In chemistry, pH is a scale used to specify how acidic or basic a water-based solution is. Acidic solutions have a lower pH, while basic solutions have a higher pH. At room temperature, pure water is neither acidic nor basic and has a pH of 7
Your soil or waters pH level will effect the availability of certain nutrients, Extreme pH values decrease the availability of most nutrients. Low pH reduces the availability of the macro- and secondary nutrients, while high pH reduces the availability of most micronutrients. Microbial activity may also be reduced or changed.
The optimal pH when growing cannabis is between 5.5 and 6.5, In this range the nutrients your plant needs to thrive are available to their fullest potential.
You can control the pH in your water using a liquid or a water soluble powder pH+(pH up) or pH- (pH down)
You can check the pH levels of your water and soil using a pH Meter, You can find all of these items at your local hydroponics store, garden center or right here on our site!
