Great White Mycorrhizae contains a rich blend of beneficial microbes, including endomycorrhizal and ectomycorrhizal fungi, multiple beneficial bacteria and Trichoderma species, that work symbiotically with plant roots to improve nutrient and water absorption. When applied at transplanting, sowing or as a root drench, these microbes help roots explore the substrate more effectively and maximise the value of your fertiliser regime.

This premium mycorrhizal powder is fully water-soluble and easy to apply, giving you flexibility to use it in many ways, from dusting seeds and cuttings to top-feeding established plants or adding directly to reservoir water in hydroponic setups.

Key Features & Benefits

  • Enhanced Root Development: Mycorrhizal fungi form networks that extend roots’ reach into the growing medium, promoting faster, stronger root growth and improved plant stability.
  • Better Nutrient & Water Uptake: The microbial blend helps plants absorb more essential nutrients (especially phosphorus) and water, meaning your fertiliser feed goes further.
  • Beneficial Microbial Diversity: Includes multiple strains of endo and ectomycorrhizal fungi, beneficial bacteria and Trichoderma, all contributing to a healthier root zone ecosystem.
  • Versatile Across Systems: Great White works just as well in soil, coco coir and hydroponic systems, giving growers flexibility across different mediums.
  • Easy to Use: Water-soluble powder can be mixed with water for drenching, sprinkled directly on roots or used with transplants and cuttings.
  • Improved Transplant Success: Applying at transplant helps reduce shock and encourages quicker establishment of young plants.

How to Use

  • Seeds & Cuttings: Lightly dust seeds or cuttings with Great White before planting to encourage early root colonisation.
  • Transplants: Apply a thin layer of powder in the planting hole so roots make direct contact with the microbes.
  • Soil & Coco: Mix with water (about 1 scoop per ~25 L) and top-feed containers weekly or bi-weekly.
  • Hydroponics: Dissolve into your reservoir at a rate of 1 scoop per ~25 L and circulate with your regular nutrient solution.

Tip: Apply early in the plant’s life for best results; beneficial microbes are most effective when roots are actively growing.
