Correct pH is a critical but often overlooked aspect when growing in hydroponics, coco coir, or Sunshine/Pro Mix.
Put simply, the pH of your fertilizer determines how much of the mineral elements are available and accessible for the plants.
Acid loving plants like rhododendrons and hydrangeas require lower pH. Tomatoes require slightly acid conditions, while peonies and sunflowers love lime, which ‘sweetens’ the soil, or raises the pH.
There are a variety of ways to test for pH in your growing medium. pH test strips or electronic equipment are easily available. Or, collect a cup of soil from your area of concern, mix it with 2 cups of distilled water, and bring that in to our shop, and we’d be happy to test it for you.
