Indigrow has developed Magnum, our range of wetting agents. Magnum wetting agents can work in a number of ways. Curative wetting agents are designed to be applied to an existing hydrophobic condition, whilst preventative wetting agents are applied in the spring and repeated throughout the season to balance moisture in these potentially hydrophobic areas. Penetrant wetting agents open up the soil profile and allow excessive water to drain away and dispersant products help prevent the build-up of dew.
