Gardeners will also want to try using the blue and red spectrum lights to increase growth and the flowering of their plants. The temperature control units may also come in handy once you decide how many plants you want to grow in your space. The more plants you have the hotter your greenhouse will usually be. The Benefits of Gardening the Hydroponic Way Gardening has been considered to be one of the most therapeutic rewards for North Americans. Gardening stimulates all of the senses, giving great satisfaction and pleasure. Hydroponics is the growing of plants without the use of soil. There are a variety of benefits associated with hydroponic gardening. Environmental control systems were being developed to help growers provide the ideal plant environment in addition to the ideal plant diet. Commercial crop growers are turning to soil less cultivation more and more. The speed of growth combined with the control over the growing environment means higher quality crops. The pH is the most important factor to monitor because the pH of a nutrient solution reads the outcome of an electrical battle between the roots and everything that surrounds them. The run off from growing plants in pots is the best place to measure the pH level. The protein and enzyme molecules in a plant are structured in very specific shapes in order to catalyze a chemical reaction to build the plant cells. The cards are useful for monitoring spider mites and many other small bugs. The bright yellow color will attract the spider mites where they will adhere to the sticky surface. The yellow cards are best for preventing the infestations of spider mites, but can’t act alone in eliminating them. It’s best to identify spider mites before their infestation grows too large, eliminating the spider mites with early detection will save your hydroponically grown produce. Plants can be propagated by a number of methods. The grower can let a plant go to seed, collect the seed, and start the cycle all over again, which is called germination. Another method is to take stem cuttings, also known as cloning. This process does not work with all plants, but it is considered a highly effective technique.
