Pack Rain

Appearance : Brownness granule

Main ingredient : Potassium polyacrylate


  • Absorb & store water when it’s raining;
  • Release water to plants when it’s drought.

How Does It Work?

Inner structure. It consists of a set of polymeric chains that are parallel to each other and regularly linked to each other by cross-linking agents, thus forming a network.

Absorbing water. When water comes into contact with one of these chains, it is drawn into the molecule by osmosis. Water rapidly migrates into the interior of the network where it is stored. That’s how PackRain turns to water gel.

Releasing water. As this water gel’s absorption ability is bigger than soil but less than roots of plants, the absorbed water by PackRain will be released to plants when it is dry.

Tips: the specific retention of PackRain is 1.3-1.4 MPa and the specific retention of roots is about 1.6-1.7 MPa.
