Reliable pH Test Strips
Alfred’s pH Test Strips are quick, easy, and reliable! Firstly, don’t take any chances, no other nutrient solution characteristic is more important for healthy plants. Secondly, without the correct acidity/alkalinity, plants wont uptake nutrients.
Then, dip the strip testing zone of the litmus paper in a sample of water or nutrient solution, hold for 3-5 seconds, and you’re done. So, remove the strip from the solution, and match its’ color to the pH Range Color Chart. Because, the closest matching color is your approximate pH level. Finally, compare this pH level to your plants required range of pH, and adjust your nutrient solution as needed.
