On a first run in virgin soil, yes you definitely get much larger yields. But you also get a chemmy sauce of a product. Hydro is not an option. Those days are long gone. I run Living Organic Soil, and my SoG is in recycled LOS. First run will be a little weak on yields for sure. But this is a NO TILL system, which does yield just as well as hydro from second run onwards. We have technologies and techniques available to us as organic growers that hydro can never have, like live enzymes, ACT, SST, and bringing a plant to full genetic potential with no risk of genetic drift. Hydro is history... no bottles or synthetics needed... ever...
