2 GPH PC Emitter on Stake, Antelco, Color Green

When you absolutely need to make sure all your plants get the right amount of water, you need a pressure compensating dripper. In addition to the standard internal labyrinth - used to regulate the flow rate of the dripper - they also include a silicone diaphragm, allowing them to react to pressure changes within the system and ensure a more consistent flow of water. This makes pressure compensating drippers ideal for systems with long runs of tubing, lots of hills, or a water source with inconsistent pressure output. Pressure compensation is only active between 8 and 50 PSI, so remember to use a pressure regulator to ensure proper function.

Special Feature: This dripper comes on a stake, which means it'll stand up straight without needing a separate stake. Due to this, it's best to use 1/4" tubing to connect this dripper into your 1/2" mainline instead of inserting it directly.

All drippers have a flow rate, which describes how much water will come out of the dripper in a given period of time. This is usually expressed in GPH, or Gallons Per Hour. A 2 GPH dripper like this one will emit two gallons of water over the course of an hour. 2 GPH drippers are a good "high flow" choice that you can use for thirstier plants or areas that need relatively more water than other areas in your garden.
