Grower’s Tip:
Chelates are compounds that help make a number of plant nutrients, especially micronutrients (copper, iron, etc.) available to crops. If chelates are NOT used in the nutrient solution, plants would be deprived of several micro-nutrients which can lead to deficiencies, inhibited growth and reduced plant health.
