Super Cropping Marijuana Plants

Super cropping is one of the best pruning techniques that you have available to you. It’s also one of the easiest to perform. It isn’t like pure pruning where you actually snip off some of the plant. Instead, it’s more like putting the plant through a little bit of stress to get it to increase yields. The basic crux behind super cropping is that you are trying to increase the number of “tops.” You want to push the lower growth higher and wider so that it will flower.

This technique essentially allows you to take the auxins (or growth hormones) and detour them from growing tips to other areas where they can maximize growth. This is a technique that can be performed on virtually every plant (excluding autos) and you can actually do it multiple times during the vegetative process. This allows the nutrients to work double duty, producing much heavier yields in areas that wouldn’t have been particularly productive. The plants themselves tend to look bushier and more robust as a result of super cropping. Download my free  grow bible for more marijuana pruning techniques

How to Super Crop

(Note: Not all plants will react the same to super cropping, so it’s important that you test it out on a few branches prior to taking on the whole plant).

The goal here is to essentially make the plant think it doesn’t have a top. This allows lower growth to expand upwards in the place of some of the branches in the top canopy. To perform a super crop, you don’t need any special tools or devices. It’s a really simple process that only requires a thumb and a forefinger.

First, you’ll want to find a plant that’s ready for super cropping. Generally, anything that has advanced past seedling stage or is about 3 or 4 weeks old should be eligible for super cropping.

Then, you need to pick a specific point (generally near the 1st and 3rd node sets) where you want to create an imaginary horizontal line of “damage.” This point really depends a lot on the spacing of the plant. Everything below that horizontal line will start to gain nutrients at a faster rate.

    Once you’ve picked the horizontal line, you need to take your thumb and forefinger and squeeze at that location. You should do this for virtually every branch if you think the plant can withstand a full super cropping. You should squeeze at a uniform point, turning you’re the branch about 90 degrees every time. The tops themselves should end up folded over. You don’t want to be too firm to the point where you break the branch entirely off, but you also don’t want to be too lenient to where the plant regains its vertical posture within a matter of hours.

    Over time, the point where you “broke” the branch will start to heal. Again, you don’t want to snap the branch entirely off. You just want to bend it (like a kink in a hose) and then let it flop over.

      1. Is it necessary or wise to super crop as well as top, or is that overkill? If I did do both, would it be less stressful to just do it all at once, or would that kill it? I’ve seen plants mown over by a tractor go on to heal and thrive… I’ve only ever used LST so this makes me nervous.

      2. How late in the season can I super crop? My girls are outside and are growing like weeds. I just want to stop them from growing over the fence. My girls are lemon tree and forbidden fruit

      3. Ive been growing since the mid 90s in my teens i took all knowladge from moms old friend and new tech combining old skool with new i rember seeing 10 ft tall plants in mid to late 80s as a kid first plant were froms moms bag i stole it grew better then what she was buying its not the plant its how you care for it for maxium out put and potancy i srarted a plant back inlate september out door then moved indoor under a 215w t5 with a 100w led cob light about 4 ft across and 3 ft high in the 12/12 cycle and now with currently my state leagle no worrys on growing

      4. Hi Kelly,

        I’m sorry to hear you have trouble receiving the downloads. I will send you a email containing the direct PDF files to make it easier for you!

      5. I have tried to get your grow guide and harvest guide. I have filled out your forms 10 or more times now and have not gotten anything. I have even tried the download the odd now form. Still nothing. What’s up with that. By what I see in your comments, I am not the only one that has problems with these downloads. Why does everyone seem to have a problem with these down loads. You can’t fix them so they work right? Some of them are rather old and one would think you would have towed it by now. Makes me wonder why you haven’t and if this is a site I can trust. I have girl Scott cookies 8-18 days from harvest. The seed pods are filling up. The hairs are starting to die back on the lower parts of the buds. The trachomes are still clear and the plants look like they have been snowed on. The seed pods are filling with THC and getting fat.

      6. Kay,

        You should allow an auto flower (all are fems), to grow naturally. Since the plant is meant to be a short term grower in the fastest amount of time; It makes no sense to stress the plant, at all!. In general; We do not clone autos. We do not top autos. We do not stress in any way, if possible in order to allow the genetics to do the job. 🙂

        If you want to try this method, then I recommend you buy feminized strains next time. Happy growing. Feel free to join our support forum.

      7. I’ve received 30 x excellent looking seeds from ILGM. 9 have been started and they’re now growing well outdoors (Australia) after 16 days. Since they are auto-fems (hybrids), should I be considering this supercrop method, or is auto a definite contraindication?

      8. Hey there Robert
        Wow such a plethora of info on growing tips , harvesting , curing and the selections of seeds is awesome .I am a first time grower and just ordered some “Crush” or Snoop Doggs claims it s green crack yeah you just want more lol.I found you through a friendly grower and fellow “Old School Stoner” he and i built our ownn closet for the mother plant which is now just hanging out drying .He bought some WW from your place.we are about to germinate them now .He gave me two of his 9 babies and we harvested them yesterday.I bought a grow closet where I plan to put 3 of the 5 I ordered then I might try one outside.oh BTW we live in East Texas nice and hot humid and green here .Well I wanted to say thank you for your site and I cant wait to start these babies.Estatic actually lol. I will give your site 9 out of ten points , i gotta leave room for improvement because im sure you will!!! It really is a big ten plus really.

      9. It is not so much about letting the plant heal before starting the flowering period, as it is about being careful while supercropping as not to break the skin of the stem that is being bent by gently crushing or pinching the stem at the point where you want it to bend. If you break open the skin you make the plant more vulnerable to damage or disease — because of easy access to the inside of the plant from insects or mold and fungi. If you do break open the skin you want to bandage it, not unlike an open wound on your own body. You can wrap the damaged area with duct tape, electric tape or even a special tape from a local garden supplier. The tape can probably be removed after a few days when the wound has scabbed over. If needed you can add a brace using tooth picks, popsicle sticks or even wire or plastic straws or rods. In most cases only a couple of days are need for recovery but some strains may require up to 4 weeks. For some growers it is a matter of “style” or just a personal preference, but in actuality most people continue to supercrop well into flowering, at least until the plant stops stretching around 3-5 weeks after initiating the flowering period. For most people, the topping and training are all about developing the largest buds, and so they continue to cut and remove parts of the plant that are not getting direct light, anything under the “martini” or “lollipop” shaped canopy is removed, even small nuggets aka popcorn buds until the stretch has stopped.

      10. after supercropping how long till the plant could go into 12/12 for flowering for best results?
