Canna is one of the most popular fertilizers and substrate manufacturers all over the world, since its foundation in the 1990s, the company has been putting several products on the market designed for all plants, including cannabis, with excellent results. This Dutch company has been known for lab testing all their products and proving their quality, making their top-quality products available all over the world, including Europe, North America, the Middle East, and Africa. So if you want to know how to better use them or want more information before using them on your grow cycle, here you will learn a bit more about their products, how to better use them in every grow setup, and the best feeding schedule for using Canna products with autoflowers.

1. Inorganic Fertilizers

Canna offers a wide range of inorganic fertilizers made with high-grade nutrients and chelates which results in a better quality product that makes the nutrients readily available for your plant to absorb. So if you prefer inorganic over organic fertilizers, read along for more information about their products and the best feeding schedule for hydro, coco, and soil! Of course, inorganic and organic fertilisers have their own unique advantages. Inorganic fertilisers shine for numerous reasons and come in extremely handy in certain situations. First and foremost, these inputs mean that growers don’t have to spend anywhere near as much time building up a healthy soil and amending it with a long list of additives, such as compost, organic matter, beneficial microorganisms (such as bacteria and fungi), and a long list of dry amendments.

This is because inorganic fertilisers work right away. They offer nutrients in their most basic ionic form, meaning plants can take them up right away. Many growers that opt for these products are able to quickly put together simple growing mediums consisting of coco coir, peat, and perlite/vermiculite. Inorganic fertilisers also allow growers to be extremely accurate with their dosing regimens. As opposed to throwing lots of different organic components into a pot and hoping for the best, these growers have the luxury of data; they’re aware of the exact amount of each nutrient within a feeding solution every time they apply nutrients to the soil. Furthermore, these types of fertilisers are very helpful during times of deficiencies. Because they act so quickly, they’re able to rapidly remedy curling and yellowing leaves and stunted growth.

However, just because you don’t have to pay as much attention to your soil doesn’t mean you should neglect it entirely. Selecting the right growing medium can help you make the most out of your inorganic fertilisers. Including good amounts of clay and organic matter in your containers or raised beds will help to prevent them from leaching right out. Why? Because both of these substances feature a net negative charge, and many plant nutrients are cations with a positive charge. This means that soils higher in clay and organic matter are able to hold onto these nutrients, meaning these growing mediums have a superior cation exchange capacity.

Canna Terra

Canna Terra is a product line specially designed for growing in soil, either outdoors or indoors. The special nutrient mix has been developed to provide great results for growers with little experience to more experienced growers.

2. Additives

As you may have seen in the tables, you will have to use some additives for the best result possible. These additives improve plant health and yields, and are used in all of the feeding schedules above so here’s a bit of information for you to know why you should use them.


Cannazym is one of the top-selling additives on the entire market, and it’s easy to see why. Not only is it produced by CANNA, one of the most trusted cannabis cultivation brands the world over, but it also just does exactly what it says on the box. Cannazym contains enzymes designed to stimulate root growth, boosting plant health even more; This product prevents harmful bacteria and fungi from attacking your plant while also removing dead roots, keeping vital root space free and full of oxygen, thus improving overall root health.


Nitrogen (N)Phosphorus (P)Potassium (K)


The beneficial enzymes in CANNAZYM convert dead root growth into minerals and sugars, transforming them into bioavailable nutrients that help feed the plant. Dead roots are the perfect breeding ground for detrimental mold and bacteria, so by speeding up the decomposition process the risk decreased. The mix of more than 12 different enzymes and vitamins with extracts from desert plants helps boost the plant’s natural defenses and hormone production capabilities. CANNAZYM promotes the accelerated growth of new roots and helps ward off many harmful bacteria and mold. If you are looking to reuse your growing medium (like with no-till farming) CANNAZYM is an indispensable tool.

How and When to Use

  • Make sure you remeber to shake the bottle up well before every single use.
  • Add 25ml of CANNAZYM to 10 liters of filtered water.
  • Can be used daily or weekly, throughout the entire grow cycle.
  • Can be stored in a cool, dry, dark spot for up to 4 days.
  • Do not mix with hydrogen peroxide. 


Rhizotonic is a strong root stimulant that aids in nutrient absorption and helps improve root development; After the first few uses, you’ll see extraordinary root growth while improving your plant’s resistance against diseases and keeping them healthy. This algae-based vegetative growth simulator contains vitamins such as B1&B2 which boost the plant’s natural ability to produce hormones and root growth. Perfect for use with clones, cutting, and transplants. It also helps speed up the germination process. Simply dilute 40ml of RHIZOTONIC in 10 liters of water and soak your seed overnight in the solution. This allows the seed to burst and germinate a lot faster than if just soaked in water.


Nitrogen (N)Phosphorus (P)Potassium (K)

How and When to Use

RHIZOTONIC can be used with any type of growing medium and style, and can be used from seed to harvest (always remember to flush before harvest). It can be applied directly to the leaves and a foliar spray, as a pretreatment for all substrate types, or in with the nutrient solution that you feed your plants.

  • Remember to shake the solution well before use.
  • Mix with fresh, filtered water at a rate of 1:250 - eg 40mls to 10 liters.
  • Can be used as a foliar spray up to six times daily. 
  • Can be added to the daily feed every day.

CannaBoost Accelerator

Boost Accelerator is a flowering stimulant that allows you to make the most out of each plant, providing everything your plants need for bigger and denser buds, and an overall bigger yield.


Canna feeding chart: cannaboost accelerator

CannaBoost Accelerator provides everything for bigger and denser buds.

When used properly, this product will improve basic processes such as photosynthesis, resulting in a shorter internodal space and more compact buds. It does this by boosting the metabolism of your plant. When combined with PK13/14 you can achieve unseen flowering results, no matter which growing system you are using. CANNABOOST offers a key few benefits, including:

  • Improved yield size - This additive stimulates heavier, denser, more compact bud growth which increases the yield weight. 
  • Improved flower ripening - Not only are the yield sizes increased, but the final product is of much better quality. Terpene and trichome production are both boosted, with the terpene profile allowed to reach its full potential thanks to the sugar production boost from the increase in photosynthesis
  • Strengthened immune system - The enhanced energy regulation of the plant means that there is more energy to resist diseases, fungus, mold, and pests. 

How and When to Use

  • CANNABOOST works best when using a dilution of 1:500 (20 ml per 10 liters of water) from the moment that flowers start to form. This can be doubled an or extra flowering boost.
  • The solution will store fine for 4 days in a cool, dry, dark area. 
  • Can be applied as a foliar spray or added to the nutrient feed solution.

PK 13/14

PK 13/14 is a flowering booster designed to fatten up buds, by using it in combination with other products your plant will develop huge amounts of resin and very dense buds, thus improving yields; Everything you want your harvest to be, just make sure you don’t overuse it to avoid nutrient deficiencies!


Nitrogen (N)Phosphorus (P)Potassium (K)


As the name might suggest, this is an additive that boosts Phosphorous (P) and Potassium (K), both of which play a major role in the flowering of cannabis. Phosphorous (P) plays an important role in energy transfer and the metabolism of cannabis and is vital for the flowering stage if you want to get the fattest, juiciest bids possible. Potassium (K) is vital for good overall plant structure and controls a bunch of the plant’s processes such as the production of sugars, and water transportation. When used in conjunction with CANNABOOST the end result will be a yield with quality and size way above what you are used to. 

How and When to Use

  • Remember to always shake the bottle well before using.
  • CANNA PK 13/14 only needs to be added in a very small window of time. Dissolve 15 ml concentrate per 10 litres of water (1:666) and add to the root zone in the 3rd last week before harvest, for a total of 3 to 6 days. 

3. Organic Fertilizers

Canna also offers a 100% organic line for those who prefer growing organically, this line not only doesn't harm the environment but also provides everything at just the right amounts to avoid harming your plant either by under or overfeeding. Just like inorganic fertilisers, organic fertilisers have their own long list of advantages when it comes to growing high-quality cannabis. These products don’t just feed plants, but they nourish the very soil within which plants grow. You see, a healthy soil is teeming with beneficial life forms such as many different species of bacteria, fungi, nematodes, and protozoa.

High-quality soils also contain plenty of worms and micro animals that work to shred up organic matter. Overall, these critical life forms contribute to the soil food web—a network of food chains that facilitate the cycling of nutrients within the soil. Inorganic fertilisers can harm these creatures and cause them to disappear in the surrounding soil. Furthermore, plants work with these microbial allies in order to obtain nutrients; they work together in a mutual fashion. When fed inorganic nutrients, plants have no reason to help to keep these creatures alive and kicking. Therefore, taking the organic approach helps soil biology to thrive, which creates a healthy and fertile soil that will generate high-performing plants for seasons to come.

Bio Canna 

Bio Canna is Canna’s 100% organic certified products that can be used in any substrate of your choice, providing everything your plants need and in the right amount to grow fast and healthy.

Bio Flores

Bio Flores is a 100% organic fertilizer designed for the flowering stage, this product provides every nutrient your plant needs to not only develop more buds but also denser flowers while enhancing both the taste and aroma.

Bio vega provides everything your plants need for optimal veg growth.

Remember that if you provide ideal conditions and good-quality nutrients the buds will grow very dense and can be too heavy for the branches to withstand so this product will allow you to grow your plants without worrying about providing support during flowering.


Nitrogen (N)Phosphorus (P)Potassium (K)

Bio Rhizotonic

Bio Rhizotonic is a root stimulant for promoting root growth and providing a good environment for the roots to grow in, this product contains 100% natural ingredients that enhance root growth, helping your plants grow strong and getting them ready for the flowering stage.

Usage Tips

  • Shake well before using;
  • Feed 2-3 times a week to keep substrate fertile;
  • Use nutrient solution within 24hs after mixing.

4. Canna Feeding Schedule For Autoflowers (ml/L)

Now, using any of these products at full strength from the start may be too much for an autoflower so the best way to avoid any kind of problems would be to start with a lower amount, so this table was was designed with 3/4 of the recommended dose, this value may be increased or decreased according to the specific strain and growing environment.

Feeding Schedule For Autoflowers

Canna feeding chart: autoflowers


Also, if you are using one of their pre-amended substrates such as Canna Terra Professional, you should not start feeding from week 1, we recommend starting on week 3-4 of the vegetative stage but if you feel like your plants are hungry you can start earlier.

5. In Conclusion
