SKU: N/A Category:


Dr. Marijane’s advanced formula combines three strains of beneficial bacteria with a natural synergistic active to improve the bioavailability of your fertilizer program, strengthen the development and structure of plant roots, increase vegetative growth, and boost production. And because we care, we make it natural. It’s certified for organic production – which means no genetically-modified organisms and no synthetic chemicals.

How it Works

The three strains of highly functional beneficial bacteria were isolated by scientists from natural soils and selected based on their abilities to improve nutrient availability. We have combined the microbial strains with a unique all-natural synergistic active that enhances their activity, and helps to hold nutrients where the roots can use them. When Dr. Marijane is added to soil or soilless substrate the bacteria activate and begin to multiply, surrounding roots in a cloud of bioactivity.
