Whether you're growing plants hydroponically or just in regular soil, the pH of the growing medium around your plants is important for ideal growth. The pH of your growing medium can be acidic, basic or alkaline, or neutral; generally, plants do best with a pH of about 5.5 to 6.5. Below that, plants are acidic, and above that, they're basic or alkaline. If you've discovered that the pH of your growing medium is out , you can use a number of different ways to fix the problem.

Firstly, you need to:
  1. Add the nutrients or fertilizers that you're currently using for your garden. If you're growing hydroponically, wait about one hour before you move on to the next step. If you're growing in soil, wait about 24 hours.

  2. Test the growing medium by inserting a pH test strip or electronic test kit into it, following the instructions on the test kit to ensure proper testing. Read your pH level and compare that to the ideal pH for the type of plant you're growing to determine whether you need to raise or lower the pH of the growing medium.

How to use:

  1. Fill a jug with clean water. Be sure to read the instructions on the proper water-to-substance mix.

  2. Add pH up to raise your pH. 

  3. Water your plants with the solution. If you're growing in soil or another solid such as perlite, water the plants with the solution in the same way you would water the plants with regular water. If you're growing hydroponically, add the solution to your hydroponic solution.

  4. Test the pH again following the treatment, to determine whether you need to do another treatment. For hydroponics, wait about 30 minutes to test the pH again. For soil and other solids, wait about 24 hours.
