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 is non-draining, which means it has an internal valve inside that prevents it from letting water drain from the system. The internal valve opens at 4.3 PSI and closes at 2.2 PSI. This makes it a good choice for a greenhouse environment or a system with lots of hills or sloping terrain.

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 .58 GPH dripper like this one will emit half a gallon of water over the course of an hour. A slow flow rate like this is best for watering plants in soil with high clay content or plants that need relatively less water than other plants on the same system.
