Watering: Difference between revisions

== pH ==

The pH of the water should be between 6.2 and 6.7. Note to also measure pH after adding nutrients to the water. If it's too high for too low, the nutrient intake will be blocked. This is an especially important rule to observe when using nutrient formulas as to not waste them! It's important to note that pH is a logarithmic scale, meaning that 6 pH is 10 times more acidic than 7 pH.

 

It's a good idea to check your tap water with a digital pH meter as it will vary depending on your geographical location. If water is too alkaline (pH too high) a few drops of lemon juice or vinegar can be added. To increase pH you can add dolomite lime. In general, cannabis prefers an acidic environment (<7 pH).
