Use fertilizers that are designed for hydroponic gardening do not use standard fertilizers. The nutrients (or fertilizers) used in hydroponics systems are available in both liquid and dry forms, as well as both organic and synthetic.If your water doesn't meet this level, chemicals can be used to adjust the pH into the ideal range. The ideal pH level for water used in a hydroponics garden setup is between 5.8 and 6.2 (slightly acidic).Hard water that contains a high mineral content will not dissolve nutrients as effectively as water with low mineral content, so you might need to filter your water if it is high in minerals.If necessary, invest in a fan or air circulation equipment to improve the airflow. The best way to get carbon dioxide to your plants is to make sure the room has a constant flow of air. Your grow room should also have an ample supply of carbon dioxide your plants will grow faster.Consider a humidifier or dehumidifier to adjust the relative humidity. Higher humidity levels-especially in rooms with poor air circulation-can lead to powdery mildew and other fungal problems. The ideal humidity for a hydroponic grow room is from 40 to 60 percent relative humidity.And if the water temperature gets too high, it can lead to root rot. High temperatures can cause plants to become stunted. Ideal temperatures are between 68 and 70 degrees Fahrenheit.It is ideal for growing plant cuttings and plants with short growth cycles. It produces a high-output fluorescent light with low heat and low energy consumption. Halide bulbs emit a more orange-red light, which is great for plants in the vegetative growth stage. T5 is another type of lighting used in hydroponic grow rooms.

The best lighting for a hydroponics system is high-intensity discharge light fixtures, which can include either high-pressure sodium or metal halide bulbs.

Make sure to put your lighting system on a timer, so the lights turn on and off at the same time each day.

Most edible plants require at least six hours of sunlight each day 12 to 16 hours is better.
