Description
Great White is the market’s most cutting-edge premium mycorrhizae formula. This highly concentrated and diverse blend of beneficial microbes will help boost your plants’ root systems, leading to greater water retention and nutrient uptake.
Mycorrhizae form a type of symbiotic relationship between fungi and plant roots. The fungi colonize the roots and form a network of filaments called mycelium. In exchange for sugars produced by the plant, the mycorrhizae help to increase the surface area of the roots, improve water and nutrient uptake, and protect the roots from pathogens.
For gardeners, this symbiotic relationship can be beneficial in several ways. First, it can help to improve the health of plants by providing them with additional nutrients and water. Second, it can help to reduce the need for chemical fertilizers and pesticides. Finally, it can help to improve soil structure and increase the population of beneficial microorganisms. Consequently, mycorrhizae play an important role in sustainable gardening practices.
How To Use
Great White can be used in all stages and all growing types. Use weekly for best results.
Seeds:Lightly dust with Great White.
Cuttings:Dip cutting into rooting gel/solution then lightly dip directly into Great White powder. Mix into pre-soak/fertilizer solution at a rate of 1 tsp or 3.3 grams per 2 gallons 7.5 litres of water.
Transplanting:Lightly dust planting hole and place plant directly on top.
Soil, Coco and Topfeeding:Apply at a rate of 1 tsp (3.3 grams per 2 gallons (9 litres) of water.
Hydroponics:Mix into reservoir with regular feeding at a rate of 1 tsp (3.3 grams) per 10 gallons (38 litres) of water.*
*Hydroponic users may find settling or particles on bottom of reservoir and should not be concerned of product loss; it’s normal for the carrying agent to settle.

Frequently Asked Questions (FAQ)
What is Great White Mycorrhizae and what does it do?
Great White is a concentrated microbial inoculant that combines mycorrhizal fungi, beneficial bacteria, and Trichoderma. It helps roots form a larger underground network to improve water and nutrient uptake, root mass, and plant resilience. The blend includes 16 mycorrhizal fungi, 14 bacterial species, and 2 Trichoderma strains to support vigorous growth across a wide range of plants.
Is Great White Mycorrhizae a fertiliser, and is it organic?
No—Great White isn’t a fertiliser in the NPK sense. It’s a microbial product that helps plants access existing nutrients more effectively. It’s widely used in organic-style gardens and aligns with biological growing practices, but always check certification rules if compliance matters to you.
What plants can benefit from Great White Mycorrhizae?
Most vegetables, herbs, flowers, fruiting plants, trees, and houseplants respond well—especially during transplanting or active growth. Brassicas (e.g., broccoli, cabbage) may see limited results due to weak mycorrhizal associations.
When is the best time to apply Great White?
Transplanting is the ideal moment—getting microbes in contact with young roots early gives the best colonisation. Many growers also reapply during early veg, after root disturbance, or when reinforcing the root zone. Results typically show within 1–3 weeks.
Can I use Great White in soil, coco, or hydroponics?
Yes—it works in all common growing media. It’s especially effective in soil and coco. In hydroponics, expect some settling in the reservoir and avoid sterile systems, which aren’t friendly to microbes. Clean lines regularly to avoid clogging.
How do I apply Great White to seeds, cuttings, and transplants?
Dust seeds, lightly dip cuttings after rooting gel, or dust the transplant hole and root zone. You can also soak propagation cubes or mix it into potting media. For existing plants, topdress and water in. Weekly use during active growth is common.
Can I use Great White in compost tea or with other biologicals?
Yes—Great White pairs well with compost teas and organic inputs like worm castings or kelp. It also works alongside most microbial and fertiliser programs, though overstacking multiple inoculants can be redundant.
Does Great White help with transplant shock or drought tolerance?
Yes—mycorrhizae are especially helpful during transplanting and for improving water access in dry spells. It can also support better nutrient cycling, which may reduce the risk of lockouts, especially when growing conditions are managed well.
Can water quality or pH affect Great White performance?
Yes—heavily chlorinated water, strong pH adjusters, peroxide, or fungicides can reduce microbial viability. Always add Great White after adjusting pH, use filtered water where possible, and avoid combining with sterilising agents unless you plan to re-inoculate.
How should I store Great White, and does it expire?
Store it cool, dry, and sealed. Avoid moisture and direct sun—humidity is the main cause of clumping and microbe loss. While it doesn’t “go off” overnight, potency drops over time if stored poorly. Always use clean, dry tools when scooping.
Quality products fast shipping and free root Roids sample, what more could you ask for?
Thanks Kevin! Quality gear, fast shipping, and a little Root Roids bonus thrown in for good measure 😎 Love hearing everything arrived quickly. Really appreciate the support mate! 🙌
I’ve sourced Perlite from a few different places. This one is by far the best quality I have come across. The service from the guys at Dr Greenthumbs is always excellent also.
Thanks Ellis! Stoked to hear the quality’s standing out from the crowd We know how hit and miss perlite can be, so that means a lot. Really appreciate the kind words about the service too legend! 🙌
Many Thanks Scott. followed your instructions and drenched the orchid roots at the concentration you recommended. Root aphids are gone and no adverse effect on the flowering orchids.
Thanks Leigh! Love hearing it did the trick and the orchids handled the treatment beautifully Nothing better than seeing those root aphids gone for good. Cheers for trusting the advice mate! 🙌
