växtnäringslösning

Växtnäringslösning, also known as nutrient solution or hydroponic solution, is a mixture of water and essential minerals that provides plants with the nutrients they need to grow. This type of solution is commonly used in hydroponic systems, where plants are grown without soil. The exact composition of a växtnäringslösning varies depending on the specific plant species and its growth stage, but it typically contains macronutrients like nitrogen, phosphorus, and potassium, as well as micronutrients such as iron, manganese, and zinc.

The primary purpose of växtnäringslösning is to deliver these nutrients in a readily available form for plant uptake through their roots. In hydroponics, the solution is circulated around the roots, ensuring a constant supply of water and nutrients. Careful management of the solution's pH level is crucial, as it affects the plants' ability to absorb different nutrients. Deviations from the optimal pH range can lead to nutrient deficiencies or toxicities.

Växtnäringslösning can be purchased as pre-mixed formulations or created by combining individual mineral salts. The concentration of nutrients in the solution, often measured in parts per million (ppm) or electrical conductivity (EC), also needs to be monitored and adjusted. By providing a balanced and optimized nutrient supply, växtnäringslösning allows for controlled plant growth and can lead to faster development and higher yields compared to traditional soil-based cultivation.
