Think of it this way.. Bottles nutes are like having your plants hooked to an IV.. They feed your plant directly, bypassing the job of microorganisms. Microorganisms feed the soil, and make it nutrient rich.. They feed on organic matter and turn that in nutrients for the plant. The plant will then feed on those nutrients as needed (not forced like with bottled nutes).. One cubic inch of healthy soil will have billions of microbes in it. As an organic grower, my job is to simply feed the microbes and keep them alive. In turn, they will feed the soil, which will in turn, feed the plant. It may seem complicated, but once you understand the basics of the food chain, it gets easier.
