Hydroponic trays are typically black plastic containers that come in different sizes that can be used to grow crops indoors.  The nutrient solution from a system is evenly distributed across the surface of each tray before it’s placed under grow lights. In this way, the plants roots draw up water and nutrients from all around them for a constant supply without having to worry about everything being flooded or dry at once.  Hydroponics also allow us to control the chemical composition of the soil provided for a plant as well as providing a consistent temperature and availability of light so your plants never have to suffer from lack of sunlight, hail damage, drought or other variables which might cause difficulties during growth.
