Organic base nutrients are an excellent way to feed your garden with clean, natural inputs and take advantage of growing organically. Unlike synthetic nutrients, which use mineral salts to create NPK blends, organic nutrients use natural substances like kelp, guano, alfalfa, worm …castings, and other common organic supplements to create powerful plant feeds. Organic nutrients tend to be more viscous than synthetics and will occasionally come with a strong odor to them. Additionally, organics can contain active biology (again, smelly) which work especially well in soil. In the same way, because organics are more viscous and contain particles of organic matter, it is more difficult to use in hydroponic systems with small feed likes or pumps like ebb and flow or drip.
