With oriental cuisine becoming more and more popular, pak choi makes a wonderful addition to your greenhouses. This leafy plant, a type of Chinese cabbage, grows quickly, is fairly simple to keep happy and is not prone to insect infestations when grown in a greenhouse. Two of the most important components in pak choi production are light and ventilation. Read on to find out how you can successfully grow pak choi in your hydroponic garden.

Growing pak choi takes approximately thirty-five days from planting to harvest. This allows growers to produce several crops per year. The growing cycle is divided into two parts, with the germination period being ten days in length and then re-locating the seedlings to grow to full size. During the germination period, light is provided to the plants for twenty-four hours a day. It is not recommended that a gardener use incandescent lamps during this stage, but instead use fluorescent lighting. This does serve a major purpose. Incandescent lights emit red waves, which can cause the plants to grow tall and spindly. Fluorescent lights, which emit blue light, will help stalks develop shorter and thicker, providing a strong base.

The nutrient film technique (NFT) is the most popular used for growing pak choi once it has been moved to its final growing area. The proper amount of overall, even light is necessary for the growth of plants.High-pressure sodium lamps are the recommended grow lights for this final growing stage. These bulbs not only put forth the correct color of light, they enable an even distribution of light.
