Advantages of CANNA SUBSTRA

CANNA SUBSTRA is the best nutrition for growing on inert substrates such as rock wool. It is used especially on ‘run-to-waste’ systems; these are systems where the drain water is drained off or so called open-hydroponics systems.

SUBSTRA Advantages

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.

  • With CANNA SUBSTRA you can grow with precision. Growers have an optimum control over what their plants are offered. It does require more know-how than growing in soil for example, but higher yields can be achieved due to the fact that the nutrition absorption can be better arranged. Like this, immediate adjustments can also be made when something is about to go wrong.
  • There are no damaging ballast substances in SUBSTRA nutrition because this will have an immediate negative influence on the plant’s development.
  • CANNA SUBSTRA comes in a hard and soft water version. 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.

Hard and soft water versions

Not only should a nutrient be specially designed for run-to-waste systems, but 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. This ensures the exact 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.

Why A&B nutrients?

Both CANNA SUBSTRA nutrients (CANNA Substra Vega for the growing phase CANNA Substra Flores for the blooming phase) consist of two parts, an A part and a B part. We separate these parts for a reason. As it happens, if some of the elements in part A and B are thrown together at the same time, they precipitate out of solution becoming unavailable to plants. That's why you should first add the A component and then the B component.
