Ph Down by Growth Technology is a Ph adjuster that contains phosphoric acid which will allow you to adjust the acidity level of your water. Your plants will be able to absorb all of the nutrients given to them; if your plants don't have the correct pH level, they won't be able to absorb certain nutrients.
If you need to use quite a lot of water or a hydro or aeroponics work station, Ph Down can be a massive help thanks to the fact that it's incredibly concentrated; it can be used to lower the pH of a large amount of water with just a few milliliters, unlike most Ph lowering products on the market. It is able to lower the pH in a 5L tank with a few drops. It is not recommended for smaller amounts - like 1.5 L bottles- since it's quite hard to dose it out.
The recommended pH level for plants to be able to properly absorb nutrients is between 5.5 and 6.8. Over these values, plants find it difficult to absorb macronutrients such as nitrogen, phosphorus or potassium. When pH dips below 5.5, your plants will have problems absorbing micronutrients such as copper, iron or manganese.
Don't forget Ph Down Ionic is an acid - you must not touch it with bare hands.
