CANNAZYM: When To Use It, What It Does & Does It Help To Treat and Prevent Root Rot

What does CANNAZYM Do and how to use it

Hello there dear gardeners from all over the UK! We have written a few guides on CANNA and their products, however, it looks like there are some questions that need a bit more digging into. Today we will talk about what does CANNAZYM do when to use it, how to use it, can you use it in soil/hydroponics/coco, and does it help you treat and prevent root rot

Make sure to read the full guide to get the full scoop. 


CANNAZYM is an enzyme product manufactured by CANNA – the infamous Dutch company that produces environmentally-friendly fertilisers and growing mediums.

What are enzymes?” you might ask. 

And because we believe that in order to be an amazing gardener you absolutely need to know exactly what’s happening in your plants and why, we will get down to the nitty-gritty of enzymes. Bear with us, as we have tried to keep it concise and easy to digest. 

Countless biochemical reactions take place within living organisms all the time. While the term “metabolism” is commonly known as the process of breaking down food and its transformation into energy, metabolism can also be explained as the sum of all the physical and biochemical reactions in an organism

And enzymes are the biological molecules (typically proteins) that make these biochemical reactions happen. Enzymes are vital for the life of both humans, animals and plants because most of the biochemical reactions in organisms need help in order to take place.

Some enzymes help catabolic reactions to take place. These reactions are exothermic (heat-releasing) as they break down molecules into smaller pieces and release energy. These smaller units are now more easily absorbed by the human body or the plant. 

Other enzymes help anabolic reactions to take place. These are endothermic (heat-absorbing) chemical reactions where two molecules bind together to produce a new, bigger molecule and absorb energy.

Think of enzymes as tiny biological catalysts that have a very important job (and do it extremely well). Without enzymes, a typical biochemical reaction might take days, weeks, years or centuries to occur. All forms of life live by enzymes and produce enzymes. And there are many different types of enzymes, since they are substrate-specific (each enzyme affects only a specific substance/molecule).  

We hope you now understand exactly how important enzymes are for the growth and development of living organisms like your plants.

One last thing to keep in mind for later. In order for enzymes to work, they require specific conditions – like temperature and pH. 

Ok so let’s get back to the star of this article – CANNAZYM.

So What Does CANNAZYM Do & What Is CANNAZYM Used for?

If you have carefully read the previous section of this article, you now know two very important things. First, CANNAZYM is an enzyme product. Second, enzymes are absolutely essential for all life forms – such as humans, plants, animals, fungi, bateria, etc

Now let’s talk about what makes the enzymes in CANNAZYM so beneficial for plants and how exactly they work

CANNA was founded in the early 90s and is a company with decades of experience in research and development of nutrients and growing mediums. This means that their team of highly trained specialists has spent years researching and testing what are the enzymes that specifically target the food source and cause of root binding, dead root material, and old cast off. These enzymes are now part of the CANNAZYM formula. And you can be confident they work as the company promises since the CANNAZYM formula hasn’t (officially) been changed in the past 20 years

Excited to find out more? We will now go through the details of exactly what CANNAZYM does and what it is used for.

Root rot is probably the most common issue urging gardeners to start feeding their plants an enzyme product like CANNAZYM.  

If you notice early signs of root rot, CANNAZYM can help! Its enzymes will work quickly to break down any dead and decaying root material, thus reducing the risk of disease and the development of harmful pathogens. 

CANNAZYM Turns Dead Roots Into New Food For Your Plants  

Advanced gardeners who know the power and importance of enzymes, use enzyme products throughout the whole growth cycle. Because products like CANNAZYM should not be viewed and used as simply “the last resort of fixing plant root issues”.  

The enzymes in CANNAZYM significantly speed up the process of turning dead root material into sugars and minerals. Which means that your plants can now use up this “new” valuable source of nutrients exactly when and where they are needed.

CANNAZYM Improves Nutrients Uptake

To make it even better, CANNAZYM’s formula also includes Desert plant extract and vitamins. What do they do? They help improve the water and nutrient uptake of roots and stimulate the crop’s natural defence mechanisms.

CANNAZYM Stimulates New Roots Formation

Yes! CANNAZYM does not only help you get rid of dead roots by turning them into usable nutrients for your plants. It also stimulates the formation of new healthy roots. And you know that one of the keys of a healthy, thriving plant is a big, beautiful, healthy root system. 

CANNAZYM And Your Substrate 

By removing dead roots, vital space for air pockets is kept free. This ensures high oxygen levels in the substrate, optimal environment, improved beneficial bacteria and root efficiency. This new space also helps avoid pot binding. 

CANNAZYM For Reusing Grow Media 

CANNAZYM is also often used when gardeners want to reuse growing media, especially coco coir

Using this enzyme product throughout the grow cycle and soaking your grow media with it afterwards, will help you get rid of any decaying roots left from the previous crop. That way you enrich your soil with advantageous nutrients for your next crop cycle and improve the substrate’s aeration. 

Well.. We just listed 6 different ways the enzymes in CANNAZYM help your plants have a healthier, more vigorous and satisfying growth and development. We even talked about the fundamentals of biochemical reactions and enzymes in living organisms. If you are ready to purchase this fantastic product, head over to our shopping section and order your CANNAZYM today. We deliver right to your door, all over the UK.

Video – What Does Cannazym Do?

Want to see CANNAZYM’s enzymes in action? Check out this wonderful short video, where the processes of breaking down dead root material, activation of beneficial organism, and substrate aeration have been visualised:

In the video, CANNA explains that the root system starts producing new root hairs once the substrate dries out, so that the plant can absorb more water and nutrients.

And once you water your plants, the root system will not need as many root hairs as it has produced, which is why the oldest ones will die out and be shed.

But these dead roots turn into a good environment for the development of molds, fungi and harmful bacteria. You wouldn’t want that would you

CANNA then goes a bit more into detail about two of the enzymes found in CANNAZYM – Pectinase and Endocellulase. 

Pectinase enables the breakdown of pectin. Pectin is a type of starch, called a heteropolysaccharide. It occurs naturally in plants’ cell walls and gives them structure.

Endocellulase breaks down cellulose after the pectin has been broken down. This enables the content of the cells (which were surrounded by cellulose) to be released. The microorganisms in the substrate then absorb these nutrients and convert them into minerals and sugars. These minerals and sugars will now be absorbed by the new root hairs.

To put it simply, these enzymes help turn dead root material into food for new roots

And how does all of this increase aeration in the soil? 

Once the dead root hairs have been broken down, an empty air pocket remains in their place. This helps maintain the condition of the substrate by increasing air circulation through the substrate and prevents pot binding. This way your plants’ roots have room to “breathe” properly, take in water and nutrients.

Sounds pretty neat doesn’t it? 

A CANNAZYM Experiment 

If you have been looking into the topic of what does CANNAZYM do and how to use it, you might have already stumbled upon CANNA’s (rather unsatisfying)* two-step experiment. If you haven’t watched it yet, let us save you the time of searching for it by pasting the link here:

*If you watched the whole 10 minute video, you probably understand what we mean. We loved the test and its results, but wouldn’t it have been even cooler and a lot more impressive if the test was done with actual plant roots and substrate (instead of the paper and apple sauce they used in their video)?

Some More CANNAZYM Questions Answered

If you have reached this part of our CANNAZYM guide, you are either really enjoying our writing style… or you still have some unanswered questions. In this section we will go through some of the most common CANNAZYM questions and their answers. 

Can You Use CANNAZYM In Soil, Coco and Hydroponics?

Yes! CANNAZYM is suitable for use in all growing mediums. 

What Other Additives To Use Alongside CANNAZYM? 

For maximized performance, we recommend to use CANNAZYM along with the rest of CANNA’s additives:
RHIZOTONIC – a root stimulator that helps with root development, increases plants’ strength and disease resistance. 
PK 13/14 – a PK booster that ensures stronger cell formation and the production of enough sugars in the flowering stage. Discover more about PK 13/14 here.
CANNABOOST – a flower booster that improves the health and metabolism rate of short-cycle plants.

What Are Some CANNAZYM Alternatives? 

Almost all nutrient companies manufacture their own enzyme products, so there are a lot of available alternatives. Hygrozyme, Advanced Nutrients’ Sensizym, or the fully organic energy booster Biobizz Bio-Heaven (Bio-Heaven does not contain enzymes, but stimulates enzymatic activity in an all-natural way) are some of them. 

Should I Shake My CANNAZYM Bottle Before Using It? 

You may notice that when you leave your CANNAZYM bottle sitting on the shelf, it will start slightly separating its constituents. But don’t worry! It will get back to suspension very easily once you shake the bottle. 
So yes, always shake the bottle before using it. 

Does The Colour Of My CANNAZYM Indicate The Age Of The Product? 

CANNA states that the colour does not indicate the age of the product. You are not likely to see any significant changes in the colour of CANNAZYM.
