You can vary the amount of water to give your plants as they grow. 8 streams, easily adjusted from about 5" throw to 2-3 feet depending on pressure available. Very minimal water use as virtually all goes to the plant. Excellent product for drip irrigation. I did a pressure step down on my sprinkler system to 25 psi before using these.

These have been great for my hanging baskets you can have the water 0 to 10 gph what ever is best for your plants.
