Mint can be cultivated in hydroponics. To prepare a container suitable for the growth of plants, put clear water for one day, add appropriate nutrient solution, select healthy and complete seedlings without insects and diseases, cut off weak roots, put them in water, move them to the shade for maintenance, and properly trim the grown branches and leaves. It is normal for leaves to turn yellow after hydroponics, so don't worry.
