DAVID GRAYS AQUA WETT is a high performance soil wetting agent used to turn soils from hydro-phobic (water repelling) into hydro-phylic (water loving). Aqua Wett Soil Wetter allows rainfall and irrigation to penetrate to soil and be retained within the soil to be absorbed by the plant.

The sandy soils of Perth particularly will become hydrophobic, particularly around the lower coast plains of Perth. Ant activity will also cause soils to repel water, in garden beds and pots.
