upon reflection, The beer did have a bit of a green flavor to it.
To remedy this I would suggest that before using the Cannabis in beer, it should be water cured...
To do this and not lose any of the trichomes place the cannabis in a tight silk screen bag.
That way you can take the cannabis strait from the water cure right into secondary fermentation.
Once in secondary, the trichomes will melt and become part of the beer because THC is Alcohol soluble.

Original Hempen Ale

Original Hempen Ale
(5 gallons/19 L, all-grain with hemp seeds)
OG = 1.054 FG = 1.014 IBU = 36 SRM = over 30 ABV = 5.2%
Steve Nordahl, former head brewer at Frederick Brewing Company and the originator of (commercial) Hempen Ale told the story of how his hemp beer came to be in a 1999 story in BrewYour Own Magazine. Hempen Ale was originally meant to be a dark beer, with the flavor of roasted hemp seeds playing a large role in the flavor profile of the beer. However, roasting hemp seeds wasn’t viable on a commercial scale. (Coffee roasters had the wrong equipment and malting companies feared cross-contamination.) So, the commercial beer was pale in color. Here, however, is the original recipe for Hempen Ale. [Note: In the US, it is legal to possess (and brew with) sterilized hemp seeds. (An internet search will reveal multiple sources for the seeds.) These seeds contain only a trace of THC (the active ingredient in marijuana) and have no psychoactive effects. However, it is possible that consuming hemp beer may cause you to test positive on some modern drug tests. Use your best judgement of your situation when brewing this beer.]
10 lbs. (4.5 kg) 2-row pale malt
1.0 lb. (0.45 kg) Munich malt
1.0 oz. (28 g) black patent malt
1.5 lbs. (0.68 kg) mild hemp seed (roasted)
4.5 AAU Cascade hops (90 mins)
(0.75 oz./21 g of 6% alpha acids)
4.5 AAU Cascade hops (45 mins)
(0.75 oz./21 g of 6% alpha acids)
3 AAU Cascade hops (10 mins)
(0.5 oz./14 g of 6% alpha acids)
4.5 AAU Cascade hops (0 mins)
(0.75 oz./21 g of 6% alpha acids)
1 tsp. Irish moss
Wyeast 1056 (American Ale) or White Labs WLP001 (California Ale) yeast
0.66 cups corn sugar (for priming)
Step by Step
Place hemp seeds on a cookie sheet and roast in a 450 °F (232 °C) oven for 30 minutes. Mash grains and hemp seeds with 3.5 gallons (13 L) of water; hold mash at 156 °F (69 °C) for 60 minutes. Sparge with 170 °F (77 °C) water to collect 5.75 gallons (22 L) of wort. Boil for 90 minutes, adding hops at times indicated. Add Irish moss with 15 minutes left. Cool wort, transfer to fermenter, aerate and pitch yeast. Ferment at 68 °F (20 °C) for 10 days. Bottle or keg.
Extract with grains option:
Replace 2-row and Munich malt with 2.25 lbs. (1.0 kg) Muntons Light dried malt extract, 4.0 lbs. (1.8 kg) Alexanders Pale liquid malt extract, 0.5 lbs. (0.23 kg) 2-row pale malt and 1.0 lb. (0.45 kg) Munich malt. Place hemp seeds on a cookie sheet and roast in a 450 °F (232 °C) oven for 30 minutes. Heat 1 1/8 gallons (4.3 L) of water to 167 °F (75 °C). Place crushed grains and hemp seeds in a steeping bag and submerge bag in this water. Steep for 45 minutes, holding temperature around 156 °F (69 °C). Remove bag and let drip dry. Combine “grain tea,” dried malt extract and water in brewpot to make 2.5 gallons (9.5 L) of wort. Boil wort for 90 minutes, adding hops at times indicated. Add Irish moss and liquid malt extract with 15 minutes left. Cool wort, transfer to fermenter. Top up with water to 5 gallons (19 L). Aerate wort and pitch yeast. Ferment at 68 °F (20 °C).

News Release


AUBURN, Ala.__--Taking aim at research has acquired a new meaning for Auburn University researchers who are using a special gun to explore new possibilities in genetic engineering.

The gun, known as a Gene Gun, uses .22 calibre bullets to incorporate genetic material into cell structures. The scope of its applications is broad, according to Henry Daniell, associate professor of molecular genetics in Auburn's Department of Botany and Microbiology.

Daniell is using this device to conduct Alabama Agricultural Experiment Station (AAES) studies aimed at enhancing the genetic characteristics of various crops.

Genetic engineering involves introducing foreign genes into plants or animals to impart economically important traits or to better understand the basic mechanisms of growth and development.

Through a U.S. Department of Agriculture-National Research Initiative Competitive Grant, Daniell has acquired a Gene Gun that he and other Auburn researchers are using to conduct a wide range of studies. AAES research areas include making crops more resistant to insects, herbicides, disease and salt or drought. The Gene Gun will be used on numerous crops, including peanuts, sweet potatoes, cowpeas, tobacco and mushrooms.

One area of interest to Daniell is the use of the Gene Gun in tobacco. He explained that plant material is now being used to make a biodegradable plastic, and he is working to enhance the production of protein-based polymers in tobacco plants for use in plastic production, replacing petroleum as the current source of plastic.

"In addition to applications in agricultural biotechnology, the Gene Gun is used in biomedical research," added Daniell.

He noted a hand-held version of the Gene Gun has been successfully used to correct genetic deficiencies in the livers of rats, which opens the door for human gene therapy. For example, physicians may be able to fire genes into an ailing organ that will overcome DNA mutations in the body. This type of therapy may prove useful in treating such health problems as ischemic heart disease, late onset diabetes, Parkinson's disease, Alzheimer's disease and aging, all of which are caused by alterations of the mitochondria DNA.

Daniell first encountered the Gene Gun while he was on the faculty at Harvard University and collaborating with researchers at Cornell University in New York. Researchers at Cornell invented it as a way to incorporate dye into pollen grains for genetic studies.

"It occurred to them that they might be able to use a gun to do something good for a change," laughed Daniell. "I used to tell them that one has to live in New York to think of this."

The device uses a bullet to propel genes (DNA) into the cell structure, though the bullet is simply the power behind the process. Tungsten or gold particles coated with foreign genes are put on the cylinder that is held in place by the pin loader. The cylinder is inserted into the barrel of the Gene Gun using the pin loader, and a .22 caliber bullet is then placed inside the barrel. When the bullet is fired, particles are accelerated into a chamber containing cells or tissues into which scientists want to incorporate foreign DNA. A stopping plate prevents the cylinder from striking the sample, but the tungsten particles and DNA forcefully enter into the cells.

"Until now, foreign genes have been introduced into cells in the nucleus. However, in crop plants many economically important traits are present inside subcellular compartments, such as chloroplasts and mitochondria," explained Daniell. For example, the gene for the protein conferring resistance to certain herbicides is encoded by genetic structures in the chloroplast, the area of a plant cell where photosynthesis occurs.

Another advantage of engineering foreign genes in this manner is that researchers can make genetic changes without using pollen. Daniell explained that when genes are transferred from one plant to another via pollen, genes from crop plants can be conferred to other plants, which can result in more persistent weeds. Introduction of foreign DNA into subcellular compartments using the gene gun precludes any escape of introduced foreign genes through pollen grains.

The Gene Gun has already been used to genetically engineer cereal crops, such as maize (corn), rice, wheat, and oats, as well as numerous dicotyledonous plants, such as soybean, tobacco and certain trees. In addition, the Gene Gun has been used to transform animals and fungi.

Many of the plant crops currently grown in Alabama are produced at or near their genetic potential. Other crops are limited because of pest or climatic problems. Gene manipulation is an efficient way to increase production without dramatically changing the current regulations or increasing the cost of production.

While this technology is new, the concept of genetic engineering has been used for generations. In the past, this has been accomplished through selective crossbreeding of animals or plants to enhance beneficial characteristics. This and other new genetic engineering technologies offer faster, more precise methods to achieve this goal.
