How is Bio · pH + used? Mix the necessary Biobizz nutrients and measure the pH of the mixture. Add 0.1 ml Bio · pH + to increase the pH by 0.1 points. Add the required amount of Bio · pH +, stir for 10 seconds and measure the pH again. Add Bio · pH + until the optimal pH range of 6.2-6.5 is reached, and the nutrient mixture can be added to the plants. Why Bio · pH +? Bio · pH + can be used both during the growing and flowering periods, in any irrigation, and in combination with any Biobizz substrate or liquid product. Bio · pH + contains no strong acids. This means that this 100% biological pH regulator does not affect the micro-life in the substrate. So your culture stays organic, from seed to harvest!
