Why “Monstercrop” a Marijuana Plant?

When it comes to monstercropping cannabis plants, the main idea is to put a flowering plant back into the vegetative stage, either by growing a plant out again after harvest, or taking a clone from a flowering marijuana plant.

As a side effect of the re-vegging process, cannabis plants respond with odd growth patterns, which a grower can sometimes take advantage of to grow a more desirable plant.

Monstercropping initiates a bushy growth response that you can use to your advantage, while potentially allowing you to get a second harvest from the same plant!

The benefits can include increasing yields from a plant, reducing the time needed in the vegetative stage for your next harvest, and potentially protecting important genes of a plant that produced particularly well.

It can get kind of confusing because people often use the terms “re-vegging” and “monstercropping” interchangeably, but they’re a bit different. Re-vegging is the act of a flowering plant going back into the vegetative stage (usually on accident) while the term monstercropping refers specifically to the technique of re-vegging a flowering plant on purpose.

It’s also important to note that monstercropping is different from supercropping, which is a completely unrelated technique that just happens to have a similar name. Supercropping has to do with bending the stems in a specific way to increase canopy control as well as yields. I’ve come to realize over the years that the terms used by cannabis growers don’t necessarily make the most technical sense! Teach me about supercropping cannabis.

Every individual plant responds differently to being re-vegged, even of the same strain, so it can be a little hard to predict exactly what to expect.

It Can Be a Little Hard to Know Exactly What to Expect Since Each Plant is Different, But Re-Vegging Plants Usually Start Growing Round Leaves

Every strain expresses re-vegging a little differently!

The longer the plant spends in the flowering stage, the more dramatic the effects from a reveg, and the longer it takes the plant to completely re-vegetate and start growing normally again.

As the plant transitions back to the vegetative stage, it will start growing standard leaves, and after about 2-4 weeks, most plants will be growing in a traditional way. The effects of monstercropping only last a few weeks for most plants!

Monstercropping can be a great choice for outdoors in temperate climates because it allows an additional outdoor harvest by planting in the winter, harvesting in the spring, then revegging and doing a second harvest off the same plant in the fall.

Monstercropping Can Also Be Used to Preserve Good Genes

If you are very pleased with the results of a specific cannabis plant, you may want to take clones even though the plant is no longer in the vegetative stage!

This grower took clones of all plants just before harvest, and after drying/curing chose to only keep the monstercropped clone from the plant that made these buds. Monstercropping gives the grower a way to preserve genetics that turn out better than expected! Don’t lose important plant cultivars!

Sometimes re-vegging happens by accident, for example if there’s a light leak (though an industrious grower could try to use the opportunity to try their hand at monstercropping)! That being said, monstercropping is far more effective when you plan for it.

Strain and Plant Choice for Monstercropping

I highly recommend only attempting to monstercrop a plant that has grown fast and vigorously in the both the vegetative stage and the early part of the flowering stage. If at all possible, you want a plant that is able to quickly grow lots of new stems and bud sites, so you can get back to flowering and harvest again as soon as possible.

Plants that stay short and grow slowly can take a very long time to re-veg and “get going” again. In that case, you would be better off starting fresh with a seed, which grows vigorously from the beginning as long as it’s fresh and germinated properly, even strains that tend to stay short.

Very Short or Slow-Growing Marijuana Plants May React Poorly to Monstercropping. Try to Choose Only the Best Plants!

If you’ve got a limited space or height, you may not want to monstercrop a particularly tall marijuana strain, as the second version of the plant may end up being bigger than the first!

Lastly, never try to monstercrop an auto-flowering strain, as they are basically unaffected by light schedules. This means they typically can’t be forced to re-veg.

How to Use Monstercropping to Increase Yields Indoors

If you plan on monstercropping an indoor plant, or if it happens by accident, how do you take advantage of the strange re-veg growth? If you are going to re-harvest a plant, what’s the best way to do that?

Tips for Successful Monstercropping Indoors

  1. Choose a medium size strain – Short strains tend to grow on the slower side and may not grow fast enough to really take advantage of monstercropping. On the other hand, tall strains tend to grow fast and stretchy, which can make it far too easy to overgrow your space during the second round). Learn more about cannabis strain research.
  2. Only monstercrop the best cannabis plants. For the best results, make sure to only monstercrop plants that grew quickly and healthfully throughout their life up until week 6 of the flowering stage. Starting with a few extra plants the first time will give you the ability to choose the best instead of settling for whatever you get.
  3. Make sure to train plants to stay flat and wide for the best results. Regular training rules apply, you just have a bushier and faster growing plant!
  4. Leave a solid and wide base even while harvesting, as you will be growing your plant off of the “skeleton” you leave behind.

Although this grower got good yields, and the picture shows the monstercropping structure perfectly, the yields would have been even better if the grower had lollipopped less (so that buds go down further on the stems) and had defoliated the top colas so that all the buds are getting access to direct light. Training technique can make a huge difference no matter how you grow!

How to Re-Veg a Flowering Clone…

  1. Choose a cannabis plant that has grown well and is overall performing above average. These are the genes you want! If you are impressed with the bud quality, that’s another great reason to monstercrop a specific plant even if it’s not necessarily growing the best. Some growers will take clones from all their flowering plants (with labels to know which is which!) soon before harvest and start monstercropping them. By the time the clones are a few weeks old, you’ll have been able to test your buds from harvest and see if there were any plants that just produced star quality bud. At that point, you can toss all the clones that came from average plants, and keep any winners to grow again. Once the plant starts vegetating again, it will be much easier/faster to take more clones.
  2. Make sure to give your new flowering clone the best care possible, and remember it may take a few days longer than a normal clone for your cutting to root and start growing again.
  3. Keep the clone on a vegetative time schedule (18-24 hours of light/day) and start giving it vegetative nutrients.
  4. The clone will start growing very oddly, with round leaves and often with many stems, creating tons of bud sites in a very short amount of time. The odd growth lasts 3-4 weeks on average, though it will take shorter if plant wasn’t flowering long, or possibly longer if the clone was taken just before harvest time.
  5. Don’t skip on plant training! During the vegetative stage, it’s very important to make sure the plant is trained to stay short and flat, so you can take advantage of all those bud sites!
  6. When the plant is about half the final desired height, switch to a 12/12 light schedule and continue keeping plant flat during the first 6 or so weeks of the flowering stage, until the plant stops growing new stems and leaves altogether.
  7. Harvest as normal and enjoy your monstercropped buds!

Example of a Recovering Clone After Being Monstercropped

In this instance, the clone seemed to get back to the vegetative stage more quickly than most. This clone was taken from a flowering cannabis plant, notice the strange rounded leaves

Here’s the same plant 2 days later. It continues to grow new leaves with round edges and long stems while the plant is re-vegging.

Here’s that plant about a week later – at this point it’s already growing (mostly) normal leaves

Only 1 month after the first picture, the plant has grown far bigger and faster than a similarly sized seedling would have been able to grow in that time.

That plant at harvest! The grower said that they were extremely happy with the results of the monstercrop process and would do it again!

How to Re-Harvest the Same Plant Twice…

  1. Train your plant with multiple colas and a wide base during the initial grow. This will ensure you have good plant structure the second time around.
  2. When you harvest the plant, you should remove all the buds but you must make sure to leave several stems and healthy, green leaves remaining. Consider that all new growth will originate from this, so consider that when making cuts to your plant during harvest. You want to leave enough behind to make a great base. If you leave any buds behind while the plant is re-vegging, they’ll eventually start to wither and die.
  3. Put the plant back into a vegetative time schedule (more than 18 hours of light/day) and start giving it vegetative nutrients.
  4. The plant will start growing crazily, with round leaves and often with many stems, creating tons of bud sites in a very short amount of time. The odd growth lasts 3-4 weeks on average, though it will take shorter if plant wasn’t flowering long, or possibly longer if the clone was taken just before harvest time.
  5. Don’t skip on plant training! In the vegetative stage, it’s very important to make sure the plant stays short and flat, so you can take advantage of all those bud sites!
  6. When the plant is about half the final desired height, switch to a 12/12 light schedule and continue keeping plant flat during the first 6 or so weeks of the flowering stage, until the plant stops growing new stems and leaves altogether.
  7. Harvest as normal and enjoy your second set of buds!
  8. What about a third harvest? it’s generally not recommended to harvest a third time, as yields often suffer, and plant just doesn’t re-veg as easily or grow as vibrantly the third time around. But that doesn’t mean it can’t be done!

Note: Results can vary depending on the strain. Some strains will produce the same or more for their second harvest, while some strains don’t respond as well and may end up with lower yields.

This plant was just harvested, and the grower plans to allow it to re-veg by putting it under a 24 hours light schedule. In order to help the plant re-vegetate more quickly, it may have helped to leaves a few more leaves, as opposed to leaving buds, but this will work! The grower left a good “spread” at the base to help the plant grow wide and flat, almost like a manifold.

Three days later. Notice you have new leaves but the buds are already dying. When the plant re-vegs it “gives up” on the buds and they wither, so it’s better off to harvest them all, and focus on leaving as many leaves as possible!

Example of Flowering Plant Being Re-Vegged on Purpose (“Monstercropped”)

The grower liked the results from the “mother” plant and wanted to grow the same cultivar out again.

Here’s the plant not-too-long after harvest.

Look how the monstercropped plant grows naturally in a very bushy way, without needing training by the grower.

This is that plant less than a month later, just before switching to flowering. This particular plant naturally grew nearly 80 tops! The entire process took 1 month and 19 days to reach this point, which is bigger with more colas than a plant grown from seed would have been able to grow in that time.

Monstercropping, can be a really fun experiment, but remember that it can be a little unpredictable so it’s always recommended to grow backup plants at the same time, at least until you get more experience!

Monstercropping Outdoors in Temperate Climates for Multiple Harvests/Year

Monstercropping can be great for outdoor growers with warm temperatures all year long, because if you time it right, you can harvest twice/year. You’re taking advantage of the fact that plants will start flowering with long nights, and start vegetating with short nights.

  1. The grower plants their seeds in winter, which causes the plant to start flowering almost immediately since the nights are long in winter
  2. (Optional) You can keep plants in veg longer by making sure they get access to a small amount of light at night, so they never spend more than 12 hours in darkness, but you don’t want them to spend too much time in the vegetative stage because they should be ready to harvest by late Spring, just as days are getting long enough to turn the plant back into the vegetative stage.
  3. The grower harvests the buds at that point, leaving a well-developed root system and hardy plant base right as the “real” growing season begins.
  4. Grows plant out as normal the second time.

After the first harvest, make sure to leave a wide base with plenty of leaves if possible, so that your plant can start growing bigger and wider more quickly! A head start in spring means you can grow bigger plants by fall!

This can give your plant a head start, so not only do you get that first extra harvest, you may get more buds in the autumn because the plants could be bigger. For those who live in climates where the temperatures never go down to freezing, this can be a good way to get multiple harvests!

Strain Choice for Outdoor Monstercropping

For outdoor cannabis monstercropping, choose a strain that needs a relatively short time in the flowering stage, for example one that needs less than 8-10 weeks in the flowering stage before being ready to harvest.

This ensures your buds will be ready to harvest in time for late Spring, and short-flowering strains tend to be less sensitive to the fact that the day lengths are increasing (which can cause some long-flowering, Haze or Sativa plants to re-veg, even if the days are still short, because they can “sense” the days are getting longer)

Avoid Re-Vegging a Plant by Mistake; the Results Are Unpredictable Without Preparation!

This plant was almost done flowering, but then started getting light leaks at night. In this case the grower didn’t want the plant to re-veg. It’s recommended they either harvest buds immediately, or cut off all the new growth and make sure the plant is getting 12+ hours of uninterrupted dark every night. It’s possible the plant will get back on track but if you notice the buds appearing to wither, harvest immediately!

Another example of an accidental re-veg. In this case the plant was accidentally getting light at night, which caused it to revert back from flowering. In general, you want to avoid re-vegging by accident since you don’t get a lot of benefit from growth like this.

Now you’ve learned about how to use the monstercropping technique for indoor and outdoor marijuana grows! Do you want to learn even more about re-vegging cannabis plants?

One thing to keep in mind with monstercropping is it can be a little hard to know exactly what to expect, so make sure to remember that it’s an experiment and try to enjoy the twists and turns 🙂

Gigantic Marijuana Plants

Cannabis crops are some of the most versatile crops on the planet, capable of adapting to almost any growers needs thanks to the amazing variation in how long some strains take to grow versus others. You can find spectacular autoflowering strains that are ready to cut in just about two months of cultivation, and then you can also find seasonal strains that need certain photoperiods (periods of light and darkness) to grow and flower. Today we’re going to talk about some tips and tricks to grow gigantic marijuana plants; to do this they’ll need a longer growth period and a whole lot of care, but you’ll be rewarded with the biggest specimens that you have ever seen.

Many growers have already seen astonishing images in which American growers are standing beside incredible 4 or 5 meter tall marijuana trees with an enormously dense branch structure that end up looking like big green balls. This phenomenon is quite typical in Humboldt’s seed catalogue and other American seed banks, as well as professional growers books and of course thousands of images and videos online.

Choose a good strain

Choosing a strain with a decent growth level is essential because your plants entire structure will depend on this specific characteristic. Sativa strains tend to have a much larger growth as well as a larger distance between nodes and a thinner, taller structure. Indicas, however, grow into more manageable plants with shorter distances between nodes, more branches and a stronger central stem.

Indica and sativa hybrids obviously have characteristics from both genotypes, although depending on the strains used to create the hybrid and the percentage of indica vs sativa, they’re more likely to have certain characteristics. Generally, the biggest specimens will have a sativa percentage of over 60%; if the plant is indica-dominant then the specimens will be more compact but with a larger branch structure.

Make sure they get a good growth period

Growth timing is definitely a key element when trying to grow large plants due to the fact that once your plants move on to the flowering stage, they tend to get a lot bigger. This means that the bigger your plant grows during its growth stage, then the more they will develop during the flowering stage.

For outdoor crops, growers have to depend on the seasons and the climate for their plants to switch periods, whereas indoors the grower decides when to change the light period, allowing him or her to choose how big their plants should grow. This means that indoor growers can play around with the number of plants and the timing of their crops; with a shorter growth period you can have more plants. This is how SoG systems were born; cuttings don’t need a growth phase and seeds only need two growth weeks.

There are also growers that like to fill their crop area with just one plant, giving it an enormous growth period as well as a large flowerpot; this makes for plants that would leave outdoor growers astonished. Some seed banks keep mother plants for over 10 years, so we know that you can give your plants all the growth time you want and rest assured that they won’t die (if you take care of them properly).

So, now that you know that you can grow plants indoors for as long as you want, and that outdoors marijuana plants grow a larger branch structure, the question is: What would happen if you let your plants have a long growth period and then took them outside to flower?

When you grow your plants indoors and then take them outdoors they go from getting 18h of light a day to getting a lot less, so they immediately begin flowering. If it’s still growth season your plants will begin budding but then they’ll revegetate, losing potency in the process which is something you want to avoid, especially with a crop like this that takes a lot more work.

However, if you take your plant outdoors to flower when the sun begins to set earlier, your plants will begin flowering normally and should be ready around the same time they would be ready if you had planted them outside from the beginning. The obvious difference is that these plants will be much larger and have a much higher yield; by using this method you can get plants that are over 4m tall.

Increase the number of branches through pruning

If you use the previous method it’s not hard to get gigantic plants, but large plants don’t necessarily have a lot of branches. If you’re looking to increase the number of branches on your plants then you’ll need to consider pruning them.

It’s actually quite common for indoor growers to prune their plants every now and then when they’re employing a long growth period. If done properly without stressing your plants too much, then your plants should grow various new branches per pruning. All you’ll need to do is use a revitalizer on your plants to reduce stress and a couple of weeks after pruning more branches will have grown. If you’re thinking of using a growth period of a few months then you’ll have enough time to repeat this process a good few times. Once they begin flowering the amount of branches will obviously be higher, making your plants incredibly leafy and bushy.

Stake or string your plants to increase strength

Staking plants is essential if you want them to develop correctly and constantly, so you’ll need to start doing it during their first few days. You’ll need to start by staking the trunk and then wiring the branches that grow, which will give a higher yield thanks to being held up.

When your plants have reached the production levels that we were talking about before, the stakes or string you’re using might not be strong enough to put up with the weight of the branches and buds; one of the most recommended systems is by using metal meshes. By doing this you can hold up each branch individually and with less stress on the mesh due to the fact that the weight of the plant will be evenly distributed. It’s also pretty easy to set up, all you have to do is extend the mesh over your plant, placing each branch in a hole making sure that light can still access all of them.

So, now you know that if you want to get monstrously huge plants you have to consider the strain, give them a much longer growth period, prune selectively, and make sure that it can deal with the weight of all of those amazing buds. If you follow all of these tips you’re guaranteed to produce enough per crop to keep you going in between seasons. We recommend using organic fertilizers to increase flavor and cannabinoid levels in your plants, so that way your gigantic marijuana plants will have an extremely high production rate as well as powerful and flavorful buds.

Learn how to grow gigantic marijuana plants, you'll get an enormous yield without using any chemical fertilizers that could alter the final product.
