If you have a crop 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, it will lower the Ph of many liters of water with a few ml, unlike the other Ph Down on the market. It is capable of lowering the pH of a 5L jug with drops, with irrigation of less water such as liter and a half bottles is not recommended, since it will be difficult for you to get it right without going over the level, although it is not impossible.

The recommended pH levels for our plant to assimilate the maximum range of nutrients are between 5.5 and 6.8. Above these values, your plants have problems assimilating macro-nutrients such as nitrogen, phosphorus or potassium. On the contrary, when the pH drops below 5.5 we will have problems for our plants to absorb 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 them is enough.

Dosage and directions for use of Ph Down by Growth Technology:
Add all the fertilizers and supplements to the irrigation water.
Measure the acidity level 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 acidity level.

Composition of ph Down from Growth Technology:
81% Phosphoric acid.
