GT pH Down and pH Up

PRODUCT DETAILS

The pH levels in all hydroponics systems need to be carefully monitored and controlled. This also applies when using soil or coco coir as your medium - although both mediums are more forgiving than growing hydroponically, getting it right could mean the difference between average or bumper, maximised yields come harvest time.

The ideal pH range of nutrient solutions in a hydroponic set-up should be somewhere between 5.6 and 6.2. In soil this optimal range is around 5.8-6.5, and in coco coir you're looking for somewhere in between 5.5-6.5, with an overall average of around 5.9 throughout the grow cycle. pH levels can easily be controlled with the help of either a pH up or pH down solution.

If your pH levels are outside the recommended range then your system is at a high risk of causing harm to your plants. At the very best the performance of your plants will suffer and at worst your plants will die, especially if they are left outside the optimum range for too long.

Both pH Up and pH Down are highly concentrated aggressive liquids and should be handled with extreme care. Please wear gloves and eye protection!

pH Down:

This pH Down solution contains phosphoric acid which will quickly and effectively act to reduce the pH of your nutrient solution. The formula was recently diluted to the maximum strength legally allowed, which is 30% concentration.

pH Up:

This pH Up solution contains potassium hydroxide at a concentration of 25%, which is again stronger than most other pH Up solutions on the market. This formula will act quickly to raise the pH of your nutrient solution back to an optimum level.

 

***Health and safety***

These solutions are highly concentrated aggressive liquids and the manufacturer recommends exercising the following precautions:

  • Wear gloves and eye protection when handling and administering
  • Store safely and keep out of reach of children

Available in 250ml, 1l and 5l sizes.
