Water is vital to plants, keeping plants cool in hot weather and carrying nutrients to make them grow. 

It is essential to use water that is most suitable for your plants. Water out of the tap usually contains many minerals and harsh additives like chlorine and ammonia (chloramine). Additionally, tap water can vary in pH from high to low depending on location and water system. 

There are tools available that can measure the pH (potential Hydrogen) and the parts per million (ppm) of your water. High pH means the water is too alkaline, and low pH means the water is too acidic. Neither extreme is desirable. 

There are special filters available to remove most impurities from your water supply. 

Reverse osmosis water filters can help to treat your water and remove unwanted materials, which can affect pH and ppm readings. 

Pretreating your water to make it as perfect as possible for your grow is a sound cultivation best practice.  

Cannabis grown with tainted water won’t thrive as well as it will with water at the proper pH, and free from additives and heavy metals. 

The best nutrient options will have the added value of being a “titration” style nutrient line and will have minimal “mixing” to obtain complete nutrition.
