MycoGrow™ Soluble is similar to Plant Success™ Tabs but is more concentrated, containing more spores and more species, plus other beneficial organisms. Consisting of powdered spore mass rather than tablets, MycoGrow™ Soluble is great for adding to rooting media or commercial potting soils. Sold in one ounce increments. An ounce is sufficient to treat 125–250 plants covering approximately 250 square feet.

Note: cannot be shipped to Hawaii.
