Netafim Woodpecker Junior Dripper, 1.0 GPH, 250 Pack
Equipping a whole range of benches calls for drippers by the hundred, all delivering exactly the same flow. This production bag contains 250 drippers, Netafim item 21520-001540, model 01WPCJL4N-B. They are WPCJ drippers with LCNL, coded grey with a black outlet for a nominal 1.06 GPH. Pressure compensation holds that flow constant from 10 to 45 psi. When the zone shuts off, the internal check valve seals at 1.75 psi. Lines stay charged between cycles, so the next irrigation starts evenly and nothing drains onto low plants. The nipple outlet connects directly to Netafim multi-outlet dripper assemblies. This exact dripper is the B component of Netafim flat 2-way multi-outlet assemblies. Pairing pressure compensation with the check valve, a combination known as PCNL, gives every plant the same water and fertilizer. Delivering water at the pot leaves foliage dry, which slows disease that spreads by splashing.
Scaling Up Potted Plant Production
On flat 2-way assemblies, one dripper feeds two pots at roughly 0.50 GPH each. Two hundred fifty drippers on 2-way manifolds therefore water 500 pots per bag. Uniformity of watering reaches 94 percent, even across rolling or sloped benches. Foliar sprays are not rinsed off by daily watering, which can cut spraying and runoff. Set each dripper into a 3 mm punched hole in the PE lateral and push it home. Run 120 mesh filtration and hold the zone near 35 psi for comfortable headroom inside the range. Use the same assembly type throughout a zone so flow per pot stays matched. At harvest, laterals with drippers attached roll up for storage and reuse. The grey color code makes it simple to sort these from other flows in the shop. Keep extras from the bag on hand for quick repairs during the season.
