Most growers recommend a pH range between 5.5 and 6.2 for optimal growth within a hydroponics system. Yet achieving that level can be challenging, particularly when the amount of minerals in your growing solution is unregulated.

This single concentrated formula Potassium Hydroxide 45% utilizes pure potassium hydroxide in solution to deliver a high level of alkaline buffering power needed for consistent pH levels without the use of acids!

Our product enables easier absorption of nutrients through the soil, clay, or liquid medium by increasing the pH level. pH Up is an ideal product for promoting healthy plant growth and can be used in conjunction with almost any nutrient.

Frequently Asked Questions

What can I use pH up for?

You can use pH Up for almost any application that requires a controlled alkaline solution. Hydroponic gardeners of all experience levels commonly use it for many different needs. pH up is also used as a foliar spray that helps enhance the health and growth of plants.

What is the use of pH up solution in hydroponics?

pH Up helps to increase the pH in Hydroponic solutions. Sometimes when you perform a transplant to soil or when you are growing in an organic medium, the pH may drop to much lower levels; this pH up can bring your levels back to optimal levels. So you can use pH up in soil, coco coir, rockwool, clay pebbles, perlite, and vermiculite.

Can I add pH down after pH up?

Yes, you can add pH down after pH up or vice versa — however, it’s best to keep a difference of a few hours between applications of both solutions.
