Your pH control freak. Bring predictability and consistency to your grow with our premium pH formulation. Bloom City’s pH Up + Down contain strong and stable acid + base complexes. Increase or decrease feed water pH to keep root systems and soil balanced.

• Formulated for use in hydroponic gardens as well as soil gardens.
• Adjust pH with 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 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.
