Flairform - pH Up 250ml

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.
  • Available in 250ml, 1L, 5L & 20L
  • Technical: Click here to view product labels, feed charts, brochures and MSDS

*Non “Dangerous Goods” (Not subject to ADR/IATA/IMDG codes)


When to Use:
Raising nutrient pH
Hydro / Coco / Soil
Bottle Sizes:
250ml, 1L, 5L & 20L


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.
