pH levels and why they are so important is mainly due to different plants absorbing certain nutrients at different pH ranges, with some preferring a slightly acidic environment at the roots, others may prefer more alkaline conditions.

By maintaining an appropriate pH…

  • plants are less likely to suffer leaf problems or nutrient deficiencies
  • without nutrient problems, plants can grow faster and produce bigger yields
  • growers are alerted to possible issues before they become a problem, you can adjust the pH before your plants start suffering from deficiencies

Ph up and down are available separately or in kits, but before you start adjusting your pH it becomes vital to check and know what your current pH is using an accurate pH tester or meter.
