Help Plants Absorb Nutrients Organically

Organic PH Up by Professor’s Nutrients is made for you to increase the pH of your nutrient solution.

The working range of pH for hydroponics is 5.5-6.5. However, we recommend sticking with a tighter tolerance of 5.8-6.2 pH. This is to ensure Iron (Fe) isn’t locked out when the pH climbs too high. If that happens other macronutrients such as Boron, Copper, Manganese and Zinc will not uptake either. On the other end, pH too low will lock out Calcium and Magnesium.

Organic PH Up Directions For Use

  • Scoop up a small sample of nutrient solution and test it for starting pH. Use Up or Down as required.
  • Add a tiny amount (10ml per 200L or 1 drop into watering can), mix then let settle. Test again.
  • Repeat until desired pH level
