![]() ![]() It is a micro irrigation system where water goes directly to the plants roots. Trickle or Drip Irrigation for greenhouse How do drip irrigation systems work? It stops the formation of algae and spread of fungal diseases. That creates optimal growing temperature and dries the floor after the excess solution drains to the reservoir. Nutrients solution floods the floor through these openings and the excess water goes to the storage tank.Ī good idea is to set up a bottom floor heating system. A whole greenhouse floor is laid with concrete and slopes toward openings in the floor. In this method a sloped concrete floor is flooded and then drained. Moreover, the nutrient solution returns to the reservoir and can be reused. The water leftovers collect in a cross gutter at the low end. “Spaghetti” tubing supplies nutrient solution goes to the high end and flows through the base of the pots. Troughs are set up at slope from one end to other. Water flows through mounted on the bench or overhead of the greenhouse slightly sloping enclosures called troughs which contain pots. The gravity returns water to the reservoir and it can be used again. The basic principle of the Ebb and Flow system is that a tray with plants is filled with nutrient solution pumped out of the reservoir. ![]() It is a method of growing plants without soil by using a nutrients rich water solution. Ebb and Flow Greenhouse Watering SystemĮbb and Flow also known as Ebb and Flood or a flood drain is a simplest hydroponics system. That way you can ensure that your plants don’t get over or under watered. You can keep the mat permanently moist by using watering can or supply the water with drip lines.Īs the top layer of the soil continues to loose water in the evaporation process, the moisture is absorbed from the mat. The most common material for the capillary mat is thick cotton or polyester fabric. Source – Gardeners World What is capillary matting made from? Soil will continue to absorb water from the mat until it is evenly moist. Soil will absorb the water by osmosis and deliver it to the plant roots. First, you need to place a polythene sheeting on the bench. It is an improved version of the sand bench method. What are the types of sub irrigation?Ĭapillary Matting Greenhouse Watering System How does a capillary mat work? ![]() In contrast to the drip and misting irrigation where plants are watered from the above, in sub irrigation water is directed to the plants roots from below. Watering computer works when inserted in the compost sensors signal when irrigation is necessary. These can be switched on and off manually but you can use a timer or a complex water computer.Ī timer or a computer provide watering periods of different lengths on required days. The automatic systems work from the mainline either directly through a tap or indirectly through the reservoirs. Also, you will have to switch them on or off. In comparison to the automatic systems, here you have to fill the reservoir tank manually.
