In hydroponics, a two-part nutrient solution is often used for growing tomatoes. This type of solution is known as “type A and type B” and it contains all the essential nutrients that tomatoes need to grow and thrive.
Type A solution: This solution is typically high in Nitrogen ( N ), Phosphorus (P), and Potassium (K) and it is used to promote vegetative growth, leafy growth and root development.
Type B solution: This solution is typically high in Calcium (Ca), Magnesium (Mg), and Sulfur (S) and it is used to promote fruiting and flowering.
The ratio of the two solutions can be adjusted depending on the stage of growth of the plant. For example, during the vegetative stage, a higher ratio of Type A solution is typically used, while during the fruiting stage, a higher ratio of Type B solution is used.
It’s also important to note that the specific nutrient requirements may vary depending on the variety of tomato and the specific growing conditions. It’s always best to consult the specific nutrient requirements of the variety you are growing, and to monitor and adjust the nutrient levels as needed. It’s also essential to check the pH and EC of the nutrient solution regularly, to ensure that the plants are absorbing the nutrients properly.
