THC PH down
The easiest way to understand pH is to think of it as being a number between 0 and 14. The number 7 is midway and represents neutrality. Numbers above 7 are alkaline and numbers below 7 are acidic.
Most plants grow in slightly acidic condition and this provides optimum take up of nutrient elements.
THC pH UP & DOWN can be used to move pH level in your solution using the two adjuster solutions.
Here at THC we recommend testing your solution on average twice a week depending on your feeding parameters. Use THC pH Test Kits to test your solution.
