MPS Flexilink is suitable for irrigating existing installations.  The solution to planters with a shallow planting depth.

HOW TO USE THE MPS SECRET SOAKER

Normally a depth of 100 mm to 150 mm between root ball and the tanks is correct.  The type of plant is less significant than the type of soil. For coarse top soil, for instance, the tanks should be placed between 50 –100 mm from top of tank to bottom of the largest root ball.  In interior or better capillary soil, this distance can be increased to 150 mm.
  • Water reservoirs with a capacity ranging from 3.3 litres to 17.5 litres
  • Connectable in almost endless series
  • Solves problems with irrigation of slopes and alongside staircases
  • Excellent for irrigation of trees

Here is a sub-irrigation system made in England and of Swedish design, that uses capillary action to water your plants, bushes or trees in planters and gardens, large or small, indoors or outdoors. Capillary action is the rising of water naturally from the Secret Soaker to the plant above it, through the soil particles. The MPS Secret Soaker Sub-irrigation System has been in continuous use for over 20 years, including low temperatures in Sweden.

The MPS Secret Soaker “tanks” are placed permanently in the planters or gardens and covered with the correct form of potting soil mix to ensure proper capillary action. The trees, bushes or flowers are then planted, leaving a gap of about 10 cm (4”) between the top of the “tank” and the bottom of the plant's roots. Nutrients can be fed into the water, requiring only 25% of the nutrients normally used. As the water level in the “tanks” goes down, the oxygen is drawn down to the plant’s roots.

The system only uses 20% of the water used in a surface irrigation system. Water is drawn up through the soil by capillary action. Watering need only take place as little as every 4 weeks indoors and every 6 weeks outdoors, depending on location and temperature, but it is recommended that the systems be checked every 2 weeks. This means you can go away without having to worry about watering your garden. The MPS Secret Soaker has been  in operation in Europe for over 20 years and is a proven system. It has been used by individual gardeners and even more widely by municipalities to sub-irrigate large flower gardens.

BENEFITS OF THE MPS SECRET SOAKER
  • Water is fed to the plant’s roots by capillary action.
  • Air and moisture are constantly being exchanged at the root level. As water level goes down, oxygen is drawn to the plant’s roots.
  • The MPS secret soaker system uses only 20% of the amount of water used with surface irrigation of pop up systems.
  • Nutrients can be fed through the system without having them leach through the soil, saving nutrient costs.
