thatman Posted March 4 Author Share Posted March 4 I would normally know exactly how much pH down to use, but the 1litre bottle i usually buy has changed from 81% concentrate down to 30%,(for the same price). I have never used litmus paper, does the paper change to the similar colours of a liquid test kit? 1 Link to comment Share on other sites More sharing options...

yan Posted March 4 Share Posted March 4 I use the liquid kits where you mix 1ml of your nutrient solution with a drop of the test solution whatever it is and compare the result to a colour chart. Nobody seems to mention these so I wonder if they’re crap and I’m wasting my time. The colour changes from green to yellow when I add ph down and test again though so they do seem like they work to some extent. 2 Link to comment Share on other sites More sharing options...

No they're not crap, they're cheap and reliable, but not as accurate or convenient as a pH meter when it's calibrated and working! Tbh measuring to the nearest 0.5 pH is good enough for plants. All pH meters have a life, the better ones offer replaceable electrodes. Hanna aren't too bad for the money. How many people calibrate theirs regularly or keep the electrode wet with storage solution between uses?

They work, as long as you're not color blind.....like me! 2 Link to comment Share on other sites More sharing options...
