pH + for growing Marijuana

pH + is a liquid pH that controls and stabilizes the pH of the Marijuana plants incorporating silicate, an element frequently to raise the pH of the solution being especially useful for growers that use demineralized water or has passed through an osmosis filter.

The lack of silicate can be a disavantage in hydroponic systems. Due to its limited solubility, it is difficult to add enough in the nutrient solution. A correct pH level is crucial to ensure a proper absorption of minerals by the plants, however, there is not an ideal pH so it must be adjusted according to each plant. A high pH level generally promotes the absorption of cations. In this way, General Hydroponics recommends a moderate pH level, of between 5.5 and 6.2

pH + should be apply only once at the starting of the cultivation system, the pH will remain stable throughout the life cycle of the plant. In some farming systems however, a gradual drop in the pH can be observed so we recommend to use a little of pH + to recover the correct pH.

Available in 1L bottles.
