Aptus K-Boost K-Boost is an organo-mineral maturation booster combining L-amino acids with potassium (K) and sulfur trioxide (SO₃). It supports the maturation process, enhances yield, and improves the final quality of crops. Why Choose K-Boost? Promotes fruit and bud maturation Enhances crop quality 100% water-soluble, leaving no residue Highly bioavailable nutrients Produces firm and high-quality end products How to Use K-Boost Apply from the 5th to the 7th week of flowering. Mix 3–5 ml per 10 L of water. Shake well before use. Fully water-soluble and leaves no residues in irrigation systems. Key Ingredients Organic nitrogen (N) Potassium (K) Sulfur trioxide (SO₃) L-amino acids How K-Boost Works Organic nitrogen, potassium, and L-amino acids synergistically enhance plant maturation. Potassium regulates water management (osmoregulation) in plants, ensuring proper stomatal function and reducing water loss. Potassium supports starch and protein synthesis while regulating enzyme activity. Sulfur aids the maturation process and contributes to weight gain. L-amino acids organically chelate nutrients for improved bioavailability. Tips for Optimal Results Use K-Boost during the last four weeks to achieve compact, firm end products. Combine with CaMg-Boost to maximize weight, firmness, and prevent nutrient antagonism between potassium (K) and magnesium (Mg).
