pH, EC & Water Quality Management

Australian Tap Water for Hydroponics: Melbourne, Sydney, Brisbane, Perth and Adelaide
Every litre of nutrient solution you mix starts with your tap water. The pH, mineral content, and chemical treatment of that water directly affect how your nutrients behave, how stable your reservoir stays, and how much buffering work you need to do throughout the grow. Australian tap water varies significantly by city — and in some cities, by suburb. Understanding what comes out of your tap is one of the most practical things a grower can do, and it costs nothing to check. Why Tap Water Quality Matters in Hydroponics... Read more...
What EC Should I Run? A Complete Guide for Australian Hydroponic Growers
EC is one of the two numbers that every hydroponic grower needs to get right. Get it wrong and nothing else in your program compensates for it. Too low and plants are underfed and slow. Too high and roots stress, uptake locks out, and plants show symptoms that look like deficiencies even though the reservoir is full of nutrients. This guide covers what EC measures, the target ranges for different crops and growth stages, and how to adjust for Australian water quality and growing conditions. What EC Actually Measures EC...

Why Does My pH Keep Dropping in Hydroponics? Causes and Fixes for Australian Growers
Most hydroponic growers experience pH drift at some point. But when pH keeps dropping consistently — not just drifting — something specific is causing it. Chasing pH up with corrections every day without understanding the root cause is one of the most common and frustrating cycles in indoor growing. This guide explains exactly why pH drops in hydroponic systems, what each cause looks like, and how to stabilise your reservoir for good. What a Dropping pH Actually Means pH measures the acidity of your nutrient solution. In hydroponics, the target... Read more...
Understanding pH and EC in Hydroponics: A Practical Guide for Australian Growers
pH and EC are the two most important numbers in hydroponics. Get them right and plants thrive. Get them wrong and no amount of expensive nutrients or lighting will save your crop. This guide explains what pH and EC mean, why they matter, how to measure them accurately, and how to keep them in the right range. What pH is in hydroponics pH measures how acidic or alkaline your nutrient solution is on a scale of 0 to 14. A pH of 7 is neutral, below 7 is acidic, and... Read more...
Hydrogen Peroxide and Hydrochloric Acid in Hydroponics: When to Use Each
Hydrogen peroxide and hydrochloric acid are both used in hydroponic systems, but for very different purposes. This guide explains when to use each, the risks involved, and how to handle them safely in your grow room. Read more...
