One of the most common questions we receive is whether, as the plant's life cycle progresses, we should adjust the acidity of the irrigation water up or down. The agronomic reality is that there's no fixed rule; the pH of the root zone is a living and dynamic environment that changes over time. In this video, we analyze in depth the three main factors that unbalance the pH of your substrate: • The type of irrigation water: If you use hard water with a high concentration of carbonates (as in many areas of eastern Spain), you are gradually introducing lime into the substrate. This will push the pH up, causing nutrient lockouts within a few weeks, even if your fertilization schedule is correct. To compensate, it's common to lower the initial pH slightly. • Fertilizer composition: The chemistry of your fertilizers affects pH. A nutrient rich in nitrates tends to raise the pH of the root zone. Conversely, fertilizers with excess ammonium or urea (very common in coco coir fertilizers) will eventually acidify the root zone drastically over time. • Substrate stability: Regular peat is naturally acidic and, due to its high buffering capacity, will tend to return to that initial state over time. Coco coir, however, has a natural pH of around 6 and is more stable, making it more difficult to alter its pH if you water correctly. • The key to success is not to correct blindly, but to be guided by empirical measurement. I'll explain how to measure the pH of the drainage water to know exactly what is happening in the roots and whether you need to make corrections by raising the values ​​with silica or lowering them with acids. ⏱ VIDEO CHAPTERS: 0:00 - The debate: Should you raise or lower the pH? 0:21 - Factor 1: The problem of hard water and carbonates 0:49 - Factor 2: How nitrates and ammonium alter your substrate 1:16 - Factor 3: The buffering power of peat vs. coco coir 1:41 - The professional technique: Measuring drainage water 2:06 - Recommended values ​​(6.0 - 6.5) and diagnosing problems 2:26 - Botanical Bonus: Active acidification by roots 👇 Leave your comment!
