This PH manual test kit is great for any grower who is on a budget and cannot afford a PH meter, but still wishes to test the PH level of their nutrient solution.
This Ph test kit ranges from 6.0 - 7.6 on the colour coded card.
How To Use
With a syringe or pipette pour 1ml of your nutrient solution into the test tube.
Add 1 drop of the re-agent into the solution and shake the tube well.
Now you can match the colour of the solution to the test card colours to determine the PH level.
