General Hydroponics pH Test Indicator, 8 fl oz

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.

These drops are still the most reliable pH test in my experience. The electronic devices may be more precise to the decimal point, but they always eventually drift or need calibrating, or replacing. For my purposes, indicator drops is the easiest test to do every day, and I know I can rely on its color indication for a pH measure of water with nutrients for plants, and only use my electronic pH tester pen as a backup. I use this large bottle to refill a dropper bottle that came with a GH testing kit.

we love this and use it often

if you been having to buy pH pen after pen like me get this can't go wrong colors don't lie and it shows red below 5.8 yellow sweet spot with green going a little higher around 7.0 so get solution

always gives me a good reading. My plants are thriving because of this great item.

Easy to use and will use it again in the future,

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.

long story short... i've been using this for years because i hate having to deal with pens and batteries and calibrating ,this is just easier for me and it works great

best place i could find
