Base nutrient

A base nutrient is the foundation of plant nutrition. It contains the bare minimum essential elements your crops need to grow: macronutrients and micronutrients in the right amounts for both the vegetative phase and the flowering phase. Emerald Harvest offers both a 2-part base nutrient and a 3-part base nutrient.


Carbohydrates (a.k.a. “sugars”) are an important source of fuel for hydroponic crops. Carbohydrates feed the beneficial microbes in the root zone. Some carbs are also taken up by the plant through the roots. Growers use carbohydrate supplements to give their plants more energy during budding and flowering.


The essential elements (also called essential plant nutrients) are those that your plants require in order to grow. The three primary macronutrients are nitrogen, phosphorus and potassium. The three secondary macronutrients are calcium, sulfur and magnesium. Your plants need larger amounts of these nutrients than they need of micronutrients.

Nutrient supplement

A nutrient supplement is used as an add-on to a base nutrient. Nutrient supplements can boost yields, strengthen plants and correct nutritional deficiencies. They cannot be used alone to produce a healthy crop, but their addition to a base nutrient series brings many benefits to the plants.
