Urea is a form of nitrogen fertilizer that can be used in hydroponic systems to provide plants with the nitrogen they need to grow. It is a slow-release fertilizer that can be added to the nutrient solution or applied as a top dressing.
When using urea in a hydroponic system, it’s important to follow the instructions on the label and use the correct dosage. A general rule of thumb is to add 1-2 tablespoons of urea per gallon of water. However, it’s always recommended to check the specific recommendations of the product you are using.
To add urea to the nutrient solution, it’s recommended to dissolve it in water before adding it to the reservoir. It’s also important to monitor the pH and EC (electrical conductivity) of the nutrient solution regularly and adjust as necessary to ensure that it stays within the optimal range for your plants.
Urea should be used with care as in high concentrations it can burn plants. Also, it is recommended to be used in the vegetative stage of the plants, as it can cause an excessive growth of foliage instead of flowers or fruits.
It’s also important to note that urea can cause an increase in the pH level of the nutrient solution, so it’s important to check and adjust the pH regularly when using urea.
