For many, organic gardening means growing plants in soil with the presence of water and light and application of organic fertilizers. But many are misled by what most companies call "organic fertilizers" which are not really organic. In most cases, you'd want to see an "OMR" certification on a product and know how easily they flow through your hydroponics system. There are plusses and minuses for organic/natural gardening and you can definitely find organic/natural fertilizers that'll work for your garden. Organic fertilizers are not chelated (bound to special substances) so they might take a longer absorption time in plants as compared to chelated synthetic fertilizers. Grandmasters recommend the combination of organic/natural base hydroponics fertilizer with synthetic bloom boosters additive to boost growth rate. The key to finding a good organic/natural hydroponic fertilizer is to ask your hydroponics store staff and manufacturers about the product quality.
