Growth Technology GT pH Drop - pH Down Solution 250mL

Maintain the ideal pH for healthier, more productive plants with GT pH Drop, a fast-acting pH Down solution designed to safely and accurately lower the pH of nutrient solutions, reservoirs and irrigation water. Suitable for hydroponics, soil, coco coir, propagation and tissue culture, GT pH Drop helps create the optimal pH range for maximum nutrient availability and vigorous plant growth.

Formulated with citric acid, GT pH Drop provides a plant-friendly alternative to harsh acid-based pH reducers while delivering fast, reliable pH adjustment. It is also classified as Non-Dangerous Goods, making it easy to store, handle and ship Australia-wide.

Why Use GT pH Drop?

The pH of your nutrient solution has a major impact on nutrient availability. When the pH is too high, plants can struggle to absorb essential nutrients such as iron, calcium, magnesium and phosphorus, even when they are present in the solution. This can lead to nutrient deficiencies, reduced growth and poor plant performance.

GT pH Drop allows you to make precise pH adjustments, helping maintain the ideal growing environment so your plants can access the nutrients they need for healthy development.

Features & Benefits

• Quickly and reliably lowers the pH of nutrient solutions and irrigation water

• Helps maximise the availability of essential nutrients

• Suitable for hydroponics, soil, coco coir, propagation and tissue culture

• Citric acid formula provides a safer, plant-friendly alternative to harsh acid-based pH reducers

• Easy drop-by-drop dosing for precise pH adjustment

• Non-Dangerous Goods classification for simple storage and Australia-wide shipping

• Suitable for both home gardeners and commercial growers

How to Use

1. Add all nutrients and additives to your water and mix thoroughly.

2. Allow the solution to settle before testing the pH.

3. Add GT pH Drop one drop at a time, mixing well after each addition.

4. Re-test the pH after every addition until the desired level is reached.

For most hydroponic nutrient solutions, a pH between 5.5 and 6.5 provides the best nutrient availability, although the ideal range will vary depending on the plant species.

Tip: Record how many drops are required per litre to make future pH adjustments quicker and more consistent.
