## Description

Bloom City’s pH Up + Down formulations 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. Add to every watering as appropriate and aim for a pH of 5.8 to 6.2 for healthy and robust plant growth in soil, and aof 5.5 to 5.7 for hydro or aeroponic gardens. Other pH adjusting brands use low grade industrial chemicals, which are not designed for plants and break down in watering reservoirs. Bloom City’s pH adjusters are strong and stable, which means your feed water will hold pH all the way into the root zone. Bring more predictability and consistency to your grow with our premium pH adjusting formulations. Bloom City nutrient systems are an ultra-premium line designed for the craft grower. Our nutrients and supplements are simple to use and produce amazing results. Leave behind the confusing and dirty world of Big-Ag fertilizers and upgrade to Bloom City. Bloom City’s products are made in America from the highest quality sources by a small team of passionate plant scientists. All our ingredients are better for plants, better for you, and better for the planet. Bloom City is simply the best choice for the conscientious grower.
