GreenPlanet Nutrients 3-Part GP3 Bloom (0-5-4)

GreenPlanet Nutrients 3-Part GP3 Bloom (0-5-4) is a professional liquid base nutrient designed to support plants during the flowering stage. As the bloom component of GreenPlanet’s GP3 3-part nutrient system, GP3 Bloom works with GP3 Grow and GP3 Micro to provide a complete feeding program from vegetative growth through flowering.

Formulated with a 0-5-4 NPK ratio, GP3 Bloom delivers targeted phosphorus and potassium support for bloom development, flower formation and overall flowering performance. It also includes magnesium and sulfur, helping complete the nutrient profile needed during this important stage of plant growth.

Bloom Nutrition for Flowering Plants

During the flowering stage, plants need a different nutrient balance than during vegetative growth. GreenPlanet GP3 Bloom provides a bloom-focused formula that helps supply the phosphorus and potassium plants need as they shift energy toward flower development.

When used with GP3 Grow and GP3 Micro, GP3 Bloom helps create a complete 3-part base nutrient program that can be adjusted according to plant stage, crop needs and growing conditions.

Part of the GP3 3-Part System

The GreenPlanet GP3 system is built around three separate base nutrients: GP3 Grow, GP3 Micro and GP3 Bloom. This 3-part format gives growers greater control over nutrition compared with single-bottle programs.
