Turn it up. Bring predictability and consistency to your grow with our premium pH Up formulation. Bloom City’s pH Up formulation contains a strong and stable base complex. pH Up increases feed water pH to keep root systems and soil balanced. Formulated for use in hydroponic gardens as well as soil gardens. Add pH Up to every watering and aim for a pH of 5.8 to 6.2 for healthy and robust plant growth. Bloom City is better because other pH adjusting brands use low grade industrial chemicals, which are not designed for plants. Bloom City’s pH Up is strong and stable, which means your feed water will hold pH all the way into the root zone. Made in America from the highest quality sources by a small team of passionate plant scientists.
