Grotek Insta-Green 3-0-0 is designed to help growers with their crops when a nitrogen boost is required for plant development. The formula can help reduce yellowing and restore lush green colour to cuttings, seedlings or plants that are showing signs of underfeeding. An easy to absorb form of nitrogen assists with the effectiveness of the spray. With added iron, this formula provides nutrients that can restore the green to leaves in poor health.
