Collection: Sumisansui Sumi Soaker Irrigation System

The Sumisansui Sumi Soaker is a Japanese-engineered irrigation system designed specifically for market gardeners, nurseries, and small-scale farms. Unlike traditional sprinklers that create dry spots and uneven coverage, the Sumi Soaker delivers a soft, uniform rectangular spray pattern that matches your bed layout — giving every plant exactly the right amount of water with zero waste.

Made from UV-stabilized polyethylene with a 21-mil wall thickness, these systems are built to last 10+ seasons in real field conditions. Each 328-foot roll can be cut to any length, so you can customize your setup to fit beds of any size. No complex plumbing, no expensive infrastructure — just connect to your water source and grow.

We carry two models to fit different growing situations. The Sumi Soaker R-Wide operates at 30 PSI and covers up to 30 feet wide, making it ideal for open field production where you want maximum coverage with fewer irrigation lines. The Sumi Soaker Mark II runs at just 11.6 PSI with a steeper spray angle, perfect for greenhouses, low tunnels, and irrigating around taller crops. Both models deliver gentle, rainfall-like coverage that won't wash out freshly seeded beds or damage delicate transplants.

Whether you're setting up a new market garden or upgrading from drip tape and overhead sprinklers, the Sumi Soaker system simplifies your irrigation while improving crop quality across the board.
