Best pH tester for your plants! Lasts forever!

Water isn't just water for monsteras, philodendrons, and other $$$ aroids. I started using distilled water, and it was recommended that I should be testing the pH of water nutrient solution for my specific plants. Why? Nutrient lockout is a real thing. If the pH of your aroid feed water isn't btw 5.5-6.5 ph, your plant may not absorb what it needs. So this big bottle of GH Tester is perfect! It's so economical that I test every single batch of feed water daily so each type of plant can get the perfect amount of nutrients. My little succulents get feed water with 6-7 ph. Three drops in a tablespoon of feed water is all you need to test. Get the GH PH Up and GH PH Down bottles to make any adjustments. Waaaay cheaper than the tiny bottles on amazon. 10/10. Will eventually buy again.

Awesome!

Better of getting the big one than the little one there is much more for a little more money plus it came fast. The only down side i can think of is you can't buy it with the glass and dropper but other than that worth it.
