Monster Cropping Marijuana Plants


monster cropping marijuana plants

Monster Cropping (a.k.a. Flowering Clones) is new method of growing that one of our members brought to my attention. Monster Cropping essentially involves taking clones from flowering marijuana plants, and then rooting those clones. They will reenter vegetative state and eventually create super-bushy plants with a large amount of nodes and branches. This method was dubbed “Monster Cropping,” because that’s exactly what you’ll end up with—huge, monster plants.

Flowering plants typically aren’t a source for clones, and most experts will tell you that it goes against most rules of cannabis cultivation. Even so, the science behind Monster Cropping is legitimate, and you will certainly enjoy the results.

Start by taking clones of a marijuana plant that is about 3 weeks (21 days) into the flowering stage. This is usually the ideal time to take the clones, but you can also take clones later on without affecting the results. Lower branches are ideal for cloning because they haven’t become stiff, and they will root faster than something like the top cola. Take the cutting and place it in a glass of water. Let it sit there for some time so that no air finds its way into the vascular system (a problem that can be fatal for the plant). The cut needs to be made along the stem so as to increase the surface area for the uptake of water and/or nutrients (depending on the cloning technique you’re using). In my own experience, a small hydroponic system or a propagation bubbler is easily the best option for cloning marijuana plants. Download my free marijuana grow bible for more tips about growing marijuana plants.

You will have to go back to a vegetative light schedule for the clone (18/6, 20/4, or 24/0). These clones won’t need much light, and you can get away with using a single small CFL bulb. Removing buds at this point will encourage the plant to go back to the vegetative state, but do not mess with the flower on the apex.

The clones should root in several weeks’ time, but some will never take root. To combat this, make sure you take a large number of clones so that at least one will take root and survive. You may want to put the clones inside of a humidity dome. These can be found at gardening centers or you can custom build one to meet your own needs. The increased humidity of the dome ensures that the plants won’t dry out, wither, and die. Be sure to ventilate the dome each day to avoid a mold infestation.

The most important aspect of cloning is to give the cuttings enough oxygen. A propagation bubbler is perfect for doing just that.

The marijuana clones won’t be anything spectacular to begin with, but, when they root, they will start reverting into vegetative state. The clones will start growing once they’ve rooted adequately, and they will produce single un-serrated leaves to begin with. Normal leaves will start to follow soon after. Applying some training might be wise during this stage. Simply tie down some of the tops to encourage an increase in branching. Adding a little heat underneath the clones will increase the rate of the rooting process substantially.

As the marijuana plant starts to grow, the amazing branching power of your flowering clone makes itself known. The plants will turn into genuine monsters, and you don’t even have to top the plant. The great thing about this method is that you can avoid topping and fimming altogether because the flowering clone produces tons of new branches on its own.

This plant is ready for a SCROG or maybe a SOG technique. This single plant can take up all the space in a SCROG net in a relatively short amount of time. Many of the plants grown in SOG will certainly provide a bountiful harvest.

Another benefit to Monster Cropping is that you don’t have to keep any mother plants around. When the clones go through vegetative state and enter flowering stage, they can give you even more clones. The never-ending harvest is recycling at its most efficient. For anyone who needs to limit the amount of plants they have, this idea has significant merit.

All in all, the effectiveness of this technique is largely due to the heavy branching produced by flowering clones that have reentered vegetative state. With some practice and patience, you can get some fantastic monster plants and a gargantuan monster harvest.

  1. I got 5 cuttings from flowering plants took them 2 weeks ago the bigger leaves yellowed and fell of now I got like little sticks with 2 or 3 nodes with little tips a few pistols not many it looks a nice dark green and they look alive but they have not grown atal when will they start to gro

  2. I root in 8-12 days,usually in 10 days on average and I am on a 10week rotation

  3. I would have to disagree also Ralf. I did this by accident the first time, I waited too long to take clones and my girls went into flower, I figured what the hell and rooted several clones. Within about 35-40 days my girls went crazy. Had several nugs I couldn’t even get my hand 3/4 around (biggest I EVER grew). So it does work…so do other methods. I’m one of those who doesn’t like to top, trim or cut anything unless necessary. IMHO

  4. Everyone! !!!!! Let’s get back to basics here. Firstly you can take these flowering heads (Lower supple branches) exactly the same way as you normally would. Secondly the flowering clone will take slightly longer than normal to root and revert back to the vegitve stage (around 21 days). Be patient. From personal experience most snips/cuttings that I have taken and placed in the propagator have taken with no problems. Success rate ratio is always around 85/95% successful. This method is no harder than taking normal cuttings, it just takes a little longer. Don’t look for problems everyone. Let nature take its course. The result will be ferocious growth and massive yielding plants. Less is more doing this technique. Good luck with your tomatoes. Happy harvest.

    I’m an outdoor grower. My jack horror has flowered prematurely, I think because it’s not getting enough light because it’s under my corn. so I’m thinking of taking a cutting to see if it re-enters growing phase. It’s mid summer here. Or should I just cut my corn back to let in light. Will this turn my mother plant into a monster plant?

  6. I just put these Girls into flowering one week ago and I cloned 5 today. You think it will be OK? I’m a beginner grower. I have just one yeild under my belt, not so much in quantity but the quality was really good and in one week two more Girls come down. Not as good… I’m brand new to Cannabis’s world. I sure have done my studying, thanks to the web. Haha Now I wanna hear what some experienced growers got to share with me.

  7. Antonio Gonzales on

    I like this idea. I have a question does it have to be two weeks? I ran into a problem of almost loosing genetics she was 10 days into bloom n I caught her in time to veg again?

  8. You can lst supercrop etc to get the tops to even out. Cut off inferior branches to make some space and save the tips for cloning.

  9. 100 for 1 no chance, you take 100 there will be a good 50% tht root. ive had 100% root from flower just take care of them like your babies

  10. wont take 3 months lol you’d get another grop by then. theyll take longer then normal clones but depends on conditions. 4 -5 weeks at most

  11. i wouldnt bother taking clones get a better set up first you’ll only get at most 5g off tht. or start using auto seeds for smaller setups

  12. tape em up they will heal remove the tape then there will be a nuckle that branch will be stronger then before

  13. i have to disagree-

    This was my first grow and Nov 1 I cut all the goods off and basically left a STICK FIGURE……….just for kicks I put a few lights on it and THIS is what I saw-I was SHOCKED-since I didnt take any clones the first time, would this be the time to do it?
    TIA anyone!!
    sorry for the crooked picture! the second one is the original-NOWHERE CLOSE to as bushy as the re-veg’d one!! (dang-cant add a 2nd pic but trust me the mother plant was NOWHERE near that bushy) I guess I should just let it keep on vegging?
    this is TOTAL new territory for me

    (that shot is SIXTEEN DAYS after it was a stick figure) Bushier than mama EVER was

  15. Okay guys/gals, this method sounds friigin’ fabulous, BUT, I have one question; what is the ratio of cuttings, to those that actually take root? I have SWIM that has a fem Indica plant that has been in flower for roughly ~24 days now. And was wondering if 100 cuttings are needed for 1 to root?? Also, how long is it expected, roughly, before roots start to show? Are we talking three weeks or three months?
    They have a nice humi-dome with a heat mat for the roots. Any advice form one who has actually gone through this process would be greatly appreciated. Thanks a bunch, in advance.

  16. Harry Gulliford on

    Lmao you have no clue what you are talking about i have never had popcorn buds on a plant when i clone like this and i have been for years and yielding about a pound per plant indoor so do more research and learn how to grow before u bash a badass way of cloning topping causes way to much stress on a plant if you try to make it a monster indoor

  17. the key is to use screen of green trim a lot of the lower stuff off and just have 20-50 tops if your doing it right but it is a very high risk high reward system if you want easy good pot just top it

  18. if there super late 5-6 weeks or more there’s little you can do but earlier than that with some cloning powder or gel you can reroot them given only one in three of mine took root she is an insane looking little monster now after 3 weeks of veg

  19. How do I fix weed plant branches that have buds on them that I accidentally cut off plant a little early ? Is there anything I can do like replant the branches tell they have roots

  20. So much negativity… For those that grow outside, but waited too long to take clones.
    This is a great method. Sounds to me like you need to chill out with a nice bowl of Snowcap
    there Ralf.

  21. Monstercropping is just reveg . Id much rather non preflowered clones instead of mucking about with crap like this. Easier to get bushier plants by tipping. Also whats the point of crouding out a plant cus it just makes for more popcorn. Should be called mega popcorning.

    Monstercropping dosn’t even deserve a title its that fulll of sheight.

    Funny how crap ideas actually get a foothold on the internet.

    fwiw im “monstercropping” right now due to having taken cones off sexing plants. Prefer no pistils on my clones if I had the choice.

    Monstercopping is a crock of shit

  22. Another quick tip. Cloning is very very easy and u need nothing but water and scissors.
    1st scissors don’t have to be sanitized water can be tap.
    2nd. Find a small branch that u dont care about( not the tiny flimsy ones)
    3rd. Cut it off
    4th. make another cut on an angle
    5th. dip it in water and stick it in whatever medium u use for seedlings or whatever.
    6th. Clip tips off on all of the leaves n Stick it in the shade, a shaded window, fluorescents watever. As long as it isn’t strong light and voila that’s it.

  23. No no and no. These steps may get u monster crop but there’s a much easier way.
    1st. clone any fem plant (except auto if it isn’t flowering).
    2nd. Wait till roots fully develop and u start to see plant growth.
    3rd. 12/12 the clone under fluorescents for about 2 weeks maybe 3
    4th. Add them to your veg crops(start the veg cycle on whatever light u use for veg)
    5th. Trim off buds (theyll cont to flower 1 week ,if u dont trim the flowers itll just stop growing for a very long time) smoke em if u want theyre pretty decent.
    6th. Funny lookin leaves will form and voila that’s it

  24. Great info! I cloned 4 OG Kush from a flowering plant. All I did is “nick” the stem in 3-4 places and flour in root tone, then shoved those into dirt. 3 of the 4 took, not bad for the first time. I kept them the last month in the window (Alaska, all day light right now) to “recover”. Well they are now under the light for 24 hours, the flowers are sort of gone, but all these little shoots of single leaf, like from a seed, are sprouting now. I was told that these would be bushy and so they seem to be. We will see what happens!

  25. Terrible idea, that plant looks terrible and will produce little to nothing, way too many suckers/popcorn buds. Also its not as easy as you are describing to take a clone back out of the flowering stage.

  26. How did this work out for you, Dalton? I’m really curious about whether this technique results in better flower or just more flower that is diluted strength? What did you find?

  27. Dalton Paceno on

    About to try this technique. Just took some cuttings of some pre-flowering Girl Scout Cookies. Got about 50 cuttings. These are already beastly plants. If this technique works as it says it does, these cuttings will turn into true “Monsters”

  28. Barb female farmer on

    I have recently tried this process thinking, Why Not. I had a clone in water and it budded. I have real good well water.So, I thought I would see what I could do with it. I know why they call it Monster cropping. she is now 5′ tall and has buds from the bottom of the stems at every joint in the stem, and on every leaf bottom. I will put a picture of what it looks right now. But in the AM. I also have several other clones taken from flowering plants and as you stated, the top leaves are funny-looking single leaf leaf.
    Thanks for being a great source of information. The Weed Blog Rocks

  29. Very interesting! I wish I’d known this last year, but now is better than never. What about cloning an auto flowering plant?
