🌱 Great White Premium Mycorrhizae Beneficial Bacteria — Guide and Product Information
Product Overview
Great White Premium Mycorrhizae Beneficial Bacteria is a microbial inoculant formulated to populate the root zone with a wide range of beneficial fungi and bacteria. It combines 7 species of ectomycorrhizal fungi, 9 species of endomycorrhizal fungi and 14 species of beneficial bacteria to help create a more active rhizosphere around the roots.
Used as part of a balanced feeding routine, it can help support stronger root development and improve how efficiently plants make use of available nutrients. It is suitable for growers working in soil, coco or hydroponic systems and looking to strengthen root-zone performance throughout propagation, transplanting and ongoing growth.
Why Growers Use Great White
The root zone has a major influence on plant health and overall performance. By introducing beneficial microbes where they are needed most, Great White helps create a more biologically active environment around the roots. This can be especially useful when you want to get the most from your feeding programme without overcomplicating your routine.
- ✔ Supports root-zone colonisation with beneficial microbes
- ✔ Helps improve nutrient transport and uptake
- ✔ Suitable for use alongside regular feeding programmes
- ✔ Designed for use at low concentrations
📦 Available Options and Sizes
This variable product is available in the following size options:
- ✔ 1oz
- ✔ 4oz
The 1oz option is well suited to smaller grows, propagation work or first-time use. The 4oz option is a practical choice for growers treating larger volumes of media, running regular applications or maintaining multiple plants and systems.
Features and Practical Advantages
Great White is fully water soluble, making it straightforward to mix and apply around the root zone. Its broad microbial profile makes it a versatile option for growers who want more than a single-strain product and prefer a convenient addition to an established watering or feeding routine.
