CANNA SUBSTRA FLORES SW A/B 5 LTR

CANNA® Substra is the nutrient for systems in which the drainage water is not returned to the nutrient tank but drains away (Run-to-Waste / Open hydroponic systems): the most popular cultivation method in the Netherlands and CANNA® Substra is the nutrient that is most used for this system.
In these types of systems, the plants roots are in direct contact with the nutrient solution. Because the plants do not absorb all the nutritional elements with equal speed or in equal amounts, the composition of the nutrient solution will change over time.  CANNA® Substra has a balanced quantity of all nutritional elements needed by plants. As the substrates used in run-to-waste systems are mostly inert (They don't add or take nutrient elements from the nutrient solution) all the nutrients have to be in the nutrient solution. An excess of nutritional elements can lead to plant damage but they will also end up in the environment.
