VonforneHere in Germany I can go to the garden store and buy dried, rolled Nettles. Cost about 2 €. It looks like Alfalfa.
Under ingredients, it states the ingredients, chemical identity and proportions are a trade secret, LOL. They don't want anyone to know how easy and cheap it is to make probably.
Here's a link to the MSDS for BioThrive Bloom, haven't found any of the others yet, and this is one from 2009 (assuming that's when GH started this line?)
