T.A. pH Down

R220 - R11 690
INFORMATION

Description

Premium pH management and buffering for hydroponics, coco and soil.

Not just a simple acid: T.A. pH Down makes a real contribution to nutrient solution stability. To make T.A. pH Down we carefully blend three acids commonly used alone in hydroponics to give you all the benefits of each - without the disadvantages.

How T.A. pH Down works

T.A. pH down uses nitric and phosphoric acids to do the initial heavy lifting of altering your water pH, and the blend of both means no disturbance to your N/K ratios throughout grow and bloom and no residue on the surface of your tank from using phosphoric alone in hard water areas.

Then, with its own special characteristics, organic citric acid takes over to buffer pH changes over time, keeping your nutrient solution more stable, and helping handle calcium excesses in hard water areas.

Importance of pH

There is no such thing as an ideal pH. High values help cation uptake and low values help anion uptake: every fixed pH is a compromise. The usual safe range recommendation is from 5.5 to 6.5. Our advice is to stay on the low side: from 5.5 to 6.2.

Users of T.A. / General Hydroponics nutrient products generally do not experience problems maintaining the proper pH range because the formulas are pH buffered. However, some important exceptions do exist. pH can acidify to an unacceptable level when nutrient solutions are used with poor quality water, or pH unstable media, such as rockwool. High growth rates can also destabilize pH.

 

How to use

To adjust pH: Add a small amount to water or nutritive solution as required. Mix solution thoroughly. Re-test with a pH meter or good quality pH test kit.

 

Warning:

  • Only a small amount is needed as the product is very concentrated.
  • Always wear appropriate protection when handling strong acids.
