its there manure based compost in a "tea bag"
Ingredients: Dairy cow manure, straw, vineyard wood chips, and biodynamic concentrations of yarrow, chamomile, valerian, stinging nettle, dandelion, and oak bark.
always to much money for me to try (I can get most of the ingredients for free around me). after all its literally just the poop and bedding they clean out of dairy stalls, then they add wood chips, bark, and "weeds", they are actually dynamic accumulators but are often treated as unwanted weeds. the microbes are found in any organic well composted compost.
that being said it doesn't look bad just gimmicky. give a try, your plants will probably enjoy it. be sure to add the bag contents to your compost or soil after you're done. or just buy a big bag of there compost and make/use your own tea bag. same-same
