General
The easiest way for inexperienced growers to grow is using the CANNA TERRA line.
A substrate is a medium where the roots of the plants grow in.
a. The plant needs different proportions of nutrient elements in these different stages of development.
b. The plants acidifies the root environment when it starts to flower.
As soon as the first signs of flowers appear.
A & B together are the nutrients a plant needs. They are separated into a bottle of A and one of B to make the solutions as concentrated as possible. Always use A and B in equal amounts.
If A & B would be together in one bottle much more volume would be needed to dissolve the nutrients. Never mix concentrated A and B together since insoluble nutrients (gypsum) will be formed.
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.
Most CANNA products have a shelf life of two years, but there are some exceptions. Below you can find a list with the shelf life of all the different products.

We do not have samples of our products. The smallest size of bottles we have is 0.25 litres.
PH and EC
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.
But CANNA recommends a different range for each type of substrate:
| Terra | 5.8 – 6.2 |
| Coco | 5.5 – 6.2 |
| Others | 5.2 – 6.2 |
EC means electrical conductivity. EC is a number presenting the total of dissolved salts in the water. They include salts originating from the water and salts that are the nutrients added.
Additives
We recommend to use PK 13/14 always for one week! CANNA feeding already contains a certain amount of P and K. When the plant is in a certain stage of the flowering stage we can't increase the feed for the plant any more, so we change the PK-ratio by adding PK 13/14 for one week.
Trichoderma does not kill bacteria. It stimulates the root environment so roots can develop better and with more root hairs. As a result the plant gains more vitality and develops better.
Medium
There are many different substrates and growing methods, which roughly can be classified into four groups. CANNA sells different nutrients specifically developed for these different substrates or methods. The three groups are Terra (peat based mixtures), Coco (coco substrates) and for inert substrates Hydro (run to waste) and Aqua (for recirculation systems).
CANNA Terra Professional contains perlite and is made of black peat.
CANNA Terra Professional Plus contains tree bark and is made of white peat. For that it is a higher quality product.
System
CANNA specially developed CANNA AQUA for re-circulating systems. CANNA HYDRO should be used when using a run to waste system. Please do not mix those two up!
