<p> 	These are great for watering long plant beds, planter boxes, and giving large plants an even amount of water in a circle around them. They connect to a Tropf-Blumat or a Maxi.This is less expensive than adding more sensors but you may need to add a filter to your system so they don't clog. This pack contains 10 distributors and 2 meters of (6.5 feet) of 3mm drip tubing. Two nozzles allow you to connect tubing on both sides of the dripper for up to five drip locations from one Tropf-Blumat (dripper chain). The end-distributor dripper has a drip nozzle on one side only for use as the end piece in a dripper chain.</p> <p> 	<span style="font-family: arial, sans-serif; font-size: 13px;">You can go as far as 100 cm (39") from the sensor with these and they&nbsp;</span><span style="font-family: arial, sans-serif; font-size: 13px;">water about 20 cm wide (8"). Minimum pressure to use them like this is&nbsp;</span><span style="font-family: arial, sans-serif; font-size: 13px;">4.,5 psi. You&nbsp;</span><span style="font-family: arial, sans-serif; font-size: 13px;">can go down as low as 2 psi but the last dripper or two might not put out much water.</span></p> <p> 	&nbsp;</p>
