Firstly, I would recommend you to go through the Hydroponics guide for beginners. Now, let’s focus on growing vegetables regardless of season or climate, general hydroponics would be the right choice for you. As a hydroponic grower you can grow plants by simulating an ideal growing environment and monitoring certain important factors such as temperature, nutrients, lights, pH level, and humidity for your system of growing plants. As long as you maintain all these requirements, you can grow your plants regardless of the season.
If you are growing vegetables in summer, you need to bring your plants indoor especially if they are sensitive to high temperature. In summer, the temperature of your grow room should be between 70 and 80 ˚F and night temperatures should be a few degrees lower than daytime temperatures. Winter is the time to grow bigger plants and for that you need balanced HID lights for your grow room. You need to maintain the grow room ambient temperature in the ideal range of 70 to 75° F, when lights are on, and 66 to 69° F, when lights are off.
Try to maintain a healthy humidity level in your hydroponic grow room however an excessive humidity for long time may create conditions that are perfect for grey mold. You can get a device called a hygrometer that will provide information regarding the humidity level of your grow area. The most important thing you need to take care is grow room lighting. If your outdoor plants are not getting enough sunlight you need to install grow lights. By using artificial lights such as fluorescent bulbs, metal halide grow lamps, high pressure sodium lights, and high-intensity LED grow lights you can simulate the long days of summer for high growth level and slowly start reducing the light to replicate fall and induce the vegetable plants to start flowering.
