SubCulture B is a biological root inoculum that contains 52 constructive gardening microorganisms. 

This revolutionary blend of beneficial bacteria, actinomycetes and trichoderma fungi colonize in the root zone and growing media to form a symbiotic relationship with your plant.

This symbiotic partnership increases your plant's root mass for improved nutrient absorption, resulting in larger, healthier plants. You'll also find your plants will be more resistant to environmental stress.

SubCulture B works well with both soil and hydroponic gardens!

Good news! New packaging has eliminated the restricting pouches. Now it's easier to measure the powder for your exact requirements!

SubCulture B can be used throughout the growing cycle. Created by General Hydroponics - a trusted name in the industry.
