You should get an instagram and hit up some companies for free samples. I just got a free bottle of worm casing tea! My compost is almost complete though. I made some tea and used on my outside garden, and they are not dead, soooooo, when in rome. Dont know if that applies to this convo, but yeah lots of free stuff to be had! Even in nature. DO you have access to Stinging Nettle? That stuff is supposed to be like the best.
