This is a great dripper for hydroponic systems that works well under low pressure. Basket Drippers help oxygenate water by splitting it up into 6 grooves just below the cage. The stake also has a notch that shows how far to stick the stake into the growing medium. When using a strong pump, the water will actually spray out directly from the cage, making it an excellent spray stake for clay pellets. Doesn't clog as easily as other drippers. Easy to take apart and clean. Works with both the 0.15" or 1/4'' Drip Tubing.
