GreenPlanet BackCountry Blend Boost (0-18-19)

GreenPlanet BackCountry Blend Boost (0-18-19) is a controlled-release granular bloom additive designed to support outdoor plants during flowering. With a powerful 0-18-19 NPK formula, this dry PK booster delivers phosphorus and potassium to help support flower development, nutrient movement and overall bloom performance.

Part of the GreenPlanet BackCountry Blend Outdoor Feed Program, BackCountry Blend Boost is designed to be used alongside BackCountry Blend Bloom. It is an excellent choice for growers who want to strengthen their flowering program with an easy-to-apply dry additive that can be top-dressed directly into soil.

High-PK Support for Flowering Plants

During the flowering stage, plants need increased phosphorus and potassium to support flower formation, energy transfer and nutrient movement. BackCountry Blend Boost is formulated with 0% nitrogen, making it a focused bloom-stage additive for growers who want extra PK support without adding more nitrogen to their feeding program.

Phosphorus supports flower development and plant energy processes, while potassium contributes to nutrient transport, plant strength, and flowering performance. Calcium supports cell wall structure, while humic acid helps improve nutrient movement through the growing medium.

Designed to Use with BackCountry Blend Bloom

GreenPlanet BackCountry Blend Boost is not a complete base nutrient on its own. Use it with GreenPlanet BackCountry Blend Bloom during the flowering stage.

BackCountry Blend Bloom provides the base flowering nutrition, while BackCountry Blend Boost adds an extra dose of phosphorus and potassium to help enhance the bloom feeding program. This makes it a strong companion product for growers already using the BackCountry Blend Outdoor Feed Program.

How to Use

Use GreenPlanet BackCountry Blend Boost (0-18-19) during the flowering stage according to the official GreenPlanet BackCountry Blend Feeding Program.
