Know before you buy
Great White is a microbial inoculant, not a traditional fertilizer. It introduces beneficial fungi and bacteria to the root zone to improve nutrient uptake and soil health, rather than simply providing raw nutrients.
Yes, it is formulated for a wide range of plants, including vegetables and flowers. Because it is a natural, concentrated blend, it works effectively across various soil-based growing environments.
As a water-soluble powder, it is designed for easy application via soil drench or injection. Simply mix the powder with water according to the instructions and apply it directly to the root zone to ensure the microbes make contact with the roots.
Absolutely. Great White is specifically designed to improve transplant success by promoting rapid root development and reducing the stress plants typically experience when moved to new soil.
Great White provides a continuous feed effect, but it is best used during the initial planting phase and periodically throughout the growth cycle to maintain a healthy microbial population in the soil.
It performs best in soil-based media where the fungi and bacteria can colonize the root system. While it improves soil structure, it is not intended for hydroponic systems that lack a root-supporting medium.
