Physiology of Plants
To achieve good results, a home grower must know about plant physiology. Plant physiology is the part of biology which is concerned with the way plants grow and flower. In this chapter, the principles of plant physiology are discussed. With the growth and flowering of plants, it involves a select combination of light, air, and water. For light, it’s about sunlight for outside growing, a combination of sunlight and artificial light for greenhouses, and just artificial light for inside growing. For air, the amount of carbon dioxide (CO2) is of principal importance. Water performs various functions. Plants need water (H2O) for the growth process, but also to transport other important materials.
