GreenPlanet Nutrients Backcountry Blend Boost

(N)0  (P)18  (K)19

Outdoor additive to optimize bloom production

This is a dry fertilizer additive that is used in the flowering stage.


Backcountry Blend Boost is a controlled release granular bloom additive. It can easily be applied to soil to provide your plants with a boost of PK during the flowering stage. Backcountry Blend Boost is designed to be used in conjunction with Backcountry Blend Bloom during the flowering stage.

Boost provides your outdoor plants with an extra dosage of phosphorus (P), potassium (K), and calcium (Ca), as well as an addition of humic acid. Phosphorus and potassium are vital elements that aid in the development of flowers and the movement of nutrients through the plant. Calcium plays a major role in cell wall composition and also helps maintain chemical balances in the soil. Humic acid aids in the movement of nutrients through the grow medium, making them easier for the plant to absorb. These added benefits improve overall yields, floral development, colour, and aroma.

This formula is designed to be top-dressed 3-4 weeks into the flowering stage.
