Greenhouses are used in many regions of the world for the production of vegetables, fruits, and flower crops. The greenhouse offers the ability to manage the growing environment in order to increase control over quality and productivity. Because of the health rage in today's world, you will find most people building a greenhouse in their backyard because it is possible to build with relatively simple means. Your greenhouse has to be built in an area of the backyard in which plants are protected and can grow in temperatures and others environmental conditions that produce higher yield and healthier crops. The primary reasons for protected cultivation for your fruits and vegetables are the pest exclusion, protection from extreme solar radiation, and heavy rains and wind. Sometimes when your garden is planted in the open field, plant cultivation is often completely destroyed by severe storms and suffers from many pests and diseases. Under these circumstances, plants can be highly productive, but their fruits are generally not of the highest quality, or they may contain too many residues of plant protection chemicals. This is unfortunate, which is why it is important to locate an area that has more than enough available sunlight, and also, more than enough water.
