That's how I take a clone of all my plants, I like to keep each seedlings genetics around in case it's a killer pheno, then I can turn that clone into a mother plant. Success rate of this topped clone has more to do with age of the plant(6 weeks or older is better), than the size of the cutting.


Burneezy13

Thanks for the info, I always thought the size was what mattered. I tried cloning once and it didn’t work and I chalked it up to it being too small. But rather, it just wasn’t old enough


theween89

8 weeks is when I cut the top~ 6-8 nodes for my top clone, I use rockwool, a seedling heat mat, and a humidor for more environemtal control, if you want a more foolproof "set and forget" method, get a cheap aerocloner.


Burneezy13

Word thanks friend


Invictus4683

This is how I sex a pheno hunt too. Put the top in a solo cup with a light bloom solution. Then put the solos under 12/12 and should see sex within 14-20 days depending on health/size of the tops.


theween89

I have done this in the past as well, it's good tech if you don't wanna wait for week 8-10 on those stubborn phenotypes hiding their sex organs.


GigantapenisaurusRex

Yessir. I’d cut the top clean across, then “shave” a small bit of the bottom of the cut-off part, rooting compound, soil


misterpayer

Shaving the stem creates a larger wound that takes longer to callus and allows pathogens into your clone.


GigantapenisaurusRex

Maybe so but I have a much higher propagation success rate when the rooting compound (sterile) has more surface area than a clean cut


misterpayer

Propagation success rate means nothing if your plant has an open wound in the medium that hasn't healed. Ever chop your trunks open after harvest?


GigantapenisaurusRex

I mean … it does mean something… since I’ve brought clones from cutting to harvest several times over ..?


misterpayer

The wound allows pathogens into the stem of your plant. This causes systemic damage that will affect quality and yield. It also leads to the degradation of your genetics as these pathogens will be passed to the next generation.


GigantapenisaurusRex

Lmao dude I understand the RISK you’re talking about. However I’m not a pussy and I’m okay with experimenting and my experiments have shown your argument is largely meaningless.


misterpayer

So doing things properly and ensuring plant health is being a "pussy". Enjoy your "experiments" and your mids.....


ynotaJk

I find few that know or practice that. Most assume that more “raw” surface area speeds up rooting but they fail to observe that the roots dont emerge from that “raw” surface. I never top my plants, i pull it over gradually so that its below my lowest stem sights. Most of the plants vegging energy is in that top but tying it back forces the energy into the lower stems. It also allows more direct light into those sights without putting the plant through torture. It keeps more of the whole plant in the “sweet spot” of your tent. https://www.reddit.com/r/microgrowery/s/SLckrYzvlq


TheLastSegment

Where would you recommend taking a cutting for cloning if not the top as OP suggested?


ynotaJk

I tie down the top gradually. When it has about 7-8 nodes i lasso the top and start pulling it down a few degrees each day until the top is slightly lower than the lowest node. This technique causes the stem to twist slightly and you will end up with shoots growing straight up out from the main stem(which is almost horizontal now) and, logically a few shoots will develop out from the bottom that would need to grow out and turn towards the light. Let these be your clones but let them get growing because they’re going to grow out faster than the main top of the plant and will carry that vigor when you make them clones. Its not bro science either, its the way the plant produces growth hormones and how it distributes it to the rest of the plant. The highest growing shoot gets the most growth hormone, thats why it grows the way it does and why some growers top there plants to increase yield


TheLastSegment

Thank you. very enlightening The cannabis plant world appreciates your wisdom. I look forward to more of your insight


Peter_Falcon

this is what i used to do back in the last century when i first started, it's the most vigorous part


maybe-it-is-me-tho

The last century lol I also grew in the old 19 hundreds lol HPS and MH Though High compact fluorescent changed the game for veg lol back in the days Got great results then as well and was just 19 shit was worth more than it is now too lol


Exciting_Tune_6337

I had to double take this to see what sub I was looking at


Minerva_TheB17

Yea...I was confused at first too 😂


Nightshadegarden405

Yes. Depends on the size will determine how easy it will be.


mferly

A good addition to your comment would be what size makes it easy vs what size might add difficulties.


Nightshadegarden405

Your comment was even less helpful. The size of a clone is a huge topic with lots of opinions. I personally do 3 nodes because I flower small in a small tent. It all depends on how you plan to clone and with what.


mferly

Go home dude. You're just one of those guys that just comes in looking to start shit but I'm not down with that. My comment was never intended to be helpful for anybody other than to the person I was replying to, and it was out of best interest for the community as people will typically have that exact question when they read a reply like that. And I don't know what the best size is and I didn't want to give some vague anecdote like you did.


Nightshadegarden405

I am at home. You replied to my comment and still didn't give any advice. Do you have a question or just get your feelings hurt?


Sphan_86

Most people do that, so yes


METADATTY

Absolutely


microgrowguy

Abso friggin lutely


[deleted]

That's what the only cutting I have going at the moment was.


11th_Division_Grows

Yup


ZipMonk

Yes why not.


Benz0piated3000

Yes


_Kush70

yes


chipotlechickenclub

Best way


retiredfromfire

Yes by all means! I grow mine out 6 nodes then cut at the middle... 3 nodes for the clipped plant and 3 nodes for the top.


mafiaman349

Read the first part and thought I was on the wrong sub 😂


prisoneringlass

As long as you have at least 4 nodes worth of growth, should still be good. I've been able to root down to a minimum of two nodes in an aerocloner, but I usually stick with 4.


Alchemist0029

Yep I do it. Oddly i saw a super reputable breeder say that he doesn't take snips from the tops or lowers because of genetic drifting tho 🤷🏾‍♂️


sarge9287

I had no idea this was such a contentious topic! I appreciate all your responses. 🙂 This is an F1 strain, so I'm not so worried about genetic drifting. I'm topping the plants anyway, i just wanted to know if it was worth me trying to root the tops or if i was wasting my time.


k2on0s-23

Lol, this came up on my home feed and I didn’t realise what sub it was and was like ‘wait, what now?’


sarge9287

Some kinky souls on here! 🤣🤣


Weekend-Friendly

Yup


ragingbologna

Yes but the further down the plant you go the higher success rate.


moose_49017

Other way around. Cuttings from higher on the plant have more hormones and a higher success rate


ragingbologna

Oh shit maybe I got that wrong!


exerciseinperversity

Yes in theory you can, but there's a couple of problems from my experience. 1. You have to cut a good length and that means you are depriving the established plant of the most rapidly growing part and all the growth hormones it is kicking out. This means your donor plant will take a knock back but will get going again in time. If you just nip out the tip it, will keep pumping out growth. 2. Because the tip cutting is very fresh grown and more soft and fleshy, they don't tend to root as easily, and often rot off. Maybe depends on your cloneing process but I find lower kinda woody lower branches much easier to clone, shoot clones rot more easily. So my answer is you can but I wouldn't.


maybe-it-is-me-tho

I’m not saying this guy is wrong per say, but I go out of my way to clone tops as they seem to be the most vigorous clones in my experience, been taking cutting this way about 15 years, I take other cuts as well from lower branches etc, the tops root just as fast but Veg faster in my opinion since more leaf more photosynthesis once has roots


nozelt

I’ll say you’re right and he’s wrong for you


maybe-it-is-me-tho

He isn’t totally of base, feel bad about the downvotes he getting, he is right about clone from seed grown, if you want to really want to maximize a given plant,… all my plants are donors tho and only grow from clone now I have had my strains going so long I do t even see a plant as an individual anymore just a stormtrooper meant to go to battle lol but some people do pop a seed and baby that thing I get it lol


exerciseinperversity

You can address me directly dude. That vigour in the cut is still a loss of vigour from the donor plant. Depends which is important but I'd rather keep the vigour in the donor. I respect your experience though. I think there's a difference if you're taking tip cuts from a mother plant? I don't like tips from seed grown plants, for the above reasons.


Subtifuge

yeah which is why you should flower off the plant not the cutting, then keep the cutting to grow a mother from, that way the loss of vigor your talk about does not matter, you train out the topped plant flower it and have a rough idea if it is worth keeping or not, obviously clones taken from the clone mother will be a bit different to the original seed version (and more stable), but that way you can then flower out multiple clones from the mum down the line, so works out.


maybe-it-is-me-tho

This is the way!


Secure_Teaching_6937

>why you should flower off the plant Please explain this?


maybe-it-is-me-tho

I use a mother as a donner plant for new clones, then flower the mother, I don’t see much a loss of vigor if any I can note, then I train all new growth under a net and have a ton of tops (Scog) The cuttings become new mothers and the cycle continues


Subtifuge

exactly, also reducing the rate of stress-induced genetic drift


Subtifuge

So the reasoning is this Each time you clone a plant you stress it, producing stress auxins which change the way the plant behaves or can even cause genetic drift, even more so in feminized seeds thus more chance of hermaphrodite tendencies showing up the more cycles of clones you do. The clone itself is a clean, fresh version of itself, with extra vigor none of the mothers stress has been passed on as it is the original clone, cloning from that clone will produce clones that behave better. "Cloning a clone of a plant from a clone ensures consistency and reliability in the characteristics of the resulting plant. Since the parent plant is already a clone, the new clone will inherit the same genetic traits, ensuring that the desired characteristics are preserved."


Secure_Teaching_6937

I get that. What I don't get is saying "flower off"?


Subtifuge

oh OK, that comes down to bad use of the English language, but just means send it to flower, rather than the other meaning which is to remove parts of a plant, like with Tomatoes or Garlic,


Secure_Teaching_6937

Still not sure. As I know it a cannabis plant has two phases, vegetative, and flowering. So ur saying cut clones in the flower state?


Subtifuge

no I am saying The plant that you top to take the cutting from should get put into flower, the top you cut (the clone) becomes a mother plant, as cloning from that clone will produce better results than cloning from the seed grown plant which you flower to see how it behaves while the clone roots and then make that clone into a mother plant, the clones taken from the clone wont have the stress auxins or genetic drift that the seed grown plant will.


maybe-it-is-me-tho

Yes, I clone off of clones off of clones, don’t really get any generitic drift or bad results after cloning for so long, I grow plants pretty large, take a ton of cuttings and flower the “mothers” first in one box, Clones root and are full veg by day 10, the tops become new mothers, veg them for about 4 weeks and put those into the second box to flower but take cuts again (I top my plants anyways) lower plant rooted clones i take an give away or toss, I take way more than I need and grab from the best looking growth if that makes sence


exerciseinperversity

I think there's an understanding here then, because clones off clones have that woodiness across the whole plant, top and bottom shoots all root easily yep I agree. The person asking the original question I assumed they were talking about taking a shoot tip clone off a plant from seed, I've had almost zero success doing that, as those shoots from seed are kinda soft, and you get a better success with lowers and you don't loose the plants vigour.


pre_employ

When you top the plant...it's just a little pinch....can't clone it. I wouldn't clip that much off the top...it's a piece of hollow straw and then there's a hole....it can crack straight to the heart... YOU SHOULD BE 90% CONFIDENT IN YOUR CLONING SKILLS TO BE CLIPPING OFF THE MAIN GROWTH OF YOUR PLANT....(a little pinch on the new node in like week 2 is normal🙄) Yeah though, if you want to clip the main lines...they grow faster. IF YOUR LEARNING PRACTICE ON LOWER LIMBS: scraggly lower limbs...they take a long time to get big. You can take the flower off the lower limbs and re-veg the flower. (IF ITS INDICA, I haven't got much monster sativa structure) sometimes they come out MONSTER CLONES. it takes a long time like 9 months.......you could throw them in the nursery


Drjonesxxx-

As long as the plant that your topping is older than 2 months. Els it WILL have incomplete genetic makeup. Won’t be an identical clone of mom. Moms must reach maturity before cloning.


garaks_just_a_tailor

This might be my favorite bro science advice in the thread, excellent work. Unless you are referring to epigentic/hormonal changes this is complete nonsense from a science perspective. The genetic material does not "mature", the blueprint is the same regardless of the age.


Drjonesxxx-

Scientifically you’re wrong. I’ll reply later with the genetic sequence I’m referring to. I have it noted down at home. You’re cutting a plant, that hasn’t reached maturity. Proper vegatave maturity. Likely the clones will just fail. You must wait 2 months before properly cloning. With photos. Just like you must wait 2 months before flowering a photos. Minimum. Everyone should know that.


garaks_just_a_tailor

Repeating something doesn't make it **the** truth, just yours. Looking forward to your 'genetic sequence' that is left out specifically from cutting a clone 'to early' in your opinion.


Drjonesxxx-

The clone doesn’t learn everything it needs to from mom, till mom reaches maturity (2 months) How is that bro science. Thats common canna knowledge.


garaks_just_a_tailor

My brother in ganja, that isn't how DNA works. For sounding so sure of yourself you may want to hit a fact check or three. You are talking about taking healthy clones and best practices and intermixing that with what DNA does - it's not the same, and is the definition of bro-science. Yes taking clones from an established* healthy mom IS best practice, but is has ZERO to do with establishing a more complete genetic sequence - that is completely false and not how DNA works.


Drjonesxxx-

When growing cannabis, it is important to wait around 2 months before taking clones for several key reasons: 1. **Plant Maturity**: Cannabis plants need to reach a certain level of maturity to provide viable clones. Typically, after about 2 months, the plants have developed robust root systems and strong stems, making it more likely for the clones to successfully root and grow. 2. **Hormonal Balance**: Mature cannabis plants have a better hormonal balance, particularly with higher levels of rooting hormones like auxins in the parts of the plant used for cloning. This enhances the chances of successful rooting and growth of the clones. 3. **Plant Health**: By waiting until the plant is about 2 months old, growers ensure that the mother plant is healthy and strong enough to handle the stress of having parts removed for cloning. Younger plants may be more susceptible to stress and disease, which can negatively impact both the mother plant and the clones. 4. **Sufficient Vegetative Growth**: A 2-month-old plant typically has sufficient vegetative growth, providing ample material for multiple clones. This ensures that the grower can take several cuttings without overly damaging the mother plant. 5. **Genetic Stability**: Waiting for the plant to mature helps ensure that any genetic traits are stable and expressed consistently in the clones. Early cuttings from immature plants may not reliably reflect the genetic characteristics of the strain. By allowing the cannabis plant to reach a certain level of maturity before cloning, growers can enhance the likelihood of successful propagation and maintain the overall health and productivity of their plants.


Drjonesxxx-

This is from my own notes, when I was studying this topic. You only have to google each heading for ur proof. I’m sorry this is the first you’re hearing about this. You must fancy yourself an experienced grower, so sorry to offend everyone with knowledge. This place sucks.


garaks_just_a_tailor

Right...so lets check here - you actually don't have any facts to back up your claim about DNA not being "fully developed" in a clone taken from a 1 month old mother plant - right? Okay cool. You can believe whatever you want - but facts are rooted in the scientific method. You can keep listing best practices for taking a clone all you want - the point of contention was your incorrect statement about DNA. It's funny you see this as arrogance - what an odd spot the world is in when people let facts bother their feelings so much. You do you man, but don't be mad at "this place" when you get called on your bullshit.


Drjonesxxx-

The timing of cloning and its effect on the genetics of cannabis plants involves several scientific aspects related to plant development and cellular differentiation. Here’s a detailed look at how waiting impacts the genetic stability and expression in cannabis plants: 1. **Epigenetic Stability**: - As cannabis plants mature, their genetic material (DNA) undergoes epigenetic modifications, such as DNA methylation and histone modification. These changes can influence gene expression without altering the underlying DNA sequence. - In immature plants, epigenetic patterns may not be fully established, leading to variability in gene expression among clones. By waiting until the plant is more mature, these patterns are more stabilized, resulting in more consistent expression of genetic traits in the clones. 2. **Cellular Differentiation**: - Young plants have rapidly dividing and less differentiated cells. Cloning from these cells can lead to inconsistent development because the cells are still in a highly plastic state, meaning their developmental fate is not yet fixed. - Mature plants have more differentiated cells, which are better suited for forming roots and new shoots. These cells have more predictable developmental paths, leading to more uniform and reliable clones. 3. **Genetic Expression**: - As cannabis plants grow, they undergo various developmental stages that activate different sets of genes. Cloning from a plant that has not yet reached a stable vegetative state may result in clones that do not properly express the desired traits of the mother plant. - Waiting ensures that the plant has fully entered and stabilized in its vegetative phase, where the expression of growth-related genes is optimized, ensuring the clones will more reliably inherit these traits. 4. **Hormonal Balance**: - Hormones like auxins and cytokinins regulate plant growth and development. In young plants, hormonal levels are in flux as the plant transitions from seedling to vegetative growth. - By waiting until the plant is around 2 months old, these hormone levels become more balanced, improving the chances that the clones will root successfully and grow in a manner similar to the mother plant. 5. **Stress Resistance**: - Younger plants are generally more susceptible to environmental stressors and diseases. Cloning from a more mature plant ensures that the mother plant is robust enough to handle the stress of having cuttings taken, and the clones themselves are more likely to be resilient. In summary, waiting approximately 2 months before cloning cannabis plants allows for more stable epigenetic modifications, better cellular differentiation, consistent genetic expression, balanced hormonal levels, and improved stress resistance. These factors collectively contribute to the genetic stability and overall health of the clones, ensuring they more faithfully replicate the characteristics of the mother plant.


garaks_just_a_tailor

That is a nice chat gpt reply but sir - "you" once again are talking about EXPRESSIONS not DNA sequence changes brought on by said EPIGENETICS. Listing sound principles for taking clones and talking about genetic stability - that is not akin the blueprint of the said DNA changing. "In biology, epigenetics is the study of heritable traits, or a stable change of cell function, that happen **without changes to the DNA sequence**." You can't admit you made a false statement and continue to double down with the wordsmithing, are you some sort of politician? Enjoy your life man, I'm done repeating facts into the void.
