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 22 up to 32 feet wide matches the layout of most farms and gardens
• Medium Pressure and Flow: Operates from 15 PSI up to 30 PSI MAX and from .086 - .128 Gallons per minute (GPM) per Foot of tube length

Gentle but Effective

• Sprays water at 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

How Much Area Does It Cover?

One line covers up to 32 feet wide which means it can water:

• 8 standard garden beds 30 inches wide + 18 inch walking paths
  
• 6 wider beds @ 4 feet + walking paths
• Multiple rows at once instead of needing separate sprinkler lines or multiple drip tape lines
• 45 degree spray angle goes wide but may not clear taller crops right next to the tube
  • add a Tube Holder and Riser kit for added elevation to clear tall crops

Money You'll Save

Setup Costs

• Less expensive than installing permanent sprinkler systems
• Fewer parts needed means faster and easier setup
