Figure 1. Irrigation dye demonstration to compare wetting pattern of one single drip tape vs. two drip tapes on a bed at Pinney Purdue Vegetable Field Day (Credit: Irrigation educator Lyndon Kelley). The drip tape in the demonstration was 12’’ emitter spacing and 0.4 gpm/100 ft flow rate at 8 PSI and ran for an hour at 10 PSI.
