Superior pH control for all plants in all growing mediums. Bring more predictability and consistency to your grow with our premium pH Down formulation. Bloom City’s pH Down formulation contains a strong and stable acid complex. pH Down decreases feed water pH to keep root systems and soil balanced.

• Formulated for use in hydroponic gardens as well as soil gardens.
• Add pH Down 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 Down 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.
