Most of the common plant "microbe products" have no where near the claimed bacteria counts. The State of Oregon is the only place I know of that has trustworthy 3rd part test results for a sampling rhizobacteria products every year, so if you want a product that actually contains a useful amount of bacteria, check their results. At least half of the most popular microbe products had zero viable organisms-this is one of the biggest areas of active fraud in the cannabis grow industry. I use Tribus based on those test results, one year the Tribus sample they tested had a higher count of viable organisms than every single other sample combined. Mycorrhizae products are more reliable since new labeling standards took effect for them in 2020, but it's important to compare the cfu/g. The fraud in Mycorrhizae comes from the use of tons of filler and very low cfu/g, as well as stuffing products with ecto mycorrhizae when our plants can't use it.
