What to Think of for Hydroponics Gardeners

Hydroponics is a new way of soulless culture of plants, also known as nutrient solution culture. The core is to fix plant roots straight in the colonization basket inside which nutrient solution replace natural soil to provide plants with water, nutrients, oxygen, temperature and other growth factors, so that plants can grow normally and complete its entire life cycle.

With the advantages of intensive cultivation and precision, this kind of new technology cultivates plants which win the admiration of domestic and foreign plant consumers. These plants have the strong points of being clean, elegant and pollution-free. When plants begin to grow as seeds, a growing medium also plays an important part. It can be put on the bottom of a pot if we grow plants on soil, it helps to promote matrix ventilation and accelerate the leakage. In hydroponics, it helps to fix the root of the plants. Therefore, you should take it seriously as to what kind of growing medium you are going to choose. It is advisable to use gravel, peat moss, sand and the alike. We do not recommend using rockwool and we should definitely avoid using vermiculite, with which asbestos fibers are mixed to bring about disasters to one’s breathing system.

Throughout the life of plants, nutrients are quite important. They fall into two broad categories-macronutrients and micronutrients. Macronutrients refers elements whose total amount counts for more than one ten thousandth of the total weight of biological elements, including C, H, O, N, P, S, K, Ca, Mg and so on. Among all these, C is the most basic elements, C, H, O, and N as the basic element. The amount of C, H, O, N, P, S accounts for 97% of the total protoplasm. The first three are important components in organic compounds such as carbohydrates, protein, fat and organic acids, which are products of photosynthesis. Nitrogen constitutes an important element of protein, which constitutes the cell membrane, nucleus, the main component of various organelles. All these elements are quite important to plant growth. Micronutrients refer to elements which are needed by plants of a small amount but they play an irreplaceable important role.

Another thing that is of paramount importance is light. Different plants and plants of different growth period need different light. When in the growing stage, plants are most in need of blue spectrum light, which can be supplied by High Pressure Sodium (HPS) lights. When in the maturity stage, plants are most in need of red spectrum light, which can be supplied by Metal halide (MH) lights. However, since most plants experience these two stages, we need a light to cover these two stages, which can be fulfilled by LED grow lights.
