Great White Granular 1 – Organic Mycorrhizal Inoculant

Great White Granular 1 is the most affordable organic mycorrhizal product available, providing a cost-effective solution for gardeners looking to boost plant performance. This OMRI-listed and OIM-registered inoculant is specifically designed to add beneficial microorganisms to the root zone, enhancing plant vigor and increasing the efficiency of water and nutrient uptake. Whether you are tending to a vegetable patch, an orchard, or a floral garden, Great White Granular 1 provides the biological foundation needed for success.

The active endomycorrhizae in this formula creates a symbiotic relationship with your plant’s roots, effectively extending the root system’s reach. This leads to improved drought resistance and a more resilient garden. Because it is a granular formula, it is incredibly easy to apply during transplanting or as a top-dress for existing garden beds.

FAQs

Can I use this in a hydroponic reservoir?
No. As a granular product, it is designed for soil and coco applications. For hydroponic systems, we recommend using the water-soluble Great White Premium Mycorrhizae.

How long does it take for the mycorrhizae to work?
Once the granules touch the roots, colonization begins almost immediately. You will typically see improved plant resilience and growth within 2–4 weeks.

Do I need to reapply?
For short-cycle plants, one application at transplanting is usually sufficient. For long-term perennials or fruit trees, a yearly “top-up” using the hole-probing method can help maintain the colony.
