If you have a culture in which you spend many liters of water or a hydro or Aero table, the Ph Down regulator is your liquid to lower the Ph. Being concentrated and having an 80% acid ratio, the pH will drop many liters of water with few ml, unlike the other Ph Down in the market. It is capable of lowering with drops the pH of a 5L carafe, with less water irrigations as liter and a half bottles is not recommended, as it will be difficult to get it right without going over the level, although it is not impossible.
The recommended pH levels for our plant assimilate the maximum range of nutrients are between 5.5 and 6.8. Above these values your plants have problems to assimilate macro-nutrients such as nitrogen, phosphorus or potassium. On the other hand, when the pH drops below 5.5, we will have problems for our plants to absorb the micro-nutrients, such as copper, iron or manganese.
Do not forget that it is an acid, and that you should not touch it with your hands, although washing it is enough.
Dosage and way of employment of Ph Down of Growth Technology:
Add all the fertilizers and supplements to the irrigation water.
Measure the level of acidity with a reagent or digital meter.
If the level is higher than 6.5 we will have to add a drop of Ph Down (one milliliter in tanks with more than 50 liters).
We will measure again, and repeat the steps if necessary until we achieve the desired level of acidity.
Composition of ph Down by Growth Technology:
81% Phosphoric acid.
