Terra Aquatica pH+ Up 500 ml - (multilingual label incl. DE, ENG)

For all cultivation methods: hydroponics and soil

This new concept of pH management will allow you to adjust the pH, especially for fast-growing plants.

As growers, we always have a wishlist, and at the very top of the list is a pH buffer that would work so well that we could go on a two-week vacation and come back to find the pH value in the nutrient solution still the same. The problem is that this can only be achieved when the nutrition is weak, there is not much activity in the solution, and your plants are growing at an average pace.

If the growth is rapid and a large amount of ions are being removed, and there are complex interactions in the solution, such stability is unthinkable. However, today we are not helpless. Today, we can achieve satisfactory stability and additional benefits.

A solution with good pH management is one where you set the pH only once, at the start of the system. We are not claiming that we have achieved exactly that, and not in every situation and with every nutrient. But when it comes to pH management, which we have tried in our greenhouses using pH Down products in combination with Flora Series and Mineral Magic nutrition, plant cultivation has been going on for several weeks without the need to adjust the pH. In some smaller systems, the pH easily decreases, but after adding a small amount of pH Up, it rises to the desired level again. In other cases, the pH remains very close to the almost ideal value of 6.0.

The ideal pH value is actually the most important. A high pH promotes the intake of cations, and conversely, a low pH promotes the intake of anions. So when choosing pH, compromises have to be made. Usually, a safe range with values of 5.5 to 6.5 is recommended. We advise sticking to the lower value, so from 5.5 to 6.2.

As for raising the pH value in the solution, this will be useful especially for growers using osmosis or demineralized water. This new version contains silicate, which improves the plant environment. The lack of silicate can be a limiting factor in hydroponics. This is because it is poorly soluble, making it difficult to add enough to the solution. Therefore, we always add it to our products whenever possible.
