This pressure-compensating drip spike is useful wherever rising and falling elevations or long header hoses could affect pressure.
Attaches to 1/4" feeder lines coming off a header hose. Just 2 spikes, one on either side of the trunk, are often enough to water a small tree.
Also good for use with gravity-feed water sources such as rain barrels. Built-in insect baffles and filters help prevent blockage. Requires a straight connector and 1/4" feeder line to connect to header hose. Available in 1 gph and 2 gph versions.
