I remember there being a big push for using compost tea, using various ingredients, such as compost, manure, guano, castings and microorganisms mixing it all together and letting it steep while stirring allowing the bacteria and other organisms multiple. I've seen articles online about a gardener up in Alaska, how grows very large vegetables because he uses his compost tea. At the time there were ads for a small home compost tea maker and I even bought some at a local garden center here, but it isn't available any more. I couldn't tell if it helped or not. Being down in Florida and growing heliconias, I'm not even sure you could see a difference, since they do grow quickly and multiply even faster. I think you'd have to do a comparison with two small plants. One using only compost tea and one using only the normal fertilizer. It's something to think about or even beans since they grow very quickly.
So that's my thoughts on that so far.
