Irrigation Dripper tube, or drip line, is a length of pipe with inbuilt drippers positioned evenly along its length. Dripper tube can also be used in longer lengths than soaker hose and the drippers are usually pressure compensating to deliver water more evenly along the entire length, even when going up a hill. Economy drip line usually has drippers at wider 50cm intervals. Buy Anti-Siphon drip line if burying underground, to stop soil being siphoned back into the dripper, blocking it. Don't forget to buy pegs to hold it down, as it is quite stiff when uncoiled, and an end piece. Use connectors to build irrigation grids and systems.
