True organics = do no harm, build humus, use omri listed amendments.
Basically organics is a stepping stone from chemical ag into something less benign. Using OMRI and certified organic ingredients will address the physical nutrition of the soil but nature has many more secrets. It is easy to go beyond organic and way beyond organic but that involves lots of digging (for the truth) and a major shift in our understanding of how nature truly works.
You are preaching to the pastor. The secrets of nature and history reveal that "green manure" is superior to animal poop in terms of sustainability and building a long lasting society. The Incas built a society and guano, and are long gone. The Chinese have been using green manure for thousands of years, many do to this day. This isn't a direct correlation, but you know what I am saying. Passing vegetable matter through the gut of mammals is not efficient. You can ferment common wild or farmed plants and feed them directly to your plants.
Indoor growing is not the same as outdoor. For starters, we pay more to grow, and have to maximize our space. So we start using soilless organic media (peats, coco, and barks). This lets us take advantage of the accelerated wet/dry cycles of soilless organic media, which lets us push CO2, temps, and light levels. We leave true soil behind, and begin hybrid growing, a combo of soilless and soil techniques. This is usually peat or coco based media (fox farm, happy frog, roots ect). Peat is extremely good for hosting microbes, and contains nutrients. We also add nutrients via fertigation solutions.
Your attempt to define "organic" as "true soil organic" is more appropriate for subcool's subforum. Check him out, he is more your speed. Peace.
