Hesi pH Up Grow

Hesi PH UP. Hesi pH Up contains 50% Potassium hydroxide. Raises the pH. Use during growth and flowering.. Hesi pH Corrector pH Minus Growth, and pH Plus corrects the pH value of food solutions for plants on hydro and coco.. Hesi pH UP is a pH corrector / raiser for hydroponics and coconut fiber cultures. Hesi pH UP is essential for these kind of cultivation cause the nutrient solution water needs a certain pH value around 6 (5.8-6.2) and if the pH decreases the roots could be seriously damaged. The nutrient solution water in these kind of crops runs along the roots and must contain all the substances in the appropriate concentration for the plants, therefore the pH level must be optimal at the time of irrigation so that the plant can absorb all nutrients and grow strong and lush.
