Description

Bring a low reservoir back into the uptake window

A concentrated pH adjuster in a 0.95 litre bottle, formulated on potassium hydroxide to lift the pH of a nutrient solution that has drifted too acidic. Because it is concentrated, a small volume moves a full reservoir, which makes fine adjustment straightforward once you learn how your water responds. The potassium base means the correction adds an element the plant already uses rather than something inert. It suits soil, coco and hydroponic systems alike and belongs in any grow room where feed is mixed by hand.

Key Benefits

  • Accurate correction - Concentrated formula lets you creep up on your target rather than overshoot.
  • Potassium hydroxide base - Adjusts pH using an element that plants already take up.
  • Economical in use - Small doses move large volumes, so a bottle lasts.
  • Works in any medium - Suitable for soil, coco and hydroponic reservoirs.
  • Protects uptake - Keeps the solution in the range where nutrients stay available.

The Cost of a Nutrient Solution That Drifts Acidic

Nutrient availability is governed by pH, not by how much you put in the tank. Let a reservoir slide down past the usable band and iron, manganese and zinc become over-available while calcium and magnesium lock away. What you see is interveinal yellowing and slow growth on plants that are, on paper, fully fed. Correcting upwards restores the chemistry so the feed you paid for actually reaches the root.

How to Use

  • Mix and stir your full nutrient solution before touching the pH.
  • Add pH Up a few millilitres at a time, stirring between additions.
  • Allow the solution to settle, then re-test with a calibrated meter.
  • Repeat in small steps until you hit your target for the medium.
  • Wear gloves and eye protection, and store the bottle sealed and upright.
