Hesi PH + Plus PH corrector 

The Hesi PH+ corrector is the perfect ally for the grower. This product allows to raise the PH level of the water, and therefore of the soil. It is a versatile product that can be used in all the stages of the plant's life cycle, such as growth and flowering. 

The PH is a fundamental value to take into account when it comes to growing plants. No matter what stage the plants are in, an optimum PH level should be maintained, usually between 5.5 to 6.5, depending on the growing phase the plants are in. Otherwise, the plants will not be able to absorb the nutrients properly, no matter how much fertilizer we use. A wrong PH can eventually lead to more serious problems, even to fully crop loss.

However, there is no need to worry. The Hesi PH+ formula was designed to avoid salts clogging caused by wrong PH levels. In fact, the PH+ by Hesi has a Potassium Hydroxide concentration of 50%, which ensures a powerful PH correction.

The ideal complement for Hesi PH + is a PH meter. In this way, before applying any product that is going to modify the PH level, it is very important to know the levels from which we start. In this way, we will be able to work on specific results and know if there is a need for increase or decrease in the PH levels.

Hesi Ph Plus is designed for all types of growers. Its way of use, as you will see later, is very simple, so no technical knowledge is needed to apply this PH regulator to the irrigation water of any crop. No matter how little experience you have, with Hesi PH + the operation is hassle-free, which is why it is one of the most efficient PH regulators on the market.

How to know if it is the right product for a crop? very simple. Firstly, the PH of the water must be measured with a meter, if the acidity level are below 5.8 in growth or 6.5 in flowering, then it can easily be increased by introducing a little of this product into the water.

How to use Hesi PH +

Add the Hesi + directly to the irrigation water following the manufacturer's instructions and with a dipper if necessary.

Measure the irrigation water PH in the growth stage, if it is below 5.8, add a little of Hesi PH +.

Measure the irrigation water PH in the flowering phase, if it is below 6.5, add a little of Hesi PH +.

Measure again to make sure that the irrigation water has the right PH.

Hesi PH + can be used in conjunction with other fertilizers and nutrients.
