How it works

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.

How to use it

Apply Backcountry Blend Bloom during the flowering stage at an application rate of  1 tsp/2 Gal of soil or approximately 1 tbsp for every 2 feet of plant height.

For incorporating the product into the soil, apply 1 lb per 10 cubic feet. This is a generalized feeding rate and may be adjusted based on your particular flowering needs.

Refer to our ONLINE NUTRIENT CALCULATOR for application rates during each week of plant growth.
