Amino acids and vitamins are non-nutrient plant additives that contain the building blocks for plant proteins and a wide spectrum of vitamins and minerals to promote plant growth. These can be applied as foliar sprays or soil drenches. By giving plants the amino acids that they are …already naturally producing, more energy is freed up to be used elsewhere in the plant. Vitamins additionally go a long way in creating a generally healthier plant by providing micronutrients and minerals that may be hard to find in potting soils.
