Direct-to-root delivery
Water, air and nutrients reach the active root zone – catalog-stated design purpose.
Downward root growth
Encourages deep rooting instead of surface roots – better drought survival.
Zero runoff
Below-grade distribution loses nothing to evaporation or slope.
Filter basket
Perforated strainer keeps coarse media out of the tube.
