pH DROP
Precisely lower the pH of your water and nutrient solutions.
GT pH DROP is a citric acid-based solution that quickly and safely lowers the pH of water and nutrient solutions. Suitable for hydroponics, soil, coco coir and propagation.
Benefits
pH CONTROL FOR HEALTHIER PLANTS
Quickly and reliably lowers pH in nutrient solutions, reservoirs, and irrigation water.
Correct pH supports the availability of iron, calcium, magnesium, phosphorus, and essential trace elements, helping plants access the nutrition they need to thrive.
The citric acid formula is plant-friendly and safe for routine use across all growing systems.
Non-dangerous goods classification makes it safe and simple to store, handle, and ship Australia-wide.
Guide
Add all nutrients and additives to a container as directed. Mix well and allow the solution to settle before testing the pH. The ideal range is 5.5–6.5 depending on your plant species.
Add pH DROP one drop at a time to the solution, testing the pH after each addition and noting the number of drops used for future reference. Repeat until desired pH is reached. Use solution promptly to optimise pH and maximise results.

Frequently Asked Questions
What is the ideal pH range for my nutrient solution?
For most growing systems, a pH between 5.5 and 6.5 is recommended. Regular monitoring helps ensure plants can consistently access the nutrients available to them and maintain healthy growth.
Can I use GT pH Drop across different growing systems?
Yes. GT pH Drop is suitable for hydroponics, soil, coco coir, propagation systems, and tissue culture acclimatisation. It is designed for both hobby and commercial growers.
How much GT pH Drop should I use?
Add GT pH Drop gradually using a dropper, mix well, and re-test before adding more. The amount needed will vary depending on your water source and starting pH. Recording the number of drops used per litre is a good habit and will make future adjustments quicker and more consistent.
How do I know if my pH is too high?
If your pH is too high, plants may struggle to access key nutrients including iron, calcium, magnesium, and phosphorus. This can show up as yellowing leaves, slow growth, or signs of nutrient deficiency even when nutrients are present in the solution.
What is GT pH Drop made from?
GT pH Drop is a citric acid based solution. Unlike many harsh acid based pH reducers, it offers a safer, more grower-friendly formula suitable for routine use across all growing systems.
