Omri isn’t perfect but it’s far from a scam…… All of the organic farmers I know aren’t going through all of the extra work of soil fertility, and tough IPM because they want a “seal” to sell their products for slightly more. They do it because they believe it produces a healthier product for people. And in order for people who want that product to even know it is grown organically, they are required to get certified. While not every allowed input and methodology makes perfect sense in organics, the main idea is people trying to do better.
Also to be clear I’m not nocking hydro or salts. Just adding my perspective.
