Know before you buy
While specifically formulated for the nutrient needs of lettuce, this bundle is suitable for a variety of vegetables. The 8-15-36 NPK ratio provides a strong foundation for leafy greens and other garden vegetables.
Because this product is not water-soluble, it is best suited for soil-based applications or as a top-dressing. If you are using a hydroponic system, you will need to ensure the nutrients are properly integrated into your growing medium or substrate.
Calcium and magnesium are essential secondary nutrients that lettuce requires in higher quantities to prevent tip burn and support cell wall strength. Keeping them separate allows you to adjust your dosage based on your specific water quality and plant growth stage.
No, this is a mineral-based synthetic fertilizer. It is designed for precision nutrient delivery and high-yield performance rather than organic certification standards.
To use as a foliar spray, you must ensure the fertilizer is finely ground or suspended properly in water. However, given that this product is granular and not water-soluble, it is primarily intended for soil application rather than direct leaf absorption.
