INCREASES CROP YIELD & QUALITY: Amino acids that contribute to their faster and more efficient absorption of nutrients by the plant. It improves the taste of fruits and vegetables, increases yields, and improves quality. INCREASES PLANT IMMUNITY: Stress such as high temperature, low humidity, frost, pest attack, and floods have a negative effect on plant metabolism with a corresponding reduction in plant quality. The application of amino acids before, during, and after the stress, conditions supplies the plants with amino acids which are directly related to stress physiology and thus has a preventing and recovering effect. DIRECTION FOR USE: Use Extra as an additive supplement or as a foliar spray. For Light Feeding, Add 1ml / 1L & for Heavy Feeding, Add 2ml / 1L to your nutrient solution. Reduce nutrient strength if plants show signs of stress, or if growing in very bright, hot or dry environments.
