CANNA — Fertilisers and Additives > Fertilisers and Additives

CANNABOOST Accelerator boosts your plants’ metabolism*. This is important because nutrient uptake depends largely on plant health and metabolic rate. CANNABOOST is specially developed for plant species with a short life cycle.

• Denser, firmer fruit
• Suitable for all growing media or substrates
• Even better yields in combination with PK 13/14
• Improved ripening
• Better, richer flavour

The benefits of growing plants with CANNABOOST Accelerator are:

• Better yield. CANNABOOST stimulates the development of new flowers. As a result, fruit may become heavier than usual. Since ripening also proceeds more gradually, this results in a more uniform harvest. An especially noteworthy fact about CANNABOOST is that it does not guarantee higher yields, but it does guarantee better fruit flavour. An additional product for growers using CANNA products!
• Suitable for use with all types of growing media and substrates. CANNABOOST is a universal flowering stimulator, meaning it can be used in every growing system and with every type of nutrition without exception. In addition to being added to the substrate*, CANNABOOST can also be used as a leaf spray (foliar feeding). The advantage is that the plant can absorb the flowering stimulator directly through its leaves.
• Even better yields in combination with PK 13/14. CANNABOOST is not a fertiliser, but an additive that boosts photosynthesis. This ensures that fruit forms more quickly. Nutrient availability is very important for achieving optimal results with CANNABOOST. The availability of all nutrients is ensured by CANNA fertilisers. Even better results can be achieved by using CANNA fertilisers in combination with CANNA PK 13/14. This is because PK 13/14 provides the plant with extra elements needed for flowering, while CANNABOOST ensures the plant has the energy required to use these elements.
• Better ripening and a stronger immune system. CANNABOOST contains flowering stimulators that ensure abundant flowering. It also contains natural flowering regulators that support the development of more uniform fruit and a steadier finish to flowering. Thanks to improved energy regulation, the plant has enough energy to fight disease. If there is no energy where it is needed, diseases will attack frequently, precisely when this can be devastating to the harvest.
• Denser, stronger flavour. CANNABOOST guarantees higher yields and exceptional flavour. Today, a good harvest is not measured only by weight. Quality plays an increasingly important role, and that means flavour matters more too. Increasing the rate of photosynthesis greatly accelerates sugar production in fruit. This makes the flavour sweeter, while natural fruit aromas form at higher concentrations. A stronger scent of essential oils in fruit indicates a greater harvest volume.

Instructions for use:

• Shake the bottle well before use
• Dosage: Apply CANNABOOST at a ratio of 1:500 (20ml per 10 litres of water) from the moment flowers begin to form. For extra flowering power, dilute at 1:250 (40ml per 10 litres of water)
• Do not use in combination with products containing hydrogen peroxide (H₂0₂)
• Use diluted solution within 4 days
• CANNABOOST can be applied manually, through drip irrigation or as foliar feed

Storage, health and safety, and other guidance:

• Use CANNABOOST together with regular nutrition!
• Store closed, in a dark place; protect from freezing!
• Keep out of reach of children!

CANNA RHIZOTONIC is a powerful vegetative root stimulator for plants, made from seaweed. It contains numerous vitamins and is 100% natural. RHIZOTONIC adds over 60 organic substances that significantly accelerate the growth and balanced development of roots.

• Powerful root stimulator
• Rich in bioactive elements
• Boosts resilience
• Prevents stress
• Suitable for every growing medium

Benefits of CANNA RHIZOTONIC:

• Stimulates root growth in cuttings and transplanted plants. It not only stimulates root growth in already planted plants, but RHIZOTONIC also stimulates root growth in cuttings and transplanted plants. Various trace elements and vitamins, such as B1 and B2, stimulate hormone production and root growth, making the roots beautiful, strong and white.
• Accelerates germination when the product is used to soak seeds before planting. If you dilute RHIZOTONIC (40ml/10l), you can use it to soak seeds. RHIZOTONIC softens the seed coat, helping it split and germinate more easily.
• Enhances the plant's overall growth and chemical reactions to ensure a healthier, stronger plant. Good results start with a healthy plant. Because RHIZOTONIC stimulates root growth, it improves plant vigour. This is particularly important during the first weeks of a plant's life, when young plants are most vulnerable. RHIZOTONIC stimulates further root development, increases the plant's resistance to diseases and stimulates its internal and external strength.
• Helps the recovery process of all plants or cuttings subjected to stress of any kind. Many growers agree that plants recover much faster from stressful situations if their leaves have been sprayed with RHIZOTONIC. Such stressful situations may occur, for example, during transport or when repotting plants. RHIZOTONIC also improves the condition of plants that look unhealthy and poorly developed.

In addition, RHIZOTONIC is often used to spray plant leaves and, in this capacity, can be regarded as a conventional means of raising the pH* level in fertilizer reservoirs.

RHIZOTONIC can be used regardless of the type of growing medium. It is suitable for growing in potting mix and hydro-culture. You can use it throughout the entire growth cycle. From planting to harvest!

Instructions for use:

• Shake the bottle well before use
• Dissolve 40ml of concentrate in 10 litres of water (1:250)
• Spray directly onto the leaves 1-6 times daily until a strong root system develops
• After repotting the plant, water with a solution of the same concentration
• Adjust the pH level of the nutrient reservoir after adding RHIZOTONIC, as it slightly raises pH

Storage, health and safety, and other guidance:

• Excessive fertilisation has a negative effect on the substrate and the plant!
• RHIZOTONIC is 100% plant-based and suitable for all growing media, such as potting mixes, coco and hydroponics!
• Store closed, in a dark place; protect from freezing!
• Keep out of reach of children!

CANNAZYM is a high-quality enzyme* product that accelerates the breakdown of dead roots and activates beneficial microorganisms.

• Boosts resilience
• Provides vitamins
• Protects against bacteria and fungi
• Suitable for every growing medium

The enzymes in CANNAZYM offer many benefits:

• They convert dead roots into minerals and sugars. This is important because these minerals* and sugars are a valuable nutrient source for the plant. CANNAZYM contains more than 12 different types of enzymes, with added vitamins and desert plant extracts. These elements improve nutrient uptake and the plant's defence system. In addition, the vitamins stimulate hormone production.
• They help form new roots. The easily absorbed vitamins in CANNAZYM also stimulate the plant to produce new roots. This improves plant health.
• CANNAZYM prevents the development of bacteria and harmful moulds. Dead roots create an ideal environment for mould growth. They pose a threat to healthy roots. Moulds cause stress to the entire plant, young plants and all newly developing plants. In addition, CANNAZYM prevents rotting, so toxic substances do not form and the risk of disease is significantly reduced.
• CANNAZYM improves the growing medium. The rapid breakdown of dead root residues creates a balanced water regime and good aeration in the root zone.

CANNAZYM is indispensable when you intend to reuse growing substrates. Dead root residues are quickly broken down and converted into useful nutrients; the development of infections is prevented and the air-to-water balance in the root zone is improved. You can use CANNAZYM throughout the entire growth cycle.

Instructions for use:

• Shake the bottle well before use
• Dilute 25 ml of concentrate in 10 L of water (1:400)
• Add to the nutrient solution at least once a week, preferably continuously
• When using older (untreated) slabs, double the dose for one month
• Do not prepare the solution more than 4 days in advance
• Do not use in combination with products containing hydrogen peroxide (H₂0₂)

Storage, health and safety, and other guidance:

• Excessive fertilisation has a negative effect on the substrate and the plant!
• Store sealed in a dark place and protect from frost! The colour of CANNAZYM may change over time, but this does not necessarily mean that the product has expired!
• Keep out of reach of children!

If you want the biggest fruits and flowers, CANNA PK 13/14 is the right product for you. CANNA PK 13/14 is a blend of premium nutrient minerals* that stimulate flowering. The product is easy to use and provides high yields. PK 13/14 is suitable for all types of growing media. In addition, it only needs to be added once to the nutrient reservoir. If you do this at the right time, you will achieve amazing results!

• Increases yields
• Pure elements that stimulate flowering
• Abundant blooms
• Suitable for every growing medium

The benefits of CANNA PK 13/14:

• Pure flowering-stimulating elements. CANNA PK 13/14 is a highly concentrated blend of phosphorus* and potassium*, used during the flowering phase. Both elements play a major role during the plant's generative phase. Thanks to its special production process, CANNA has combined pure phosphorus and potassium in very high concentrations. This makes PK 13/14 a product that is delivered to the plant quickly and directly.
  Phosphorus (P) is a macronutrient for every plant. It plays an important role in metabolism* and energy transfer. During the flowering phase, an additional quantity of phosphorus is needed. Among other things, phosphorus strengthens cell formation in blooms.
  Potassium (K) is also a macronutrient. It is present throughout the plant and is required for a large part of its vital functions. Potassium is important for water and nutrient transport, and plant quality and resilience depend on it. It also controls numerous other processes, such as sugar production. The presence of potassium ensures that the plant can produce enough sugars during flowering, an important factor in bloom development.
• The ideal combination with CANNABOOST. During plant development, there comes a point when the need for phosphorus and potassium rises significantly. If CANNA PK 13/14 is applied at this point, you will meet the growing needs of the flowering plant and its fruits will reach their full development. CANNABOOST boosts metabolism and strengthens the effect of PK 13/14. This ideal combination will make the plant flower more abundantly.
• Suitable for every growing medium. PK 13/14 can be used with every growing medium: for cultivation in soil, in recirculating* systems, in coco and in systems with standard run-off*. PK 13/14 is suitable for indoor and outdoor growing.

User instructions:

• Shake the bottle well before use
• Add CANNA PK 13/14 three weeks before harvest to a full nutrient tank at the following rate: dissolve 15ml of concentrate in 10 litres of water (1:666). 

Storage, health and safety, and other guidance:

• Excessive fertilisation has a negative effect on the substrate and the plant!
• Store closed, in a dark place; protect from freezing!
• Keep out of reach of children!

CANNA Coco A & B is a complete fertiliser designed for professional growers cultivating plants in coco. It contains all essential elements for optimal growth and flowering.
Thanks to the special characteristics of the coco substrate*, CANNA COCO is not offered in separate Vega and Flores variants, but has a unique formula for both the growth and flowering phases. It could not be easier! CANNA COCO is easy to use, dissolves directly and is exceptionally suitable for growing plants in all irrigation systems, such as systems with 'run-to-waste'*, and recirculating* systems.

A product rich in high-value elements

• After years of scientific research into potting mixes* and analysis of drainage systems* and foliage, CANNA succeeded in becoming the first company to develop a fertiliser specifically tailored to the characteristics of coco substrates. CANNA COCO consists of high-quality minerals*. CANNA COCO contains natural chelates, humic and fulvic acids*, which enable the plant to absorb* nutrients in the optimal way. For years, growers around the world have expressed their enthusiasm for the exceptional growth and abundant flowering achieved with CANNA COCO.

Why are they called ‘A&B nutrients’?

• CANNA COCO nutrients consist of two parts—A and B. There is a reason they are separated. If certain elements in parts A and B are combined at the same time, they precipitate and the plant cannot absorb them. Therefore, you must first add component A and then component B!

User instructions:

• Shake the bottle well before use
• Fill the reservoir with water
• Add CANNA COCO A & B to the nutrient reservoir at a dilution ratio of 1:250 (40 ml A and 40 ml B per 10 litres of water). Add CANNA COCO A to the nutrient reservoir. Mix well, then add CANNA Coco B. Mix well again and leave the mixture to stand for several hours.
• The EC of Coco dissolved in tap water varies between 1.2 - 2.3 mS/cm² (= solution EC + water EC)
• Recommended pH: 5.5 - 6.2

Storage, health and safety, and other guidance:

• CANNA COCO nutrients can be used for both the vegetative and generative phases, unlike other (CANNA) nutrients!
• Do not mix A & B concentrate directly; insoluble combinations that the plant cannot absorb will result!
• Store in a dark place (UV light breaks down iron chelates in the nutrient medium); protect from frost!
• Keep out of reach of children!

CANNACURE is a unique foliar enhancer that prevents and controls pest and mildew outbreaks. It is eco-friendly and toxin-free. CANNACURE delivers healthier plants, larger flowers and higher yields.

The natural way to control pests

Mildew, whitefly, aphids, spider mites, mealybugs ... The world is full of diseases, pests and parasites looking for an opportunity to infect your plants and destroy your crop. Of course, you want to protect your plants in the best possible way. But how? Strong chemical pesticides may do the job, but they pollute the environment and poison your flowers and fruit. Yet, traditional methods of disease and pest control generally just do not work well enough.
CANNACURE is a product that has it all. Eco-friendly, it eliminates pests and mildew while stimulating growth and flowering.
CANNACURE is CANNA's first product for controlling pests and diseases. Developed in CANNA's research laboratories, it is unlike any other plant protection product because it is also a foliar enhancer. It provides healthier plants that can focus on producing large flowers and higher yields. It is not only CANNA scientists who are convinced of the product's quality. Since its launch, it has received praise from many growers.

How does it work?

When you spray CANNACURE, it forms a second natural "skin" on your plants. This layer improves the colour and vitality of the leaves while ensuring that the plants can still breathe. It makes them healthy, glossy and clean, enabling optimal photosynthesis. This allows the plants to focus on flowering.
Any plant pests will become trapped in the sticky layer, so they cannot damage the leaves. Ultimately, the pests will starve to death. Combined with other CANNA nutrients and additives, CANNACURE will help your plants withstand future infestations and diseases.

How to use CANNACURE?

It is very important to apply CANNACURE thoroughly to both sides of the leaves. Use CANNACURE once a week as a preventative measure to ensure that pests cannot attack the leaves. If you have a severe infestation of mildew, whitefly or spider mites, for example, spray every three days and repeat, if necessary, after another three days. Then continue spraying weekly as usual.
CANNACURE can be used from the start of growth until harvest, alongside your usual feeding regime.

User instructions:

• Dilute 330ml of concentrate per 1 litre of water
• Spray at least once a week, until harvest
• Apply with a fine sprayer to achieve maximum effectiveness

CANNA CALMAG AGENT is a special concentrate for buffering soft water. It can be used with all types of growing media.

To ensure an optimal mineral balance regardless of water quality, CANNA CALMAG AGENT provides a highly concentrated calcium and magnesium solution in the ideal ratio for exceptional plant growth. Ideal for correcting water sources with varying hardness, CALMAG AGENT supports consistently strong and healthy plant growth.

1. Ideal 3:1 Cal:Mag ratio
2. Highly concentrated
3. Improves poor-quality water
4. Improves nutrient uptake
5. Stronger, healthier plants
6. Reduces susceptibility to deficiencies and disease

Directions for use:

1. Shake well before use!
2. Fill the nutrient reservoir with water (20–22°C).
3. Add 0.1–1.0 ml CALMAG to 1 litre of water until you reach an EC of 0.4 mS/cm. Add your base nutrients and additives to this water.

What is your water quality?

• Water properties in Bulgaria vary across regions. CANNA TERRA and COCO nutrients are most compatible with normal water, usually with an electrical conductivity (EC) of 0.4–0.5.

According to conductivity levels, water is broadly divided into four different types:

1) soft water, 2) normal water, 3) hard water and 4) poor-quality water

What is the difference between soft, hard and/or poor-quality water, and what can you do about it?

1. Soft water has an electrical conductivity level of EC < 0.4 mS/cm. With CANNA CALMAG AGENT, you can raise your water’s electrical conductivity to 0.4 mS/cm.
2. Normal water has an electrical conductivity level between 0.4 and 0.5 mS/cm. It contains calcium, magnesium and bicarbonate to stabilise pH. CANNA TERRA and COCO base nutrients are designed to work best with this type of water.
3. Hard water (EC > 0.5 mS/cm) contains more calcium and magnesium than plants can absorb. When growing plants, the best way to treat this type of water is to use a reverse-osmosis filter, then mix the hard water with reverse-osmosis water until you reach an electrical conductivity (EC) level of 0.4 mS/cm.
4. Poor-quality water (EC>0.5 mS/cm) contains mainly sodium and chloride. These two elements can block the uptake of beneficial nutrients and become toxic to your plants. A reverse-osmosis filter can remove both elements. Simply preparing a mix of poor-quality water and reverse-osmosis water with an EC of 0.4 mS/cm will provide enough bicarbonates to stabilise pH, but calcium and magnesium levels will be too low. Prepare a mix of osmosis and tap water until you reach an EC of 0.2 mS/cm, then add CANNA CALMAG AGENT until you reach an EC of 0.4 mS/cm.
