KEEP IT IN THE SWEET SPOT

pH Up + pH Down

pH Up and pH Down

Keep the nutrient solution and the growing medium in the “sweet spot” (pH 5.5‒6.5) for optimal nutrient uptake and no nutrient deficiencies.

What makes it work?

pH Up and pH Down are buffers composed of a weak base (up) and weak acid (down) designed to correct pH imbalances in hydroponic gardens.

  • pH Up when the pH tests too acidic
  • pH Down when the pH tests too alkaline
  • Small, root-and-substrate-friendly quantities

Why Use It?

pH Up and pH Down regulate the pH for optimal nutrient uptake and stable beneficial bacteria colonies, and they forestall nutrient deficiencies.

Things to Note

  • Emerald Harvest professional base nutrients and supplements are pH buffered, so if you’re using our full product line as directed, your garden should already have a balanced pH.
  • When the pH of the nutrient solution is too low or too high, certain elements (e.g., iron or manganese) could be wholly or partially “locked out.”
  • The sweet spot, pH 5.8–6.3, is the ideal pH range for high-value plants grown in hydroponic gardens.

Preempt lockout

Avoid nutrients deficiencies by keeping the pH stable.

Increase uptake

In the pH sweet spot, all essential elements remain available.

Safeguard your plants

Imbalanced pH can damage—or even kill—your plants.

It performs great and is easy to use.

Your line was sold to me really well by one of your folks; it performs great and is easy to use. It makes some monster autos and I’m thrilled with what the King Kola does for some of these dense strains. Cheers, I thank you for the hard work!

Pretty amazing.

Pretty amazing, results were considerably noticeable and the quality was top notch. King Kola, Emerald Goddess, Honey Chome, Micro, and Sturdy Stalk are all great! Thanks again for a great product.
