The garden box soaker watering kit is engineered specifically for efficient drip watering of one garden box of up to 64 square feet based on 12-inch row spacing. The layout configuration is 1/4-inch laser-drilled soaker tubing which carries the water in a fishbone pattern that uniformly waters entirely beneath the plant canopy in a very efficient way. The feeder line from the hose faucet to the garden box is 1/2" drip blank distribution tubing (sold separately). The Garden Box Drip Watering Kit includes: 3/4" FHT x 1/2" Drip-Lock 3-in-1 Filter, Pressure Regulator, and Drip Tubing Adapter , 1/2" Drip-Lock End Cap, 1/2" Drip Tubing Anchor Stake/Staple (5), 1/4" Drip Tubing Anchor Stake/Staple (24), 1/4" Barb Flag Dripper with Flow Control (12), 1/4" Laser-Drilled Soaker Tubing (50 feet), 1/4" Barb Drip Plug (12), and 3/4" MHT to 1/2" MPT Hose-to-Pipe Adapter in case you are using irrigation piping for the water source. Compatible with drip fittings from Orbit, Hydro-Rain, and other major brands, which makes the kit easily expandable. For outdoor irrigation use with cold water only.
