Know before you buy
This formula is designed for the flowering and fruiting stages of plant development. Because it is low in nitrogen and high in phosphorus and potassium, it is ideal for promoting fruit sizing and firmness rather than leafy vegetative growth.
Yes, the high-purity, water-soluble formulation is suitable for both field and greenhouse applications. It dissolves completely, making it compatible with most fertigation and irrigation systems.
This is a quick-release synthetic fertilizer. It is designed to provide nutrients immediately to the plant, which is helpful when you need to address specific growth stages or nutrient requirements rapidly.
The 6% nitrogen content is intentional for late-stage growth. By restricting nitrogen, the plant shifts its energy away from producing foliage and focuses instead on developing larger, firmer fruits and vegetables.
As a water-soluble powder, it should be dissolved thoroughly in water according to your specific crop's requirements. Always ensure the powder is fully integrated into the solution before applying it to your plants to prevent uneven nutrient distribution.
