Great White Nutrients is one of the most recognised and trusted mycorrhizal supplements in the entire hydroponics world. As part of the popular Plant Success range, it offers a strong and diverse blend of beneficial microbes that support bigger yields, stronger flowering and healthier plants.

Boost Growth With Premium Mycorrhizae

Great White Premium Mycorrhizae contains a rich mix of fungi, beneficial bacteria and root-supporting microbes. Because of this diversity, the product improves nutrient uptake, promotes strong root growth and supports better fruiting. When plants can access more nutrients and water, they grow faster and produce heavier, higher-quality results.

Easy to Use and Fully Water Soluble

Great White is fully water soluble, which makes it simple to apply in almost any system. You can add it during the early stages of growth to strengthen the root zone and help plants absorb every drop of water and feed. As a result, young plants become more resilient and establish themselves more quickly.
