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.

But CANNA recommends a different range for each type of substrate:

CANNA TERRA5.8 – 6.2
CANNA COCO5.5 – 6.2
Others5.2 – 6.2

What is EC?

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 the nutrients added.

On the feedchart, what is the difference between EC+ and EC Total?

EC+ is based on when the EC of the water is 0.0. EC Total is based on the water at the EC specified in the Grow Guide. 

Do you need to use additional Calmag when using CANNA COCO?

Calmag is recommended when using RO water or soft water on coco substrate. It may also be used depending on plant genetics.
