10 Best Hydroponics Nutrients in 2022

Hydroponic plants derive the nutrients they need for healthy growth and flowering from a solution of water and minerals such as nitrogen, phosphorus and potassium. Different nutrient solutions will also contain Calcium, Chlorine, Molybdenum, Boron, Magnesium, Copper, Manganese, or iron depending on their purpose.

Traditionally plants get these nutrients from the soil which varies by geographical location and gets depleted over time. This isn’t the case with hydroponics because the amount and concentration of nutrients can be customized to the specific type of plant grown.
