In other words, when you clone a sick plant, chances are good the clones will be sick, too. A good rule of thumb is to closely examine a potential donor plant a few days prior to cloning for insect damage, molds or fungus , and check the overall health of the leaves.
Ideally, a donor plant is in the vegetative stage of growth. Donor plants reverted from the flowering stage are acceptable and, in some cases, actually preferred. It is also acceptable to take clones off a lower section of a plant as it enters the first stages of fruiting and flowering.
Clones taken from a donor plant that is too far along in its fruiting or flowering stage will usually result in low success rates.
One way to increase cloning success is lessening the light intensity on the donor plant 24 hours prior to taking clones. This can be done by lifting the lights farther from the plant canopy or by placing the donor plant in a low-lighted area. You are essentially allowing the plant a little rest and reducing the stress that can sometimes accompany rigorous growth under intense artificial lighting. Cutting tomato plant for cloning.
Once the donor plant is selected, the grower can prepare to cut clones. Personal preference will play a part in the size of the cutting a grower will take.
Different growers have different methods when it comes to the way they cut clones. Some growers make the final cut underwater, first cutting the stem to remove from the donor plant and then, subsequently, making a cut underwater to avoid an air embolism. I never got into the whole underwater cutting thing. I have always had high success rates by simply cutting the stem at a degree angle, right at or right above a node.
I prepare my cloning gel in advance so I can immediately dip the clone once the degree angle cut has been made. There are many different cloning gels and powders on the market and they all seem to do a pretty good job.
In a recent experiment, I decided to try using honey as my cloning gel. To my surprise, clones rooted just as fast with as high a rate of success as with a cloning gel. For the grower on a budget or big into organics, honey should be tried as a cloning gel. Plant cutting in fertilized soil. Source: Shutterstock. Again, it becomes a matter of personal preference for the medium chosen.
I have successfully rooted clones in stonewool , hydroton, soil, various soilless mixes, pumice, perlite , vermiculite and sand. My personal favorite is stonewool. In other words, a slightly acidic solution should be run through the medium to bring the pH slightly below 7. The medium used for cloning should be kept moist but not soaked. A well-aerated medium for cloning can make or break it once the initial rooting begins. It is also a good idea to provide a small amount of food when clones begin to root.
There are many different specialized cloning conditioners rooting solutions that will provide small sustenance for plants with emerging roots.
A diluted bloom fertilizer about one-quarter of the regular dosage can be used as a substitute in a pinch. Foam cloners for aeroponics. Growers who use an aeroponic cloner will not need to condition the medium for cloning. Once the clone is taken and the rooting gel has been applied, the clone can be placed in the machine. I have been a comercial grower for 18 years. I cut clones on a weekly basis.
In my opinion keep it simple. I dont use any special nutrients for my mothers. I keep up on my spraying neet for pests.
I dont use razors or cut under wanter or any of that. Just scissors at a 45 and dip in rooting powder stem root 2. I use jiffy 7 pucks and domes unde 24 flouresent light. I open the dome 10 minutes per day for air. I also make sure my pucks are not too wet but just the right amount of mousture. By this method I have produced clones every month for the last 5 years. I would bother with the expensive additives or any of Keep it simple. Post reply.

Top Bottom. There is some speculation that clones can degrade over time based on environment stressors and other factors, but that is open to debate. A mother plant is any cannabis plant you take a clone from. Mothers should be healthy and sturdy, as their genetics will pass on to the clones—if you have a sickly mother plant, its clones will also be sickly. Mother plants always stay in the vegetative stage as clones are clipped off. If your grow space is tight, this might not be the best setup.
Another method growers employ is to take cuttings off a set of mother plants before they flower, then flip the mothers into the flowering stage. The next generation of clones is grown, and when those get big enough, cuttings will be taken from those before getting flipped into flower.
Because clones are genetically identical, each generation will be an exact copy of the first-generation mother and all subsequent mothers. Cannabis mother plants guarantee genetic consistency, so each new generation of clones taken will have the same taste, flavor, effects, and other characteristics. Clones will also generally grow at the same rate as the mother, produce a similar quality product, and grow with the same vigor, allowing you to dial in your process and really get to know how to grow that particular weed plant.
Common rooting mediums include rooting cubes, rockwool, or other non-soil equivalents like peat or foam. Rockwool is melted rock that has been spun into a fine thread, and it has terrific airflow and moisture retention. You can find any of these cubes at most grow stores or online.
The clones will go in the cubes, the cubes into the tray-cells, and all of that sits in a tray which will hold water. To keep in humidity, make sure to use a dome over your tray, and you may even want to use a heat mat. Another method is to use an auto-cloner. CFL lights will not burn your plants as long as you keep them around inches from the leaves. You can also use HID lamps, but make sure they stay a safe distance from the rooting system or individual cuttings.
Indirect sun from the window is also a good idea if you keep your cuttings in a warm place. Some growers make the decision to not use any lights at all for a day or two while the clones are adjusting to their new surroundings. Others start with a bright light and then use a dimmer grow light after a couple of days.
For roots to form, there should be at least some darkness each day. Try 18 hours of light and 6 hours of darkness. A mechanized cloner can also help automate some of the processes if you are willing to invest a bit. The cloner will do it for you. Cuttings can come from mother plants that are as young as two months old.
They can also come from flowering plants. If you take a cutting from a flowering plant, use the less mature buds. These can be found on the part of the plant that stays shaded.
Then, simply remove those baby buds, since they are going to die anyway. Do not clone plants that have already reached their second week of flowering. Stay clear of woody stems when you are selecting your clones. The harder the stem, the more difficult it is for the clone to start rooting. Select your medium and place your cuttings in it.
Give them 10 to 14 hours of light daily. It is difficult to root cuttings taken from a flowering plant, and it typically takes longer if successful. Give it time before you throw in the towel. Once rooted, clones from flowering plants will behave a bit differently. However, as long as you maintain lighting and good conditions, they will look more normal after a couple of weeks.
When successful, these types of clones tend to be bushier than their mothers. Clones rooted in soil or Rockwool are transplanted just like any other marijuana plant. Once they have rooted, remove them from their dome or tent if you used one and transport them to their new homes. However, water-rooted clones require a slightly different method. To transplant into the Earth for outdoor growing, dig a one-foot deep by one-foot wide hole.
Then carry the entire container holding the rooted plant, including its water, all the way to the site where you will transplant it. It is important to remember that, regardless of how inconvenient it is, you should not expose the roots to air while transporting it to its new home. If moving into a pot, prepare the container with your growing medium before moving the clone. Try and maintain the same climate while transporting your clones. For every method, the final step is gently placing the plant in the hole and fill it with potting soil.
If you are growing outdoors, mix potting soil into the dirt. Pat down the soil firmly but gently, then water the entire area with a half-gallon or more of water mixed with plant food. In general, clones that have already taken root have a very high chance of survival. This is simply because the original plant they were a part of were already mature and strong, meaning that a clone with roots is no different. You can extend the vegetative stage if growing indoors.
Keep your eye on your plants once they begin to flower. While clones are genetic replicas, marijuana plants are hermaphrodites. You can buy clones at any age, but if you are ready to plant, you want clones with good roots. If you are buying a cutting that does not have a good root system yet, make sure that it has at least a couple of nodes on it, so that those roots will be able to form. If you take a cutting from an autoflower, your yields will be significantly lower. This is because the clone will not have that much time to grow more buds.
Since it is autoflowering like its mother, it will simply continue the flowering stage with fewer buds instead of reverting into a temporary veg stage like non-autoflowering plants. It causes the plant to shift more of its energy underground and seek out nutrients from its roots rather than the parts existing above ground. In general, this process is a bad thing, however, when you are trying to grow roots, a little of this can be good. Clones are ready to transplant once they are fully rooted.
You can place your clones outside late Spring but wait until it is at least 50 degrees Fahrenheit. You should also make sure there is enough time left in the season for your plant to continue growing in size before it flowers, or else, keep it inside under lights. For more on scheduling your outdoor grow, read my Outdoor Grow Calendar. When you create your own clones, you need to make sure the roots that develop are strong enough to support it.
One way to encourage strong root production is to keep your cuttings away from light. Remember, roots normally form in the dark, moist environment of dirt. Your cuttings will need something similar.

I cloned a mother plant that was about 3 months old, I got 3 healthy clones started in buckets which I keep outside during the day and give them about 12 hours of sun and then place them back inside in a completely dark room with 2 fans going constantly..
Thanks mega millions??! Thanks heaps again. Do you actually clip the leaves of the cutting at the time of putting it in root gel then medium? Very informative thank you……. I learned from my dad. Hi Brian, thanks for the heads up. We still keep track of comments regularly so I will have our team elaborate on the loose end. Thanks again! I also posted a question asking for clarification. Hi Neil, he mentioned in the article that over time each generation is more susceptible to disease.
Other authors also mention genetic defects leaves curling sideways, triplet nodes, etc increase in likelihood with each cloned generation.
Can you please elaborate? I cloned about Why would you give a clone flowering fertilizer? Cloning actually can help increase potency because the plant adapts to your method of growing and potentially has less stress.
Rena, I am not sure what you mean by wrap. I went through the article and could not find mention of wrapping anything. We can reach you a lot better in the support forum of ILGM. Burley, It is hard for us to say where you sliced the cuttings. Best to join our support forum, and we can show you how to clone successfully. Bill, join us here: support. Old seeds that are dormant can take a lot longer to germinate.
Thank you. Did I cut them too high on the mother plant? I had seeds germinated after over a week. Just give them time. How do germinate old seeds i have tried soaking them in water with hydrogen peroxide for 24 hours and suger water for 48 hours then in the paper towel thing and still nothing. Tired of wasting some good seeds can you help me. This is some incredible information. I will be ordering seeds in a few days so I plan to go all out and take this process as far as I can.
I suggest you download and read our free grow bible. Unless you are breeding you do not want to pollinate and produce seeds. Seeded plants are low in THC due to spending all the energy producing seeds.
We clone because genetically we have a plant that once rooted is the same age as the Mother plant, and can be vegetated in weeks and flowered cutting off one month of grow time; Approximately. We also can expect all clones to be the same size as the next one taken form the same Mother.
Evidently you did something wrong. Try one of the proven methods described here and if you continue to fail, come see us at support. Evidently something was wrong or you would have succeeded. Keep trying. Perhaps do as desecribed in one of the fool proof methods above. Join us at: [email protected] if you have any more issues. We have a friendly staff and sharing members, always willing to help. The longer you veg the larger yield you will have. I am very naive about this.
Why clone if your plant produces seeds?
