Irrigation Fittings & Pipe

How to build a custom Hydroponics in door Gardening – Irrigation System.
When designing an irrigation system the first thing to consider is the Pump you will muse. Choose a Pump based on the lift ( the maximum height the pump will have to move the water) the volume of the water you need to move.
Next choose the supply pipe that will transport the water form the pump to the dripper line. Hollands Hydroponics stocks supply pipes on 12mm, 16mm and 20mm diameter. reducers can be used to change the pipe diameter if the size pipe that fits the Pump is different to the size of pipe you want to use in the rest of the system.
Tees and Elbows and X-Connectors can be used to change the direction of the supply pipe or split it up into different paths. Stop ends are used to block the end of the pipe. To make it easyer to insert these fittings, soak the pipe in hot water for a few seconds to soften the plastic.
The Drippers which sit in the plat pot and supply the water to the plant are linked to the large diameter supply pipe via smaller diameter dripper line. To attach the smaller diameter dripper line to the large supply pipe several options are available. Insert Nipples allow the attachment of a single dripper line. If you want to have more Drippers coming from a single point you can either use a 4-Way Manifold with attaches into the large diameter supply pipe in the same way as an insert nipple, or a 8-Way Manifold, which screws into a female BSP Tee and the supply pipe that the insert nipple and the 4-Way Maniford can fit into.
Drippers fit on to the end of the smaller diameter dripper line and are what finally supply the Nutrient solution to the plant. Arrow Drippers have the flow limited to 2l/h and are suitable for the use with Soil and Coco. Flood Drippers are not limited and are suitable for mediums which hold very little water such as clay pebbles. Octamitter Drippers are another style of dripper, these are adjustable, allowing you to set the flow rate between 0-40 l/h.
The final thing to consider is if you want the system to be recirculating where the excess Nutrient solution that comes out of the bottom of the plant pots is returned to the nutrient tank. or run-to-waste where the excess nutrient solution that comes out the plant pots is discarded and never returns to the plant.
