HY-PRO PH- (Grow)
THE POWER OF PH IN PLANT AND SUBSTRATE NUTRITION
Your goal as a greenhouse grower is to maintain a stable pH over the life of the crop. This is not an easy task since many factors can affect pH in your substrate. The pH can go up or down in a matter of weeks and if you wait for deficiency or toxicity symptoms to develop, you have already compromised the health of the crop and your profits. Each plant species has a preferred pH; in general, the optimal range for maximum growth is 5.5 to 6.0. Plants experience pH through their roots. Root hairs are very sensitive to any changes that occur in the environment, especially variations in moisture or concentrations of nutrients in your substrate mix. Hy-Pro PH- (grow) is made with a nitric acid base and helps young and growing plants by also providing extra nitrogen.
