CANNA Substra Vega is a complete professional nutrient for the growing phase of plants. It is specially developed for growing in inert run-to-waste systems. In the beginning of the growing phase, the plant lays the foundation for its eventual yield.
If you grow on a run-to-waste system, you need a plant nutrient that exactly suits the needs of this special growing method. The substrates used in run-to-waste are mostly inert (which means they don't add or take nutrient elements from the nutrient solution). So 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. CANNA SUBSTRA has a balanced quantity of all nutritional elements needed by plants.
CANNA SUBSTRA comes in Hard Water & Soft Water versions. In order to make the nutrient supply as accurate and complete as possible, this distinction must be made. Among other things, water quality has an effect on the availability and the supply of nutrients. For example, there are more nutrients dissolved in hard water compared to soft water (e.g. magnesium and calcium) and more acid is needed to set the pH. This in turn influences the availability of the other nutrient elements.
Not only should a nutrient be specially designed for inert run-to-waste systems, it should also match your type of tap water. That’s why CANNA developed a hard and soft water version of the SUBSTRA nutrient line. With this choice, the correct amount of nutrients will be delivered to the plants root system and as little as possible nutrients will end up in the drain water; healthy for the consumer and great for the environment.
