The invention discloses a nutrient solution formula for inhibiting green algae, comprising a basic nutrient solution and an algae inhibitory substance, wherein the basic nutrient solution comprises major elements, minor elements and trace elements. The specific ratio is: 1000 mg/L of calcium nitrate, 1000 mg/L of potassium nitrate, 200 mg/L of EDTA-FeNa, 200 mg/L of potassium dihydrogen phosphate, 150 mg/L of ammonium dihydrogen phosphate, 700 mg/L of magnesium sulfate, 7 mg/L of boric acid, 5 mg/L of manganese sulfate, 15 mg/L of ferrous sulfate, 0.25 mg/L of copper sulfate, 0.22 mg/L of zinc sulfate, 0.02 mg/L of ammonium molybdate, and 0.01 mg/L of benzalkonium chloride. The benzalkonium chloride can provide Cl ions, and it has a good bactericidal and algae-killing ability in different pH value ranges; the optimal dosage is 0.01 mg/L.

A composition for a plant growth additive that stimulates growth and promotes maximum nutrient absorption. The composition includes a quantity of vitamin B1, a quantity of vitamin B2, a quantity of vitamin C, a quantity of citric acid, a quantity of boron, a quantity of molybdenum, a quantity of potassium, and a quantity of hydrated silica that are homogeneously mixed into a growth-stimulant composition. The composition may be mixed with at least one supplemental growth ingredient such as a quantity of beeswax extract. In order to for the growth-stimulant composition to be safer when applied to a plant, a nutrient solution may further include a quantity of solute and a quantity of solvent, with the growth-stimulant composition as the quantity of solute and a quantity of water as the quantity of solvent. The composition may further be mixed with at least one macro-nutrient ingredient and at least one pH-adjusting ingredient.
