I found this website claiming to have a product used by large companies, including Dole, called Great Big Plants. It's suppose to be top of the line food. It's a liquid. website is greatbigplants.com I almost went for it but wasn't sure. What do you think about it
It looks to me as though they are selling what is commonly called manure tea which is (or can be) a concentrated liquid which is made from soaking manure in water then draining off the liquid, leaving the solids (fiber and such) behind. Check on the internet for 'recipes' for manure tea. It would be cheaper to make your own :o)
but have you heard of this product as being any good. I do have compost used it and it didn't seem to do much better. I don't have a way to get manure since I live in the city. The bagged compost was the best
