1. What is the best and easiest growing method for starters?

CANNA produces 4 different nutrients for 4 different growing methods. All have advantages and disadvantages and depend mostly on the growers ability and experience. Of the 4 growing methods the easiest for starters are the CANNA Coco and Terra lines. The corresponding substrate has extra benefits added deigned to reduce mistakes. Using Coco or Terra according the grow guide will always give a wonderful yield with minimum attention required.

2. What is a substrate?

Substrates have 2 main functions. The first being to hold the plant in place for optimal growing. The second depends on the type of substrate. Substrate such as TERRA, COCO, potting mixes and soil also hold water and nutrients that can be available to the plant roots. The substrates will hold the nutrients that are ready to use or through chemical processes they will convert the nutrients into a form the plants can use. Inert substrates like clay balls, rockwool or sand do not have those capacities and simply function to hold the plant. Roots in these systems need to be kept humid all the time.

3. Why are there different nutrients (VEGA and FLORES) for the Growing phase and Flowering phase of the plant cycle?

Plants require different amounts of certain nutrient elements at different times during the plant cycle. During the Growing or Vegetative phase the plants need additional nitrogen, calcium and magnesium for strong growth to get the plants quickly to the desired size. During the flowering phase the plants need additional Potassium and Phosphorous for good flower and fruit development. If all elements would be together in 1 solution the balance in the root environment is disrupted causing deficiencies. Only with Coco A&B nutrients all elements are in the same bottle because of the unique buffering characteristics of the Coco substrate.

4. When do I know when to start giving my plant the flowering nutrient?

Plants require the flowering nutrient as day lengths become longer or shorter depending on your crop. Plants such as chillies and tomatoes that normally flower and fruit during the summer months start to flower as the day length becomes longer. For plants that flower during the autumn/ winter months, such as citrus and brassica's, they start to flower as the day length becomes shorter. For outdoor plants this will happen naturally with the seasons. Indoors this happens with changing the amount of time the lights are on. The flowering nutrients should be given when the day length becomes shorter or longer depending on your crop.

For indoor gardeners the sign of flowers may not appear until the day length is changed with the exclusion of auto flowering plants. Change the light cycle first then start your flowering nutrient.

5. Why do some nutrient lines have an A&B formula? What does it mean?

Some nutrients are divided into two bottles, an A&B, because in a high concentrated form the elements in these solution react with each other if mixed together. Then precipitation occurs and the nutrients are not available for uptake by the plant any more.

The use of A&B nutrients must always be mixed in equal amounts. Add A nutrient first, stir, and add B nutrient and stir again.

>When using measuring equipment make sure you clean it in between measuring both A and B. If any solution is left in the equipment, the elements will bind. Alternatively separate equipment for A and B can also prevent binding of nutrients.

6. What is the biggest difference between mineral nutrients and biological ORGANIC nutrients?

The biggest difference is their origin, which is the reason why the organic nutrients can be used for organic growing. Biological (organic) nutrients are released slowly. Mineral fertilisers are available from the start. The ingredients of the nutrients and additives are sourced from different origins, which is the main difference.

Mineral nutrients are inorganic salts made from mineral sources and are directly available to the plants for plant growth and bloom.

Organic nutrients are derived from organic sources such as plant and animal materials and can work as a slow release nutrients through reactions with the substrate and any micro organisms in the mix. For more information see article Organic/ Mineral, what´s the deal?

7. I want to try CANNA products can you please send me some samples?

At CANNA we have done testing and development of our products for almost 30 years, along with almost 30 years of satisfied gardeners from around the world. This makes us believe our products meet the growers and plant needs. For distribution of our products we rely on our loyal retail stores who are fully capable of giving proper advice and explain the benefits of our products. As a company we do not want to bypass our loyal retailers, we do not provide products to individuals. Also we believe in the products and in the growers capacity to successfully get their return on investment. We believe our quality will prove itself.

8. What is the importance of pH measuring?

pH has a great influence on the availability of the different nutrient elements. Therefore be sure the pH is always in the right range. The best availability range in the substrate is from 5.2- up to 6.2.

9. What is EC?

EC means Electrical Conductivity. EC is the concentration of salts in the water or nutrient solution. Water quality varies depending on the water source or conditioning (ie. RO water) and should be tested prior to adding nutrients as it may effect the EC of the nutrient solution applied to the plants. Which can then affect plant growth by adding to much or too little.

10. What kind of substrate should I use?

The type of substrate will depend on your system and growing experience. Some substrates are easier and more forgiving to use while others are more intensive. Choose your system or substrate based on these parameters. For new gardeners just starting out the recommendation would be for using CANNA TERRA or CANNA COCO as there are fewer chances of making mistakes. For more advanced growers CANNA SUBSTRA or CANNA AQUA might be more suitable for your skill level. This is all more or less a matter of growers preference and skills. There is no substrate type better than others. It all depends on your preferred growing system.

11. Where are CANNA products manufactured?

The CANNA products are processed and manufactured in the Netherlands at our state of the art facilities. Over here we are 100% sure to be able to secure the highest standards for manufacturing our products. The factories are designed for optimized processes and low waste material. The facility is certified EKO for processing organic input.

12. Why does CANNA use a date on their products?

A common misconception is, that the date on the CANNA products are shelf life or only best before date. Although the date does represent a best before indicator, the product can still work as per its intended use. During manufacturing a date is added to add another level of transparency to the customer. All products age and can loose potency over time. The date is simply to guarantee the working properties are at its full strength during this period. After that date, depending on the severity of the conditions such as climate and what else that the product has been exposed to, we can only speculate the potency. CANNA is therefor of the mindset, that it has no control over the conditions after the time it left the facility and that date. However with CANNA, you always know the information you need regarding freshness of your products, so this is merely to provide extra information, and to determine if most extreme conditions could be effecting your success rate in using CANNA products after such date.

13. Where can I purchase CANNA products?

CANNA products are available through local retailers, as can be found in our store locator.

14. I am a retailer and want to sell CANNA Products, who should I contact?

You can send in your request through the retailer form. CANNA works with a local distributor in South Africa for supply of our products.

15. When will the CANNA Products be available in South Africa?

CANNA does not take shortcuts and is registering its products according to legal requirements in South Africa. We work with DAFF on the registration and hope to be able to import products soon. Keep an eye on the website and social media for new.
