Frequently Asked Questions

How and when should Premium Ultrafine Mycorrhizae be applied?

Mix it as a soluble powder for hydroponic feeding or a soil drench, ideally early in a plant's life or at transplant so the mycorrhizal relationship establishes before the root system is fully developed. It's built as an all-in-one product rather than requiring separate kelp or humic acid additions.

What does this product do for root health?

It's formulated to help establish symbiotic relationships between roots and mycorrhizae, supporting overall root system health and vigor. Growers use it as a way to build root-zone biology rather than relying on nutrient inputs alone.

What plants is this blend suited for?

It's described as great for soft-rooted plants such as fruits, vegetables, herbs, and flowers. That framing distinguishes it from soil-based inoculants intended for woodier or more established root systems.

How does this differ from GreenGro's Granular Plus Mycorrhizae?

Premium Ultrafine is the soluble powder version of this mycorrhizae blend, built for hydroponic and soil drench applications, while Granular Plus uses the same core formula in a granular format suited to soil-based application at transplant. Growers choose based on their growing system rather than a difference in the underlying microbial blend.

What size and packaging is this listing?

It ships as a 4oz package, sold in a case of 10, sized for the scale of root-biology program it's used on. Both sizes carry the identical mycorrhizae, bacteria, kelp, and humic blend.
