What is Sumisansui Irrigation?

Sumisansui products are a high quality and durable irrigation system that sprays water in a perfect rectangle pattern instead of circles like traditional sprinklers. It's been trusted by farmers and gardeners worldwide for almost 40 years.

The Sumisansui Winder and Bobbin system allows farmers and gardeners to quickly deploy the irrigation system when and where your plants need watering.

Why It's Better Than Regular Sprinklers

Perfect Water Coverage

• Efficiency: No dry spots or overlapping wet areas like circular sprinklers
• Good Fit: Coverage from 3 feet up to 32 feet wide matches the layout of many different farms and gardens
  
• Low Pressure and Flow: integrates well with any irrigation system including drip tape
  
  • R Series - Operates from 15 psi up to 30 psi MAX and from .086 - .128 Gallons Per Minute (GPM) per foot of tube length
    
  • M Series - Operates from 3 psi up to 12 psi MAX and an average flow rate of .036 - .044 Gallons Per Minute (GPM) per foot of tube length
    

Gentle but Effective

• Sprays water at 0.22 to 0.45 inches per hour - just like a gentle rain
• Soft enough that it won't wash away seeds and soil or damage plants
• Water soaks in properly instead of running off

Perfect for Different Types of Growing

Starting Seeds

• Gentle mist won't wash out tiny seeds like carrots or lettuce
• Even moisture helps more seeds sprout successfully
• Keep seeds moist during critical growth stages
• Customers see improved germination rates

Transplanting Young Plants

• Soft spray reduces shock to newly planted seedlings
• Helps plants establish faster
• Reduce plant losses from drying out

Fast-Growing Crops

• Easy to move between different planting areas
• Great for salad greens and microgreens
• No permanent pipes to work around

Alternative Uses

• pre harvest wash and plump up lettuces and greens while they're still in the field
• cooling greenhouses during intense summer weather
• blast spider mites off of your greenhouse cucurbits
• keep compost windrows at the proper moisture level
• water shiitake mushroom logs and other outdoor mushroom projects
