Product Description

Substra Flores

A direct availability and a correct composition of nutrients play a crucial role during the plant’s blooming phase. SUBSTRA Flores stimulates the fructification and contains all the nutrients that the plant needs during this phase.

During the blooming phase considerable less nitrogen is needed for example, but an increased need for potassium and phosphorous occurs. In addition, SUBSTRA Flores’ unique formula is rich in trace elements in a directly absorbable form. This results in an exuberant bloom.


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.

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. To prevent this from happening the nutrient should be specifically designed for such a system and preferably for 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.

CANNA Substra is one of the cornerstones that have helped CANNA to become world market leader.

About Substra

Tested for years

With CANNA SUBSTRA nutrition for fast growing plants, CANNA became a pioneer in the cultivation on substrates. With substrate cultivation, the soil is replaced by an inert growth medium. Inert growth mediums, such as rock wool, do not contain any nutrients. SUBSTRA is the best nutrition for growing on inert substrates. CANNA SUBSTRA is used especially on 'run-to-waste' systems; these are systems where the drain water is drained off. CANNA SUBSTRA has been the most used nutrient in the Netherlands for years.

Precision cultivation

With CANNA SUBSTRA growers have an optimum control over what their plants are offered. It does require more know-how than growing on 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 threatens to go wrong.

It is also important that there are no damaging ballast substances in the offered nutrition because this will have an immediate negative influence on the plant's development. Of course, CANNA SUBSTRA is free from these substances.

Hard and soft water

In order to make the nutrient supply as accurate and complete as possible, a distinction must be made based on the water quality. Among other things, the 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. The logical result of this is that, due to the difference in water composition, a hard as well as a soft water version of CANNA SUBSTRA is available.


Growing on inert mediums is still the most widely used growing method in the Dutch horticultural sector. With run-to-waste systems, the nutrient solution runs once past the roots and is then drained off. This means that the nutrient solution must have the correct composition.

Substra Flores Directions of Use

A ready to use fertilizer solution is made by diluting A & B concentrates in equal amounts with tap water. •Shake Substra Flores A and Substra Flores B well before use •Dosage: 40 ml / 10 Liter - 15 ml / US gallon (1:250) •Stir well and let mixture stand for some hours •Recommended pH: 5.2 - 6.2 •Recommended EC for Substra Flores A + B is 0.8 - 1.8 mS/cm (Part A plus Part B and assuming source water at 0.0 EC) •Water gift: 4 - 6 liter / m2 / day

Other directions •Never mix the A-concentrate directly with the B-concentrate, as insoluble combinations will occur •Keep out of reach of children •Store in a dark place •Keep away from extremes of hot and cold •Over fertilization has a negative effect on the nutrient mix and plant quality •Not to be used in protected nature reserves, reed beds or swampy areas, in hedges or small woods, in bodies of surface waters or near groundwater collecting areas •If the solution comes in contact with the skin or eyes, rinse with water
