If you grow cannabis, the following situation might sound familiar: Your tent is filled to the brim so your plants can collect all the light possible. Some plants are in the vegetative stage, a few are flowering, and there might even be one giant mother plant taking up lots of room, energy, and air. Let’s do something about it: Monster cropping has come to the rescue!


Monster cropping is a cannabis plant training technique that can help you grow more efficiently. In essence, it involves taking flowering clones and reverting them back to the veg phase to capitalise on dense, bushy growth.

With this method, you don’t need to keep a mother plant to ensure continuous harvests. And, when you combine it with other forms of plant training, like ScrOG, it can help increase yields even more while cutting down on energy costs. Monster cropping can be performed indoors, outdoors, or in a greenhouse.


One principle behind nearly every plant training technique is stress. If done right, this is a good thing. Controlled stress on your plants can promote desired growing characteristics; for example, it can make plants grow in a certain shape or develop more bud sites. Stress on cannabis plants encourages their natural defences into action. They go into “turbo mode” with maximum terpene production, resulting in a more aromatic final product.

Training techniques that involve damaging plants, such as pruning or taking cuttings, inflict considerable stress, and thus plants will need time to recover. Because of that, methods like monster cropping are used on photoperiod cannabis strains only.

Monster cropping differs in one important aspect from other high-stress techniques: It does not directly impact the growth of your current crop. Rather, you take clones from mature flowering plants, and these clones are then reverted back to veg.


Monster cropping may or may not work great for you. It all depends on your setup, your strains, and your experience. For instance, it doesn’t work with autoflowers and is not optimal for strains that grow very short or too slow. To help you decide whether monster cropping is worth it in your case, here are some pros and cons.


Continuous harvests and no need to keep mothers

With monster cropping, you don’t need to keep a mother plant around for continuous harvests. You are taking clones from flowering plants. You can simply start flowering your entire crop as usual, taking the next generation of clones from these. With no need for a dedicated “mother room”, you can make better use of your growing space, lights, and air.

Maximise yields

When you re-veg flowering clones, they will grow monstrous! Your re-vegged girls will become extremely bushy with more side branches. More branches with more buds exposed to your lights means bigger yields! The bushy growth also allows you to more effectively fill your grow space.

Complements other training techniques

For even better results, you can combine monster cropping with other training techniques like topping, fimming, lollipopping, or LST. This way, you can easily fill a small tent with one giant monster. For the absolute best results, combine it with a ScrOG (more on that below).


Doesn’t work with autoflowers

Autoflowers can’t be re-vegged, which means monster cropping is a no-go. On that note, taking monster crop clones from small or slow photoperiod strains isn’t the best idea either.

Not all cuttings will be successful

Compared to clones from vegging plants, clones from flowering cannabis have a lower success rate. Since some just won’t root, you should always take some extra cuttings. Even expert growers have a hard time getting all their flowering clones to root. So expect some losses.

It takes time

Cutting clones, waiting for them to root, and then re-vegging them for a few weeks means it will take longer until you can harvest your girls. So if you’re pressed for time, monster cropping may not be what you want.


It’s hard to give an exact figure on how much monster cropping can increase yields, as this relies on a variety of factors—your experience being one of them. Some growers recommend letting cuttings veg into large bushes before encouraging lateral growth with repeated topping/super cropping, and then placing them under a ScrOG. Although highly involved, this allows growers to manipulate clones to deliver the best-possible harvests.

But aside from looking at numbers alone, don’t forget that monster cropping provides another advantage: You can harvest multiple times! This by itself is a convincing argument.


It’s best to take your clones at about 2–3 weeks into flowering.

Once you have taken your flowering clones, it will take an average of one week until they root. The re-vegging of your clones will then take (at least) another 2–3 weeks. When all is said and done, expect the process to add at least 3 weeks to your plant’s growth; and this doesn’t even factor in further topping and training. Each additional topping will add around a week to your grow.


Enough with all the theory—let’s get into the practice. Here is how to monster crop cannabis indoors.


• Sharp scissors, knife, or scalpel
• Alcohol wipes (to disinfect your tools)
• Glass or container with water (to soak the cuttings)
• Rooting gel (optional)
• Rockwool cubes, perlite (optional)


At around week 2 of flowering, locate your best specimen—one that has grown well and tall. If you have multiple strains, you could select several cuttings from each one to see which plants turn out best. Make sure that the plants you’re taking from are healthy and not displaying any signs of illness or deficiency.


Take your scissors or knife and give it a quick wipe with alcohol to disinfect. Cleanliness will greatly help your cloning success! Go to your chosen flowering plant and select a lower branch. These usually root faster than branches on top. Swiftly cut diagonally across the stem to take the cutting. A diagonal cut provides more surface area for the cutting to take in water and nutrients, and for the roots to grow.

Again, make sure you take more cuttings than you need. Expect at least 25% of your clones not to root. Disinfect your tools before each cut.


Immediately after taking each cutting, place the stem into the container with water. The water will seal the cut and prevent air from entering, which would otherwise kill your clone. Alternatively, you can use a rooting gel instead of water. You can leave the cutting in the container until roots appear, or you can place it into a rooting medium such as rockwool cubes or perlite.


To get your clones back to a vegetative state, you need to adjust their light cycle accordingly. Most growers choose an 18/6 schedule, but anything from 18–24 hours of light will work. When your clones start to re-veg, they will grow in an odd way with round leaves and lots of branches. This strange growing phase will last for about 3–4 weeks.


Once your clone is in full vegetative growth again, this is when you can apply plant training (topping, super cropping) to encourage lateral growth even more. Your plants staying short and flat will be particularly advantageous if you plan to put them under a ScrOG.


Monster cropping can also be done outdoors, where it provides a major advantage: If you grow in a warm climate with no frost, you can achieve two harvests in a single season! This is how you do it.


If you bring out your seeds in winter, the longer nights will put your plants into flowering as soon as they emerge. If you want to extend the vegging period to add some size to your clones, you can supplement with a small light that you turn on for an hour or so every night. This interruption in the dark period will prevent your ladies from going into flower.

If you grow in a climate with occasional frost in winter, keep your plants indoors under a vegging light cycle, then set them outside once there is no risk of frost. If you are able to do that early enough in the year (by February in most places) they will go back into flowering before the days get long again. If it’s still too cold during this time, it’s not worth the risk of killing your ladies.


Your first batch of buds will be ready to harvest in early spring before daylight savings. At the same time that you’re filling your bags, around mid-March, the days will soon be long enough for your clones to re-veg.


Once your clones have gained mass, they will naturally progress into the flowering phase as the seasons change. This means you can harvest them at the usual time in fall. Bingo! You brought in two harvests in one growing season!

Pro tip: This outdoor monster cropping method only works in climate zones where there is no risk of frost all year long, such as in Southern Europe, Southern US, etc. It won’t work in regions where you’d need to wait until late spring to plant outside.


Monster cropping is all about maximising lateral growth from shorter plants. This makes ScrOG (screen of green) the perfect method to go with it.

Installing a net over the canopy will increase horizontal growth further as you weave branches through the mesh. The ScrOG will encourage an even canopy so your weed plants can make best use of available light. The result: tons of fat buds!


Taking clones, getting them to root, topping, and ScrOG aren’t exactly for the bloody beginner to cannabis cultivation. On the other hand, monster cropping may be just what experienced growers need to push production to the next level. It is one of the best ways to take full advantage of your available grow space.

So, if you have the skills and are not afraid to put a knife to your cannabis, you should definitely try out monster cropping. Rest assured, the results will be worth it!

Monster cropping involves taking clones from flowering cannabis plants to encourage heavy branching, high yields, and continuous harvests. Here's how to do it!

What Is Monster Cropping – A Simple Guide

What if the best high yield cultivation method was also the smartest way to take clones for the home grower? Monster cropping is the technique you need to master. If you know how to take a cutting, you’re halfway there already. But don’t worry if you can’t, we cover the whole process step by step.

Bud-Filled Bushes Vs Ganja Trees

Bushy marijuana plants with an abundance of branches are far more discreet and usually more productive than stretchy vines. Plus, they can be cloned many times without compromising the yield of the donor mother. Whether you prefer to grow your cannabis indoors or out, the primary objective is always to crop the heaviest, healthiest harvest of your strain of choice.

Pruning and training plants for maximum yield is virtually a necessity. Unless you’ve got the space and the privacy for the SOG method. When you do have winning genetics in the cannabis garden, you want to hold onto them.

Unfortunately, most home growers don’t have the space for a dedicated mother room and thus, killer phenotypes are lost. Keep reading to find out how to increase your yield and take cuttings from your best female in bloom.

What Is Monster Cropping?

In succinct, ordinary decent stoner terms, monster cropping is when you take a cutting from a donor mother during the flowering stage and then re-veg the clones. OK, this sounds pretty crazy, but just go with it.

The clones will take longer to root. Some will refuse to take root for no good reason at all. Moreover, the successful clones will be the ugliest little plants you have ever seen. Expect single finger leaves. Maybe even a few mutations. But once they take root and revert back to the vegetative stage, in a few weeks they will become monsters.

Advantages Of Monster Cropping

The two best reasons to monster crop, as mentioned in brief above, are to maximise yield and to produce killer clones. All without necessarily retaining mother plants. When you re-veg rooted clones, they will develop a monstrous appearance. In time, they will become cannabis bushes that better fill out lateral grow space.

Combine monster cropping with other pruning-for-yield techniques like LST, topping, or fimming for huge yields. You can fill out a typical 1m grow tent with a single monster plant. Furthermore, if you want to push production to the absolute limit and keep an even canopy, drop a ScrOG on your green monsters.

Provided you have a basic understanding of cloning, you can easily transfer the skill to monster cropping. This will help you better evaluate which plant is the keeper to take cuttings from. Best of all, you don’t need to maintain a mother room as you can repeat the process next grow cycle.

In fact, taking a cutting during flowering is the same process as doing it in vegetative growth. Here’s a brief recap just in case:

Use sterile, sharp scissors or a scalpel. Make a clean cut between branch and stem. Then, dunk the branch in rooting gel before you pop the cutting in a rooting cube. Finally, trim the fan leaves in half and remove the early bud material.

Disadvantages Of Monster Cropping

The biggest disadvantage with monster cropping is that you cannot apply the technique to autoflowering cannabis strains. This should be no surprise since you can’t meaningfully clone autos the normal way. Given the popularity of autoflowering cannabis, we felt obliged to mention it. We don’t want you hacking budding branches away and actually decreasing your yield.

Success rates are typically lower when you take cuttings from flowering cannabis plants. Nobody really has a good explanation why. Most growers, even the top pro’s in the game that have mastered the practice of cloning during vegetative growth, will get a few kills with monster cropping. We recommend taking a few extra cuttings as backups.

Time is always a factor when cultivating cannabis. Monster cropping is very efficient, but it will take perhaps a week longer for the clones to root. Also, they will need to be re-vegged for at least 2-3 weeks further. A second grow space will be required to pull off monster cropping. Although a CFL and micro tent is not much of an investment and won’t take up a lot of space.

Accidental Re-Vegging

Light pollution can cause photoperiod cannabis to re-veg or worse, turn hermie. This can be a real problem for urban outdoor growers as street lights can easily cause this to occur after sundown. Similarly, indoor growers can run afoul of this unintended re-vegging if the grow space is not light tight. That means no light leaks and no outside source can penetrate.

Another cause of accidental re-vegging can be a faulty timer plug. Check the settings regularly to make sure the correct hours are set. Then physically inspect the grow room routinely to make sure again.

How To Monster Crop

STEP 1: Select your best female plant at about 28 days into the 12/12 bloom cycle.

STEP 2: Take cuttings as outlined earlier in the text. Start with the bottom branches and work up without butchering the donor mother.

STEP 3: Re-veg clones under your preferred light cycle (18/6, 20/4, 24/0) until they branch profusely and leaf growth begins to return to normal. In about 30 days from taking the cuttings, you should have some monsters on your hands.

Is Monster Cropping Worth It?

Yes absolutely, provided you’ve got the grow skills. Monster cropping is not exclusive to grand master growers. But you do need at least an intermediate level of experience to get the most from the technique. As a standalone method, monster cropping is a good two-for-one combo, facilitating another run of your favourite female plant. And, by increasing the branching, the monster cropped clone usually benefits from a boost in yield. Not to mention more branches to clone from next time.

If you have the green fingers to keep pruning and training, monster cropping can take your yield into unchartered, scale-tipping territory again and again.

Monster cropping is not just a high yield cultivation method, it’s also a great way to preserve your best female. Check this out, home growers!
