Subject: pH Down Просто какое-то средство для понижения показателя рн?A good pH control solution is one that you use only once: when you start your system. Well,we don’t claim that we got quite that; not in every situation and with every nutrient. But in the controls that we have done in our greenhouse, using the pH Down in combination with our Flora-series nutrient and Mineral Magic, we have grown plants for weeks without having to readjust the pH. In some of the smaller systems the pH would drift slowly down, and adding a little of our pH Up would bring it back to the desired range. In others, the pH would stay very close to a beautiful 6.0. |
