Flairform pH Test Kit - pH Up & Down - For Hydroponics (250mL)

Introducing Flairform pH Test Kit - pH Up & Down - For Hydroponics

The working nutrient pH should be checked at the following times:

1. When first made.

2. After the addition of top-up water or additives - especially if either is highly alkaline.

3. In recirculating systems, pH should be checked on a daily basis because the uptake of water and nutrients causes pH to change.

NOTE: It is best to adopt a pH maintenance regime that helps prevent pH from getting too high.

If pH is left too high for a long period of time, the resultant precipitate is usually not easily re-dissolved.

If your pH tends to continuously rise (the most common trend), then at each adjustment, reduce the pH to about 5.0 using pH Down.

This will give you a much larger pH "safety" margin than, for example, 5.8.

Flairform pH Up - 

Flairform pH Up is non-corrosive (non HazMat*).  This solves the long-standing safety and handling problems associated with regular pH Up solutions:

• Concentrated (600g/L potassium carbonate): This provides the equivalent working strength of 400g/L potassium hydroxide.
• Much safer to use than potassium hydroxide and more environmentally friendly.
• Ideal for mail order and distribution: No special freight, handling or storage requirements.
• Non Dangerous goods (Not subject to ADR/IATA/IMDG codes)

When to use - Raising nutrient pH

Substrates - Hydro / Coco / Soil

Flairform pH Down -

Flairform pH Down is non-corrosive (non HazMat*).  This solves the long-standing safety and handling problems associated with regular pH Down solutions:

• Organic formulation (500g/L citric acid).
• Much safer to use than phosphoric or nitric acid and more environmentally friendly.
• Ideal for mail order and distribution: No special freight, handling or storage requirements.
• Non dangerous goods  (Not subject to ADR/IATA/IMDG codes)

When to Use - Lowering nutrient pH

Substrates - Hydro / Coco / Soil
