Application rate and directions
Apply 200–400mL per 100 m² of lawn in 5–15L of water. Use the lower rate for the first application.
- Measure the lawn area and calculate the required concentrate.
- Half-fill the spray tank with water.
- Shake the Green Light container, then add the measured concentrate while stirring.
- Add the remaining water and mix.
- Apply evenly across the lawn, using enough water for complete coverage.
Repeat every 14–28 days during the growing season, according to the product label. A watering can generally requires a higher water volume than a pressure sprayer. There is no need to water in after application.
