The mat watering system is a closed system. The boom extends from one side of the greenhouse bay to the other, propelled by an electric motor. This enables each seedling to grow in an individual cell when watering precision is extremely important.

For less critical applications, like woody ornamentals in large containers, a DU of 75 to 80 percent can be acceptable.īoom watering can function as either a closed or an open system that is used for producing seedlings grown in plug trays. For crops highly dependent on uniform watering, like plugs, a DU of 85 percent or better should be used. The best measure of a sprinkler system is a mathematical evaluation called Distribution Uniformity (DU). Pipes are installed above the plants and nozzles with varying spray ranges are installed to cover all plants. Overhead sprinklers are used mainly for crops that tolerate wet foliage. It is quite possible, in a well-designed system, to achieve uniformities of 95 percent. The most modern systems utilize a dripper, or even a pressure compensating dripper to assure each plant receives the same amount of water. The water is carried to each pot by a thin tube available in various sizes. What types of containerized-plant watering systems can be used in a greenhouse?Ĭontainerized-plant watering systems include drip, overhead sprinklers, boom watering, flood and float systems and pulse watering.ĭrip watering is a standard open system used when automatically watering potted plants. Bag culture of cut flowers is usually watered by drippers or spray stakes. The thin wall dripperline system is popular because long lengths of bench can be handled from a single header, and the humidity of the canopy is reduced, decreasing the incidence of disease. Perimeter watering is a plastic pipe around the perimeter of a bench with nozzles that spray water over the substrate surface below the foliage. The different types of fresh-flower watering systems are perimeter watering and thin wall dripperline, often called tapes.

What are the different watering systems for cut flowers? Further, this task is often left to the least skilled laborers, and the economic impact of careless watering on the quality of the plants can quickly be re-paid by most automated systems. Hand watering is considered uneconomical because it is labor inefficient, and automated systems are relatively inexpensive. Nutrients are not allowed to leach into the ground.Īn open irrigation system is any system for growing plants in which nutrient solution is allowed to pass through the root zone and out into the environment. There are both closed and open systems.Ī closed irrigation system is any method for growing plants in which the nutrient solution is recirculated. Generally they fall into the following categories: hand watering, sprinklers and mini-sprinklers, booms, sub-irrigation and drip. There are several methods and ways to water plants. What types of watering systems are there?

The result is a properly aerated system as well as healthy root development. You should water just before moisture stress occurs. A Closer Look at New Leaders at Dramm, Fine Americas, Source.Ag
