Monster Cropping Cannabis Guide


Monster cropping is a relatively new method to increase yields. This technique involves taking clones from a flowering plant and revegging them, when you reveg a cannabis plant she will develop an unusual growth, becoming extremely bushy, with lots of side branches and flowering sites.

1. What is monster cropping?

Monster cropping is quite new for cannabis growers. This method consists of taking clones from a female plant that’s 2-4 weeks into the flowering stage and placing it in a vegetative light cycle. By doing so we are disrupting a plant’s growth and she will start to develop unusually bushy.

When a cannabis plant is revegged it will develop an unusual growing pattern, this unusual growth can consist of more flowering sites, side branches and leaves, this is used by growers to increase yields or better prepare plants for training techniques such as Scrog or lollipopping.

Have in mind that monster cropping it’s not for autoflowering cannabis plants. This method is to be used strictly with photoperiodic cannabis and if done correctly, you can not only increase yields but also reduce the time needed in the vegetative stage of your next cycle and it’s a great way to keep a specific genetic in your grow room for as long as you want.

2. Does monster cropping work and how long it takes?

Monster cropping indeed works, and works like a charm, although there’s no way to say exactly, have in mind that plants have different growing rates, just to give you an example, if you vegetate your plant for 4 weeks, you’ll have to wait those 4 weeks plus 2-3 weeks of flowering and add 2-3 weeks for your clones to root properly.


Monster cropping: revegetated cannabis plants developing a unique growing pattern

Revegetated cannabis plants will develop a unique growing pattern.

Even though it can take quite a lot of time you will be satisfied with the results, you’ll see it’s worth it to wait a couple of weeks more to immensely increase your yields.

3. Pros of monster cropping

  • Monster Cropping improves yields

Revegetated plants will grow more, bushier and with more side branches, this will result in more flowering sites and consequently more buds.

  • Continuous harvests without having to keep mother plants

Because you are taking the clones from flowering plants, there’s no need to keep a mother plant in the vegetative stage to take clones from, you can flower all your plants and decide if you want to take clones in the first weeks of flowering.

  •  Great way to prepare plants for other training techniques

It is recommended to combine monster cropping with plant training techniques such as Scrog, tying down branches, or even topping or fimming, this will allow the buds to develop properly and grow super dense.

4. Cons of monster cropping

  • Monster cropping takes time and work

Flowering a plant, taking clones, and waiting for them to revegetate can take quite a lot of time, so it’s not recommended if you want a fast harvest.

  • Can’t be used with autoflowers

Because autoflowers don’t depend on a light cycle, they cannot be revegged, so this technique doesn’t work with autoflowering strains.

  • Not all clones will live

Flowering clones have a low success rate when compared to clones from a vegetative plant so it is expected some won’t root and die. It is recommended to take extra clones in the case some don’t survive.

Note: We don’t recommend monster cropping smaller strains, it is better to use this technique with strains that grow tall, fast and with a lot of side branches. Smaller plants or strains that take too long to grow can take more time to reveg than simply germinating a seed.

4. How to monster crop: step-by-step guide

Step 1: Choose the cuttings

You can take flowering clones in between the 2-4 week of flowering, even though this won’t affect the result that much, we recommend taking the clones in the 3 week of flowering.


Monster cropping: how to cut clones 

When taking clones, it is better to take them from the lower branches because they tend to root faster.

When choosing the branches to cut, it is better to go for the lower branches because they root faster than the ones from the top, when taking a clone you should make a diagonal cut (this will provide a bigger surface to absorb nutrients and water) around 0,5cm below the node.

Remember that flowering clones have a low success rate so you should take some extra cuttings, if you want 3 clones, you should take around 5-6 just to make sure.

Step 2: Wait for the clones to root

After taking the clones quickly place them in water, you can also apply a rooting hormone to increase the chances your clone will survive, remember that if air goes in the vascular system it can cause an embolism and die, so you should apply the rooting hormone and quickly place them in water.

After taking the clones, you can apply a rooting hormone and quickly place it in water.

You should leave the clones in water for some time and only transplant them after you see root development.

Step 3: Revegetate the clones

When the plants are ready to be transplanted you have to provide a vegetative light cycle (18/6, 20/4), there’s no need to provide too much light (at least for now) because clones don’t need a lot to survive, just make sure you don’t stress your plant because this process is a bit stressing to the plant, so if you stress them more they will stop growing.


Monster cropping: light cycle for clones

Clones need a 18/6 light cycle to start growing properly.

Note: If you want to save up a little bit of money, instead of using the same light fixtures you use to grow and flower cannabis, you can use CFLs because clones don't need too much light to grow, just make sure you change it after they've grown a bit.

5. Combining monster cropping with other techniques

As said above, when revegetating plants, they will develop an unusual growth pattern with lots of leaves, branches and flowering sites, this is extremely helpful when you want to make the most out of each plant or facilitate the process of training your plant to fill a Scrog trellis or in other training techniques.

After monster cropping, when your plant has reached a good size, you can start tying the branches. Training it under a trellis net or even top it to achieve the desired result, because there’s more plant to work with, it will be easier and you will be able to harvest lots of buds from just one plant.

6. In conclusion

Even though it takes time and can be frustrating when your clones die, this is a great way to increase yields while not having to spend a lot of money with seeds. 

We recommend this technique to more experienced growers but this doesn’t mean you shouldn't adventure into monster cropping. If you're a new grower, just make sure you have other plants growing along so you don’t risk your harvest completely. Take the appropriate care and you’ll be harvesting lots of buds in no time.
