How It Works
The Tropf Blumat self watering system functions fully automatically. As the soil dries, its natural suction power triggers the water outlet in the Blumat Sensor allowing the water to flow. When the soil is sufficiently moist, the Tropf Blumat automatically stops. It makes no noise and does not spray.

Each Blumat outdoor sensor covers an area with a 12” diameter. To create your own large-scale irrigation system, just add additional supply hose, outdoor sensors, and distributor drippers.

Take the Guess-work Out of Watering Your Plants
  • Maintains the ideal moisture level for each plant
  • Automatically stops the watering when soil moisture reaches your adjusted setting
  • Automatically turns the water back on when soil or potting mix reaches your preset level
  • Automatically changes when plants grow faster or slower, it rains, gets hotter, windy, colder, or humidity changes
  • More accurate than expensive irrigation timers because each individual plant monitored – not an entire zone

Saves Huge Amounts of Time
  • Go on vacation without worrying about your plants

Perfect for Hard-to-water Locations
  • Quickly solves the challenge of watering hanging plants – you can run Blumat line 30’ higher than the water source
  • Makes watering planter boxes on balconies easy and fast
  • Simple to add a tiny, almost unnoticeable water line to a location far from your irrigation lines
  • Saves Natural Resources
  • Saves huge amounts of water being wasted
  • Stops wasting expensive fertilizers that wash away with over-watering
  • Saves the waste of “throw-away” components that easily clog or break – Blumats last for years and years
  • Saves power generation and limits pollution – Blumats don’t need any electricity or batteries!

Plants Grow Better
  • Plant growth momentum not stopped by too much or not enough moisture
  • Too much water squeezes out important soil air pockets that let plants “breathe”
  • Not enough water kills small, sensitive feeder roots
  • Too much or not enough harm beneficial microbes that keep soil alive and vital
  • The slow drip lets water in main lines warm up in the sun
  • Plants don’t get a cold shock that stunts growth and health
  • Nurtures the conditions for plants to achieve their most healthy, thriving, and productive potential
  • Produces higher yields and quality
