General Hydroponics PH Test Indicator, 8-Ounce

Accurate, affordable, lasts a long time, and so easy to use. I’m tired of expensive ph meters breaking on me. I put this in an oral syringe so I don’t have to keep opening the bottle every use. You only need a few drops.

Tried and true. Ol faithful. Never needs to be calibrated. Highly recommended

Product is great and works as it should. My only problem is user error, no fault of the company's. I neglected to order the kit with the test vial. Fortunately, I have test vials for my aquariums, although their dimensions are slightly different from those in the photos of the test kits. If anyone happens to know, off-hand, what size the test vials are, I would greatly appreciate the info, for accuracy's sake. I'd just go ahead and order the kit, but this took a few weeks in shipping(no fault to the postal service; it's just the times we're living in right now. Thanks for a great product that is far more reliable than my constantly-needs-calibrated digital ph meter! Namaste

I was using it to test the ph of distilled water. Matched the expensive testing strips for ph

Works like it should

I ordered this PH test kit because it was rated highly and was inexpensive for the amount in the bottle. I expected a decent test color chart, not the wide ranging few colored stripes on the bottle. The stripes jump from 5.0 to 6.0 then 6.5 to 7.0 then to 8.0 and finally 8.5 I'm looking at a PH level chart for hydroponic growing and several vegetables are in the 5.0 - 5.5 range and nothing is over 7.0, so how about giving us a 5.5 stripe and a 7.5 one and doing away with the 8.0 and 8.5 stripes? Or, assuming there are things that require that range how about making them a little more narrow and fitting all the .5's in ?? Seems pretty cheap and dumb to me to leave them out. I am disappointed and won't buy again as I don't need to be scratching my head and squinting at the strips trying to make a decision, is it x or y?

Better than ph meter

accurate every time, unlike ph pens that need expensive chemicals to keep accurate and constant calibration. WAY less expensive than ph pens.

Can’t find this in Canada anymore and this was the best price. Would buy again. Works like it supposed to.

Love this stuff I don’t even use battery operated probes anymore haven’t had a problem with a nutrient lock since I switched to this product I pull 2 pounds of Bud every time consistently I suggest buying this product now as Canada has recently band it from use.
