  • can I test the ppm with this soulution
    Hello Michael, Thank you for your inquiry. The General Hydroponics 1500 PPM Reference Solution is not used to test solution but instead to calibrate PPM or EC meters to ensure they give accurate information. The solution by itself will not help you ascertain your PPM. Try checking our Testing Equipment tab for PPM meter options they start at only $19.99. Best Regards, Atlantis Hydroponics
