Drip Tubing, Emitters & FittingsOUR TAKE
Rain Bird SW20-30PS two-GPH emitters, thirty-pack
Thirty pressure-compensating, two-gallon-per-hour spot-watering emitters.
A row of containers is easier to water evenly when you can put an emitter at each root zone. These two-GPH emitters suit a planned drip layout with the right tubing and supply setup. Test the flow into a container before deciding how long the plants need the system to run.
